By request of the online LUMI group, I close the previous (13-th) part of our logbook and open a new -- perhaps the last on IBM -- section 14. You can inspect earlier parts by the commands LL5-LL13 (parts 1-4 no longer exist on IBM, they were deleted by the system), where LL13 = LIST 'F11LEV.H1.LUMI.LOGBOOK.PART13' 08.07.1996 ===== OnLine ==== H1KFOM === Important VME-addresses .... If You put into B0B00B00 value 2 -> Usik's applications will update Sigma visible for ET&PD and PhArm Rate methods from DPM (at case if it was made changings at this values). If You put into B0B00B00 the value 3 - only ET&PD sigma visible will be updated for Usik's applications. If You put into B0B00B00 the value 4 - only PhArm sigma visible will be updated for Usik's applications. Both 'Sigmas' are read from DPM during initialization of Usik's applications only (one time only). VME address B0B00B0C is used for switching on PhotonArm Method Lumi calculation showing at HERA,H1 Control Room and xshlu,shlu etc. If You put into this cell the value 3 - PhotonArm Lumi will be shown, at another case - ET&PD-method. Now the value '3' is installed with 'Start Lumi Measurement' button at T_MonitorNC and 'not 3' with 'Stop Lumi Measurement' button (for removing of non-right Lumi values at Usik's pictures from so-called 'readout' noice at pause between neighbours Lumi RUNs). 08/07/96 =================== nguyenl === Lumi RUN# 995 Start - End of Run 995: 8/7/96 8:06:39 - 14:16:21 Collision time for H1Run - physics: 9:03:26 - 14:16:21 Currents at the begining (mA): Ie= 19.7, Ip= 33.83 max lumi value, (last record): 2.057, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.691, (0.691) mkb-1 s-1 mA-2 collided bunches = 175 e+(-) bunches = 189, p-bunches = 181 e-pilot b. = 14, p-pilot b. = 6 HERA total lumi: 25.91 nb-1 HERA - physics: 21.75 nb-1 H1Run - physics: 14.28 nb-1 H1data - physics: 10.5 nb-1 H1 operation eff.: 65 % , DT corr.: 73 % , Tot eff.: 48 % H1 Runs: 147781 - 147815 P.S.

V.Andreev found that at Data'96 non-linearity effects at VCdep energy are significantly less then at Data'95. First estimations show that at Data'95 significant unlinearity was appeared at low energy near VCdep<2.0GeV and at Data'96 - only with VCdep<0.5GeV. Details are at V.Andreev's hands. Possible explanations are connected with famous VCdep FADC window shift on 40 nsec (see earlier messages at LL13). 08.07.1996 ================= H01GOG === Lumi Working Group Meeting The meeting will take place 10.07.96 at 19:00 in one of the seminar rooms (3, 4, 5 ?). Everybody is invited to contribute on his/her activities in H1. 08.07.1996 ===== Calibr ==== H1KFOM === Selection for Calibration ... It was discussed and decided to use the new strategy of events selec- tion for calibration and some monitoring procedures. From all LUMIMON-data sets'96 it will selected all needed events into single index file with next FPACK-options: SELECT in RECNAME = RUNEVENT NUMRA=147095: & CLASS = 16:20 SELECT in RECNAME = RUNEVENT NUMRA=147095: & CLASS = 3 CLASS = 6 SELECT in RECNAME = RUNEVENT NUMRA=147095: & CLASS = 4 CLASS = 5 You can see that all needed for calibration events will be selected with mentioned FPACK-options (ETPDnVC,ETPDVC,S9291 and ET44VC). S93- events will be kept at this file too (request of V.Andreev for PD,PDlow,PDhigh thresholds monitoring etc.) It was decided to proclaim as first H1Run for 1A-calibration samples of 1996 year the 147095 first H1Run after last H1Lumi Dedicated Runs. Data from this Run were recorded at 164th LUMIMON. So 164th LUMIMON is first LUMIMON'96 which is included into 'mass selection'. First 24 LUMIMON-data sets'96 were processed and it was created first index file with 77269 events of mentioned classes. fomenko h1 1263600 Jul 8 21:05 H1KFOM.CALIBR.M164187.IND.C00 You can see that only 1.3Mbyte of Disk Space is used for 77K events. If You remember at previous year this quantity of events got near 150 Mbytes. So we hope on very economy using of storages at this year for selected events. When next portion of LUMIMONs will be ready it will be created new index file: H1KFOM.CALIBR.M188212.IND.C00 for example and it will be possible to combine all events into one index file: H1KFOM.CALIBR.M164212.IND.C00 etc. So at any time at /acs/data/lumi/96-directory it must exist one additional data set H1KFOM.CALIBR.M164XXX.IND.C00-type where XXX -last LUMIMON'96-number which is included into this index file. Any calibration job or any monitoring job can work with this INDEX-file and it would be possible to select calibrations sample with NUMRA=XXXXXX:YYYYYY options and with CLASS = 4 CLASS = 5 NOTCLASS = 6 (ETPDnVC-sample), CLASS = 4 CLASS = 5 CLASS = 6 (ETPDVC-sample), CLASS = 16:17 (S9291-sample), CLASS = 3 CLASS = 6 (ET44VC-sample) and CLASS = 18 (S93-sample). At H1Runs 147095-147812 (LUMIMONs 164-187) it were selected without accounting of H1Runs quality: It is needed: | 16983 etpdnvc OK V 34363 etpdvc not OK too high quantity - S95 prescale factor 0.4 9013 et44vc it would be good a little more- S90 prescale factor 1.2 3638 S92 not OK extremly low quantity - S92 prescale factor 2.0 13061 S91 OK 10471 S93 OK Situation is the same as at previous year. It is needed to make some steps on incrementing of S92-sample - it is important for quality of calibration. The more S92-events the better calibration precision. 08.07.1996 ================= H01GOG === Useful files on dice2 The are several files with useful information in my home directory on dice2: ~nellyg/gmp96.text ~nellyg/hlumi.y96.text Similar files with 1994, 1995 data exist as well. 09.07.1996 = 10:00 ========= H01LNS === List of Lumi Runs by PL.gt.0= Tue Jul 9 09:00 1996s LUMI RUNS TAKEN FROM LLO AND SELECTED BY NONZERO PHYSICS LUMI ------------------------------------------------------------------- 28/06/96 Lumi RUN# 979 H1 Runs: 144727 - 144734 physics: 1.34 nb-1 01/07/96 Lumi RUN# 982 H1 Runs: 145505 - 145573 physics: 0.04 nb-1 04/07/96 Lumi RUN# 987 H1 Runs: 146352 - 146544 physics: 2.87 nb-1 06/07/96 Lumi RUN# 990 H1 Runs: 146968 - 147178 physics: 8.35 nb-1 06/07/96 Lumi RUN# 991 H1 Runs: 147236 - 147264 physics: 4.95 nb-1 07/07/96 Lumi RUN# 993 H1 Runs: 147396 - 147558 physics: 3.46 nb-1 08/07/96 Lumi RUN# 994 H1 Runs: 147574 - 147744 physics: 20.63 nb-1 08/07/96 Lumi RUN# 995 H1 Runs: 147781 - 147815 physics: 10.50 nb-1 09/07/96 =================== Haller === Lumi RUN# 996 Start - End of Run 996: 8/7/96 22:59:10 - 10:15:13 Collision time for H1Run - physics: 1:06:47 - 10:15:13 Currents at the begining (mA): Ie= 27.43, Ip= 53.65 max lumi value, (last record): 3.564, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.617, (0.691) mkb-1 s-1 mA-2 collided bunches = 175 e+(-) bunches = 189, p-bunches = 181 e-pilot b. = 14, p-pilot b. = 6 HERA total lumi: 76.65 nb-1 HERA - physics: 54.99 nb-1 H1Run - physics: 40.03 nb-1 H1data - physics: 29.07 nb-1 H1 operation eff.: 72 % , DT corr.: 72 % , Tot eff.: 52 % H1 Runs: 147893 - 147996 09/07/96 =================== nguyen === Lumi RUN# 997 Start - End of Run 997: 9/7/96 15:45:45 - 16:35:58 Collision time for H1Run - physics: 16:35:51 - 16:35:58 Currents at the begining (mA): Ie= 23.77, Ip= 41.24 max lumi value, (last record): 0.943, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.19, (0.691) mkb-1 s-1 mA-2 collided bunches = 0 e+(-) bunches = 177, p-bunches = 0 e-pilot b. = 177, p-pilot b. = 0 HERA total lumi: 0.42 nb-1 HERA - physics: 0 nb-1 H1Run - physics: 0 nb-1 H1data - physics: 0 nb-1 H1 operation eff.: 0 % , DT corr.: 0 % , Tot eff.: 0 % H1 Runs: 148056 - 148082 10/07/96 =================== borras === Lumi RUN# 998 Start - End of Run 998: 10/7/96 3:29:03 - 4:22:32 Collision time for H1Run - physics: 4:22:24 - 4:22:32 Currents at the begining (mA): Ie= 24.1, Ip= 56.84 max lumi value, (last record): 3.099, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.53, (0.691) mkb-1 s-1 mA-2 collided bunches = 174 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 6 HERA total lumi: 5.66 nb-1 HERA - physics: 2.93 nb-1 H1Run - physics: 0 nb-1 H1data - physics: 0 nb-1 H1 operation eff.: 0 % , DT corr.: 0 % , Tot eff.: 0 % H1 Runs: 148145 - 148153 10.07.1996 ================= H1KFOM === H1Lumi Subtriggers Prescales Date: Tue, 9 Jul 1996 13:17:15 +0200 (MST) From: Alexandre Fomenko To: hoffmann@dice2.desy.de Subject: Prescales for S95,S92 and S90 Hello, dear Dirk, ...... Can You help to H1Lumi team at 'fine' tuning of prescales for mentioned subtriggers? I hope that at mentioned tuning H1Lumi Monitoring triggers will be at previous year quota but it is very needed to make changing of prescales inside this quota. S90 prescale decrementing on factor 1.2 S92 prescale decrementing on factor 2.0 S95 prescale incrementing on factor 0.4 At my opinion this question is very important for supporting of good level systematic error from calibration at Luminosity calculation (at previous year it was fixed level of this systematic error near 0.5-0.8%). ..... Date: Tue, 9 Jul 1996 17:47:24 +0200 (MST) From: Eckhard Elsen To: Dirk Hoffmann Cc: Alexandre Fomenko , Felix Sefkow Subject: Re: Prescales for S95,S92 and S90 Dear Sasha, the new prescales have just been loaded. Cheers, Eckhard 10.07.1996 ================= H1KFOM === View on LUMIMON-data Yesterday after end of Lumi RUN# 996 the LUMIMON 197th was last data set. From 164th up to 197th LUMIMONs it were selected 105963 events needed for calibration and monitoring. These events are at next proportions (Runs 147095-147996 - only G+M Runs): ETPDnVC - 23438 S94 - 12689 <- OK ETPDVC - 47531 S95 - 5475 <- high quantity S92 - 4869 <- extremly low quantity ET44VC - 12317 S90 - 5347 <- it would be good if a little more S93 - 13742 <- OK S91 - 18317 <- OK It was made attempt to make processing of this data with latest h1rec with latest calibration (from H1Lumi Dedicated Runs 147087-147094). Next results were produced: 1) ETPDnVC-events (only G+M Runs): Runs 147119-147996 (ET&PD&nVC-sample - near 23K events) all events xetcut xetcut&vcdepcut 23438 ev. 17650 ev. 12081 ev. Mean Sigma Mean Sigma Mean Sigma 27.53 1.33 27.58 1.29 27.62 1.23 <- FIT (gauss+ax+b) +-0.01 +-0.01 +-0.01 <- errors from fit 2) ETPDVC-events (only G+M Runs): Runs 147119-147996 (ET&PD&nVC-sample - near 48K events) all events xetcut 47531 ev. 36509 ev. Mean Sigma Mean Sigma 27.24 1.55 27.25 1.52 <- FIT (gauss+ax+b) +-0.01 +-0.01 <- errors from fit 3) Photon Arm Global Energy Shift: Runs 147119-147996 (S92-sample - 4869 events) selection into 70th histo bins 70 0 35 pdrec<9998 (good reconstr.) and |vcdep|<0.3GeV -> 3926 entries into 70th histo: Photon Arm Global Energy Shift has value from: -5%+-0.1% up to -3.5%+-0.6% for different fit boundaries (6-20)-35 GeV; Resoluition of detector estimated from 19%+-1.0% up to 6%+-4%. So significant differencies can be explained with low statistics of PDnVC-sample for estimation of mentioned values. 4) Thresholds (S93-events for PDlow,PDhigh,PD and S91 - for ET) PDlow_Thr: 4.98+-0.03 GeV Sharpness: 0.60+-0.02 GeV; PD_Thr: 5.74+-0.03 GeV Sharpness: 0.64+-0.02 GeV; PDhigh_Thr: 14.80+-0.07 GeV Sharpness: 0.99+-0.05 GeV; ET_Thr 7.2 +-0.1 GeV Sharpness: 0.82+-0.05 GeV; As seems value for PD-thresholds are shifted on 4-5% into low direction (Global Shifts predicted this behaivour) and ET threshold is shifted into high direction (as seems). From previous experience it was found that thresholds which are defined from Random Trigger (PD-family) are the same defined with S93-triggered events. Only 444 events with Random Trigger were fixed at first useful 34 LUMIMON data sets'96. 5) There is some evidence that resolution values for ETrec+PDrec energy distribution had been changed from 990th Lumi RUN up to 996th Lumi RUN from 1.00 GeV up to 1.80 GeV for best selection at ETPDnVC-samples. Conclusion: it is needed first 1A-sample calibration as soon as enough statistics will be collected. For any case I keep LOOK-binary data set with mentioned data at DESY IBM and anybody can play with 100th tuple from this LOOK-binary. H1KFOM.LOOK.R147117 FAST02 3010200E 00000 DASD 10.07.1996 ===== OnLine ==== H1KFOM === OnLine Programs Development Today it was made new release of H1LumiOnLineFIC2-program with updating of 1 subroutine (Calibration.f). Changings were connected with removing of bug which was involved into operation of this subroutine at 25.06.96 (see message at LL13). As result VCs-response was not OnLine calibrated during all period from 25.06.1996 up to now. As seems there were no any influences on Off-line processing (due to up to now Relation Coefficient for CCvcs is not involved). But there were enough significant influence on 4 new values which are written into LUMMbank: 735 PDDEP1 I 0 30000 ! Mean Value of Photon Arm Deposited 736 PDDEP2 I 0 30000 ! Mean Value of Photon Arm Deposited 737 PDREC1 I 0 30000 ! Mean Value of Photon Arm Reconstructed 738 PDREC1 I 0 30000 !

Here the L4Histos for the Energy Sums of Etag and Et44 are considered. For every LumiRun, for every H1Run, by steps of H1Runs the values of Entries, MEAN, RMS were calculated and checked. Only the histos having N_of_Entries .GE. 100 were analyzed. The MEAN and RMS were calculated via the Peak_Finder, that makes the values much less dependable on the background. The alarming values the MEAN Energy for H1Run were spotted (see later). For every LumiRun all H1Run_histos were summed, and Entries, MEAN, RMS were calculated for total LR#'s and displayed in the following TABLE TABLE 1: LR#'s 987 - 996 at the level of the total LumiRuns ----------------------------------------------------------------------- LR# 987 NH1R= 14 Etag: 8048 18.20+/-1.22 Et44: 4015 25.84+/-3.01 LR# 990 NH1R= 2 Etag: 452 31.10+/-1.15 Et44: 572 26.50+/-3.70 ----------------------------------------------------------------------- LR# 991 NH1R= 2 Etag: 1035 26.90+/-1.60 Et44: 500 25.90+/-2.25 LR# 993 NH1R= 35 Etag: 10892 26.45+/-1.46 Et44: 3510 25.93+/-2.95 ----------------------------------------------------------------------- LR# 994 NH1R= 28 Etag: 13990 27.36+/-1.16 Et44: 3806 25.63+/-3.32 LR# 995 NH1R= 14 Etag: 11360 27.44+/-1.41 Et44: 3053 26.09+/-2.97 LR# 996 NH1R= 28 Etag: 19697 27.41+/-2.06 Et44: 5529 25.90+/-3.08 ----------------------------------------------------------------------- TABLE 2: LR#'s 987, 990, more detailed at the level of each H1Run ----------------------------------------------------------------------- Note: The summing lines (ALLH1R) show the same values as in the Table1 ---------------------------------------------------------------------- 987 146399 sEtag: 1069 96% 4.7 +/- 0.5 sEt44: 114 57% 24.1 +/- 3.3 987 146401 sEtag: 131 89% 4.7 +/- 0.5 sEt44: 8 23% 17.7 +/- 0.3 987 146406 sEtag: 290 99% 4.7 +/- 0.6 sEt44: 26 58% 29.7 +/- 2.2 987 146407 sEtag: 906 90% 4.7 +/- 0.5 sEt44: 100 73% 24.6 +/- 4.1 987 146408 sEtag: 461 94% 4.7 +/- 0.5 sEt44: 62 70% 27.9 +/- 3.3 987 146443 sEtag: 660 43% 17.2 +/- 3.6 sEt44: 110 68% 25.8 +/- 3.1 987 146444 sEtag: 649 40% 26.5 +/- 1.4 sEt44: 85 74% 25.8 +/- 3.9 987 146448 sEtag: 184 62% 26.8 +/- 1.6 sEt44: 45 92% 26.6 +/- 3.8 987 146453 sEtag: 239 63% 26.3 +/- 1.3 sEt44: 23 86% 27.0 +/- 2.5 987 146466 sEtag: 543 79% 26.9 +/- 1.3 sEt44: 45 80% 26.2 +/- 3.9 987 146474 sEtag: 169 94% 27.0 +/- 1.5 sEt44: 15 46% 28.5 +/- 0.5 987 146477 sEtag: 830 80% 27.0 +/- 1.5 sEt44: 117 75% 27.3 +/- 4.0 987 146493 sEtag: 1268 50% 26.6 +/- 1.1 sEt44: 2061 90% 25.4 +/- 3.6 987 146518 sEtag: 649 56% 27.1 +/- 1.2 sEt44: 1204 92% 25.2 +/- 3.7 ---------------------------------------------------------------------- 987 ALLH1R sEtag: 8048 73% 18.2 +/- 1.2 sEt44: 4015 70% 25.8 +/- 3.0 ---------------------------------------------------------------------- 990 147132 sEtag: 297 70% 27.1 +/- 1.4 sEt44: 75 96% 26.9 +/- 3.9 990 147151 sEtag: 155 0% 35.1 +/- 0.9 sEt44: 497 91% 26.1 +/- 3.5 ---------------------------------------------------------------------- 990 ALLH1R sEtag: 452 35% 31.1 +/- 1.1 sEt44: 572 93% 26.5 +/- 3.7 ---------------------------------------------------------------------- *) For other LR#'s the Tables like this one don't carry any surprizes ---------------------------------------------------------------------- CONCLUSIONS: 1. There was an ALARM for LR# 987, giving E_sum(Etag) = 18.2 GeV 2. There was an ALARM for LR# 990, giving E_sum(Etag) = 31.1 GeV 3. These 2 LumiRuns were taken at the beginning of the HERA datataking. See a detailed picture in Table 2, at the real time, by each H1Run. 4. The Energy values for all the other LumiRuns were reasonably OK. 5. A detailed pictures by each H1Run have not revealed any alarming. 6. Between LR# 993 and 994 the E_sum(Etag) changed ~1GeV UP, WARNING? This WARNING was canceled, because A.Fomenko informed, that the new CALIBRATION was put to DB around this time. 7. I don't know, whether the LumiRuns 987, 990 (see 1,2) have been included to THIS CALIBRATION by A.Fomenko. Tables 1, 2 show, with a delay, that it would be unreasonable. 8. For E_sum(Et44) neither alarms, no changings were noticed, it is OK 9. But as ussially, the E_sum for Et44 is ~2GeV lower than for Etag, OK 10.07.1996 ===== OnLine ==== H1KFOM === Fast Tilt Monitoring Tool.. Yesterday Igor Sheviakov finished the creation and testing of fast tilt monitoring tool. Today during current Lumi RUN# 999 it was possible to see advantages of this tool in compare with old one. Old tool was pure SW tool and worked with near 5-7 Hz. New tool is using new additional FIC-processor (LUMI2) and the some HW tools for photon beam position estimation. New tool is working with 500Hz rate (two order faster as old one(!)). Lumi2 FIC2 program was written exlusively by I.Sheviakov. Program is included into WatchDog service too. Program is using Direct Memory Access option for access to VME-addresses and only at this case it was possible to make monitoring of often 'bus-error's without program crash (with ordinary VME-access 'bus-error's immediately are crashing the program).Lumi2 FIC2 processor has lowest priority among all processors which are working at H1Lumi Master Crate (FIC1-Master,FIC1-Slave,VIC,FIC2-Lumi,MacVEE1,MacVee2,Sparc,FIC2-Lumi2) There is else one important VME-addresse for this case : If You put into B0B00B10 value 3 ->Usik's applications will update Xpd,Ypd with old manner. If You put into B0B00B10 value 4 - it is possible to use new - fast tilt monitoring tool. As seems this is fantastically fast response on last requirements of HERA-people. And Egor's Next Great Victory. 10.07.1996 ===== OnLine ==== H1KFOM === SPACAL Cluster Trigger Rate Yesterday Ueli Straumann wrote into h1run pinboard (20:00): "... We plan to feed the SPACAL cluster trigger rate to the HERA controlroom to try to optimise the electron beam steering with that...." Today 'that' was made through H1Lumi-applications(as temporary decision may be) by Egor's hand. From 13:25 the H1Lumi 'Monitoring Counter' (nonmovable little Cherenkov Water Counter) Rate at LTV-application was changed on SPACAL cluster trigger rate. Usik's xshlu,shlu tools shows from this time 'that' rate too. 10.07.1996 ===== OnLine ==== H1KFOM === H1Lumi OnLineSW Tools Status Today it was made 1st attempt to collect into one list all OnLine SW products which are ready on today for working inside H1Lumi OnLine System.

Today during Lumi RUN# 999 me and Egor looked different signs which are pointing in very low ET acceptance during part of this Lumi RUN: 1) Lumi calculated with ET&PD method has only 66% from Lumi calculated with PhArm method; 2) Very specific OnLineXet/Yet plot (extremly low population of hits at 'right' side of ET (Xet>0.0cm); 3) Very specific OnLine ETrec and PD energy distribution for ET&PD&nVC- events - most probable ETrec energy became near 15 GeV and most probable PhArmEnergy_rec became near 12.5 GeV. It was seen from Egor's OnLineLongHistory pictures that acceptnace was changed during all Lumi RUN into decrementing direction. As seems HERA-people at this year will be not 'find' optimal ET-accep- tance for H1 Interaction Point (due to Photon Arm method Lumi was more or less stable during mentioned decremention of ET-acceptance) and there are some prognoses that there will be a lot of difficult work for S.Levonian and V.Andreev to define 'right' ET and ET44-acceptances for Data Taking'96 due to as it was seen today ET-acceptnace is changing even inside single Lumi RUN. May be due to this reason resolution at ETrec+PDrec spectra became not so good as earlier(more population of hits at ET near boundaries or changing of most probable energies at ETrec and PDrec spectra). 10/07/96 =================== lehner === Lumi RUN# 999 (presuperjubile Start - End of Run 999: 10/7/96 8:59:42 - 19:31:38 Collision time for H1Run - physics: 13:20:04 - 19:31:38 Currents at the begining (mA): Ie= 23.3, Ip= 60.18 max lumi value, (last record): 3.625, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.522, (0.691) mkb-1 s-1 mA-2 collided bunches = 173 e+(-) bunches = 188, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 7 HERA total lumi: 47.59 nb-1 HERA - physics: 32.76 nb-1 H1Run - physics: 9.11 nb-1 H1data - physics: 2.86 nb-1 H1 operation eff.: 27 % , DT corr.: 31 % , Tot eff.: 8 % H1 Runs: 148177 - 148300 11/07/96 =================== haller === Lumi RUN# 1000(superjubileum) Start - End of Run 1000: 11/7/96 2:48:28 - 7:23:20 Collision time for H1Run - physics: 4:24:31 - 7:23:20 Currents at the begining (mA): Ie= 23.3, Ip= 59.69 max lumi value, (last record): 2.907, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.438, (0.691) mkb-1 s-1 mA-2 collided bunches = 174 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 6 HERA total lumi: 33.37 nb-1 HERA - physics: 32.05 nb-1 H1Run - physics: 14.67 nb-1 H1data - physics: 8.5 nb-1 H1 operation eff.: 45 % , DT corr.: 57 % , Tot eff.: 26 % H1 Runs: 148344 - 148396 11/07/96 =================== haller === Lumi RUN# 1001 Start - End of Run 1001: 11/7/96 7:25:11 - 12:05:41 Collision time for H1Run - physics: 7:25:53 - 12:05:41 Currents at the begining (mA): Ie= 13.31, Ip= 58.33 max lumi value, (last record): 1.531, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.425, (0.691) mkb-1 s-1 mA-2 collided bunches = 174 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 6 HERA total lumi: 21.72 nb-1 HERA - physics: 21.69 nb-1 H1Run - physics: 16.42 nb-1 H1data - physics: 11.33 nb-1 H1 operation eff.: 75 % , DT corr.: 68 % , Tot eff.: 51 % H1 Runs: 148396 - 148433 P.S.

There is no place for 4th digit. Egor removed the showing of Lumi RUN at his window up to Usik's appearing at DESY. P.S. Now all is OK. Update of this window was made succesfully. 11.07.1996 ===== OnLine ==== H1KFOM === OnLine Programs Development Today it was made new release of H1LumiOnLineFIC2-program with updating of 5 subroutines (InitConstant1.f, LumiMonitoring.f, LumiMonitoringPD.f, LRTLBankFill.f, main.f) and with adding of new subroutine - ETPDLumiCorrection.f. Changings were connected with involving of correction for OnLine Luminosity value calculated with ET&PD-method on ET-acceptance changing Correction factor must be inside (0.4-1.7) range not more. Correction factor will be written into 241st word of LRTL-bank. All 220 bunch rates and total rate at LRTL-bank were changed on menti- oned factor (multiplicated) - so it is possible to make step into back direction and to calculate not corrected Lumi value if it will be needed or interesting. Decision about this changings were adopted at yesterday Luminosity working group meeting. These are creation date and memory size of last release: H1LumiOnLineFIC2.......MPST MPS ....247798 Thu, Jul 11, 15:15 1996 Today it was made new release of TwinFIC1-program for Master FIC1 with updating of 1 subroutines (OutBanks.f).

Due to Jan Olsson's intervention it was decided to back to old release of LRTL-bank contents up to approvement of this decision at some meeting. It was happened today at 18:40. It was boot release H1LumiOnLineFIC2 from 10.07.96 10:36 with important correction of bug at Calibration.f-subroutine. VCs again will be calibrated after problems from 26.06.96 up to now. 11.07.1996 ================= H1KFOM === H1Lumi Subtriggers Prescales Yesterday I checked quotas of different useful H1Lumi events recorded on LUMIMON data sets after E.Elsen's prescale tuning: It were checked events from 198-200th LUMIMONs which were recorded mainly during 999th Lumi RUN (Runs 148203-148243): Total - 4617 events ETPDnVC - 925 events S94 - 251 events ETPDVC - 2502 events S94 - 236 events S92 - 257 events S91 - 345 events S93 - 288 events ET44VC - 591 events First impression is good. S92-events quota became more reasonable. ET44VC-events have too reasonable quota. Enough large quota ETPDVC-events connected with overlapping of this type events with S91,S93 and non-H1Lumi subtriggers. It is not bad More events is better then less. 11.07.1996 ===== OnLine ==== H1KFOM === LRTL banks new length test Today during e+injection around 18:00 (when new release of H1Lumi- OnLineFIC2 program was booted into FIC2) it were written some H1Runs. As You know LRTL is writting into H1DataFlow during e+beam presence at HERA. It is good that even little test of 'new length' of LRTL- bank was made: 148593 5674 0 4FFFFFFF 960711 175736 960711 180218 .... 4C52544C:LRTL 27 243 243 243 .... 148609 83 0 4FFFFFFF 960711 183525 960711 183541 .... 4C52544C:LRTL 1 243 243 243 After back to old rtelease first Run with old LRTL-format: 148627 713 0 4FFFFFFF 960711 201200 960711 201224 .... 4C52544C:LRTL 2 242 242 242 ... During Lumi RUN# 1002 again was fixed very low ET-acceptance and again S.Levonian's tools wrote into H1DataBase Integrated Lumi value which less then real value on 25-30%. It is pity. Let's wait of some official decision. 12/07/96 =================== lehner === Lumi RUN# 1002 Start - End of Run 1002: 11/7/96 20:41:20 - 6:58:07 Collision time for H1Run - physics: 21:21:18 - 6:58:07 Currents at the begining (mA): Ie= 26.69, Ip= 50.48 max lumi value, (last record): 2.531, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.437, (0.691) mkb-1 s-1 mA-2 collided bunches = 174 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 6 HERA total lumi: 53.38 nb-1 HERA - physics: 52.66 nb-1 H1Run - physics: 38.93 nb-1 H1data - physics: 28.6 nb-1 H1 operation eff.: 73 % , DT corr.: 73 % , Tot eff.: 54 % H1 Runs: 148631 - 148674 P.S.

This Lumi RUN was recorded with the same p-beam and same e+beam which were used at previous (1003th) Lumi RUN. (e+beam tuning message at HERA TV screen). 13.07.1996 ================= H1KFOM === New LRTL Problems Meeting Yesterday at Phill Biddulph's office it was held meeting for discussing of problems connected with involving of new LRTL-bank contents (correc- ted on ET-acceptance ET&PD-bunch rates and Total ET&PD Rate, involving of 241st word with Correction factor connected with ET-acceptance chan- ging). Phill Biddulph, Jan Olsson, Yuri Soloviev, Nelly Gogitidze and me participated at discussion of questions connected with mentioned problems. Discussion was enough hard, difficult with unwaitable proposals etc. But as seems during this discussion it was became clear that both methods of Lumi measurements at H1 IP show the same Lumi values (less then at ZEUS IP). After moving of H1 Lumi measurements on Photon Arm Rate method became clear that HERA cannot tune maximum (or optimum, or stable during enough large time period) ET-acceptance and it is bad and is serious problem. As seems may be better to back to coincidence method showing to HERA-team (both goals will acieved simultaneously - max Lumi and max and stable ET-acceptance (and ET44-acceptance too as seems). Moving to 'old' and 'new' method is simple - through 'Important VME addresses' see meassage at H1Lumi LogBook from 08.07.96. It was proposed to involve 'analog' ET&PD calculated Lumi into LRTN bank for Photon Arm one (for case LUMM-bank dissapearing from H1 Data Flow). It is needed to note than up to now it was not fixed disappearing of LUMM-banks at H1DataFlow but who knows. Jan Olsson asked to involve the same ET-acceptnace correction factor word into LUMM-bank too due to we have a little asynchronous appearence of LRTL and LUMM bank at H1Data Flow. May be it will be useful. It was pointed in that up to now all integrated lumi values at Black/White TV-screens, HERA-applications and H1Lumi screens and at Run Summaries are from coincidence method Lumi calcilation and involving of correction factor for ET&PD-method will remove current problem of updating of some from Usik's tools. Jan Olsson proposed to make additional (LH2R,LH2T banks) for Photon Arm Lumi Inegrated lumi at H1DataBase (in parallel to existing LH1R,LH1T banks). As seems it is useful only if to keep unchangable LH1R,LH1T banks - i.e. 'remove' OnLine Correction factor with so called off-line 'dividing'. As seems one from main questions is not answered - Luminosity value must be equal value for both method its measureament. Why it is needed to make 'double'-banks at H1DataBase. All H1Community can use ordinary (familiar) LH1R,LH1T-banks. But at case of 'removing' of correction factor it is obviously that using of this banks at 1996 will be non-correct and it would be recommend to use LH2R,LH2T-banks etc. or to use correction factor. As seems this is not best decision. It was decided that we can try new releases after Jan Olsson will prepare update of some tools for writting Integrated Lumi into H1DataBase with 'old manner' after removing of mentioned correction at off-line. The exchange of mails or phone calls will start new period Lumi measurements with new (corrected on ET-acceptance) LRTL-contents. It was discussed the possibility a little earlier tests of our relaeses during first phases of Lumi RUNs due enough large upgrade was made and bugs are possible. Later it was found that after last 2 changing at OnLine of BH 'visible' cross-section values (see LL13 26.06.96 and 07.07.96) nothing was made with S.Levonyan's tool (which recalculated Lumi and Integrated Lumi from LRTL/TCUR-banks contents before writting Integr. Luminosities into H1DataBase - LH1R,LH1T banks) for correction of 'old' cross sections on new one - so all information about Integrated Lumi for first Lumi RUNs of this year are connected with 'non-right' (old) BH 'visible' cross section and (as seems) must be corrected (multiplicated on different correction constant factors for Runs after 144392 and after 147607). As seems there are many questions again connected with mentioned problems and it would be better to involve 'fresh people' into discussion (I.Sheviakov, S.Levonyan) but I am not sure that it will be possible. 13/07/96 =================== haller === Lumi RUN# 1005 Start - End of Run 1005: 13/7/96 20:51:56 - 21:35:57 Collision time for H1Run - physics: 21:35:20 - 21:35:57 Currents at the begining (mA): Ie= 15.4, Ip= 52.91 max lumi value, (last record): 1.753, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.428, (0.691) mkb-1 s-1 mA-2 collided bunches = 0 e+(-) bunches = 0, p-bunches = 180 e-pilot b. = 0, p-pilot b. = 180 HERA total lumi: 2.99 nb-1 HERA - physics: 0 nb-1 H1Run - physics: 0 nb-1 H1data - physics: 0 nb-1 H1 operation eff.: 0 % , DT corr.: 0 % , Tot eff.: 0 % H1 Runs: 149067 - 149080 13/07/96 =================== haller === Lumi RUN# 1006 Start - End of Run 1006: 13/7/96 22:29:00 - 23:16:06 Collision time for H1Run - physics: 23:15:58 - 23:16:06 Currents at the begining (mA): Ie= 27.01, Ip= 52.77 max lumi value, (last record): 0.894, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.235, (0.691) mkb-1 s-1 mA-2 collided bunches = 174 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 6 HERA total lumi: 1.9 nb-1 HERA - physics: 0 nb-1 H1Run - physics: 0 nb-1 H1data - physics: 0 nb-1 H1 operation eff.: 0 % , DT corr.: 0 % , Tot eff.: 0 % H1 Runs: 149082 - 149098 14/07/96 =================== haller === Lumi RUN# 1007 Start - End of Run 1007: 13/7/96 23:27:05 - 1:24:14 Collision time for H1Run - physics: 1:24:05 - 1:24:14 Currents at the begining (mA): Ie= 19.5, Ip= 27.87 max lumi value, (last record): 0.535, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.299, (0.691) mkb-1 s-1 mA-2 collided bunches = 0 e+(-) bunches = 0, p-bunches = 0 e-pilot b. = 0, p-pilot b. = 0 HERA total lumi: 1.74 nb-1 HERA - physics: 0 nb-1 H1Run - physics: 0 nb-1 H1data - physics: 0 nb-1 H1 operation eff.: 0 % , DT corr.: 0 % , Tot eff.: 0 % H1 Runs: 149099 - 149105 14/07/96 =================== borras === Lumi RUN# 1008 Start - End of Run 1008: 14/7/96 14:25:54 - 14:41:32 Collision time for H1Run - physics: 14:41:25 - 14:41:32 Currents at the begining (mA): Ie= 24.74, Ip= 58.00 max lumi value, (last record): 2.108, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.302, (0.691) mkb-1 s-1 mA-2 collided bunches = 0 e+(-) bunches = 187, p-bunches = 0 e-pilot b. = 187, p-pilot b. = 0 HERA total lumi: 0.98 nb-1 HERA - physics: 0 nb-1 H1Run - physics: 0 nb-1 H1data - physics: 0 nb-1 H1 operation eff.: 0 % , DT corr.: 0 % , Tot eff.: 0 % H1 Runs: 149307 - 149308 14.07.1996 ================= H1KFOM === New LRTL Problems Discussion It was proposed to keep 4 days discussion about new contents of LRTL-bank at our LogBook.

Fomenko" Subject: Changes in the LRTL bank Jan Olsson H1 Collaboration DESY F11, Notkestr. 85, 22603 Hamburg 52 Phone (49) (40) 8998 3138 mail address: F11JOL@dsyibm.desy.de CC: Soloviev,Fomenko,Biddulph,Straumann,Sefkow,Levonian,Gogitidze, Fleischer Dear Sasha and Yuri, I just noticed in the LUMI Logbook that an important change has been made in the LRTL bank: The value of the integrated luminosity is now multiplied with a correction factor, calculated online, apparently to adjust the coincidence method value to the single photon method. The correction factor is stored in the LRTL bank, in a new word added at the end. The logbook says that this is based on a decision taken in a mee- ting yesterday. The LRTL bank values are fed into the banks LH1R and LH1T in the Runend job (TCL-job). If they are missing, or when there is a distance between the last LRTL bank and the Run end, a correction is calculated for the Database storage. This is done by software from Sergey Levonian. The question arises: Does the recent change to the Integrated Luminosity value in the LRTL bank respect the software that handles this bank off- line? I would assume that the real offline calculations of the integra- ted luminosity are not affected, only there will be a different set of correction factors to the LH1R / LH1T bank values, maybe smaller than in previous years. But the question is, what happens in the TCL-job, with the corrections that are performed in case of missing LRTL banks, and in the Runend? I am surprised to see that this change has been made in this way. There is no mentioning of this in the Logbook in 301, so I assume that also the Run coordinator and the Technical coordinator were not informed. There was no mentioning of this change in the DQ meeting last Tuesday, moreover Vladimir Andreev stated that the LRTL bank and the coincidence method values stay unchanged, so that all offline software is unaffected by the recent development in the single photon method applications. And it was also not said anything in this mornings 0900 meeting, at least not what I could hear. A change in this manner, without informing the rest of H1 and without discussing possible offline effects, is not good style. My suggestion is therefore: Keep the LRTL bank values unchanged, but add the correction factor, since it can be interesting later to have as cross-check when the offline integrated luminosity is calculated. One can meanwhile think of a possibility to keep track of this value. Now it just disappears on the TCL tapes (and Lumimon tapes), there is no storage of these values in the database. For this, one would have to change the TCL job, though. I am sending this letter as copy to a number of people, since I think that any change in the luminosity measurement and its storage is impor- tant and should be made known beforehand. There are several suitable places to suggest and discuss such things, e.g. today in the H1 meeting (during which the change was apparently made!). I hope you will follow my suggestion above, at least till the questions about the TCL job corrections in the LH1R and LH1T banks have been cla- rified.

But opinion of our group is - this solution cannot affect to any offline tools for Integrated Lumi calculations. After Tuesday HERA made set of Lumi RUNs with very low ET acceptances and difference between OnLine Integerated Lumi and OffLine Estimated Integrated Lumi could be reach more then 30%. So we back to old release. Unfortunately (or fortunately) no one Lumi RUN was got with new release (it would be good test).

Actually, my suggestion was not exactly that. What I think is the best, is to keep the Integrated Value in LRTL as being given by the Coincidence method, but at the same time add that new word, 241, and register in this word the correction factor. Thus, just keep the factor, but NOT multiplying it on the Integrated Luminosity value. Then one can monitor this factor (e.g. in the TCL job) and indeed learn something maybe. By the way, is this factor calculated all the time, i.e., is it changing from one LRTL to the next LRTL?

Fomenko" Subject: Re: LRTL changes Hello, Dear Jan, Your suggestion to keep only correction factor will not bring any new information at all due to this factor is calculated from some data from LRTL and LUMM-banks. But in case of big and fast ET acceptance changing the later offline correction Integrated Lumi at H1DataBase as seems very complicated and not enough accurate. For example there is not enough statistics of S91-events to make correction sufficiently often (minutes,hours). If correction factor would be too wrong (as last experince shows - it is not so) than it is possible to back to original (old release) values with enough simple algorithm. Last remark - to keep at H1DataBase the more correct value of Integrated Lumi is better then to correct later all Data Base Integrated Lumi values on enough large value and (as seems) with not enough accuracy. You are right that correction factor is permanently monitoring at H1Lumi OnLine system and could be different at each new LRTL-bank. ----------------------------------------------------------------------- Date: FRI, 12 JUL 96 13:40:29 +0200 From: Jan Olsson To: "A.M. Fomenko" Subject: LRTL bank changes Jan Olsson H1 Collaboration DESY F11, Notkestr. 85, 22603 Hamburg 52 Phone (49) (40) 8998 3138 mail address: F11JOL@dsyibm.desy.de CC: Soloviev, Levonian, Gogitidze, Fomenko, Straumann, Biddulph Hello Yuri, and thanks for telling me about the proposed tests of the new LRTL bank format. It seems however that you have missed the point concerning the LRTL bank changes and their consequences. I had outlined them already in my letter yesterday: - The LRTL bank is monitored in the TCL job and its values of integrated luminosity are transferred into the LH1R and LH1T banks, which are stored in the Database. - In case of missing LRTL banks, and for the last seconds of a Run, where the LRTL bank is no longer available, software of S. Levonian calculates a correction, which is ALSO added to LH1R and LH1T. It has NOT been verified, or even discussed, that these corrections are com- patible with the new, Single Photon Method, integrated luminosity. - Therefore it is NOT, repeat NOT, equivalent to store in LRTL now in- stead the Single Photon method values in the same place as previously the Coincidence method values. - My proposal is different: Keep the Coincidence method value in its usual place, but ADD the continuously changing correction factor in the new word 243 in LRTL. With this factor we get new information with which we can later make cross checks in the offline calculations of the integrated luminosity. - It seems that your only argument for overwriting the coincidence value with the single photon value is that with this we will store a more correct value of integrated luminosity in the database. This is not a good argument. It does NOT matter now if we store more or less correct values of integrated luminosity in the database. The integrated lumi- nosity will be used when we do quantitative physics with the 1996 data and this will only start in end of 1996, after careful offline calib- ration of all H1 detector systems. - Important now is to store integrated luminosity values in the database in such a way that they remain fully compatible with the existing software. I remind you that this is software which has been carefully debugged and is used in a multiple of ways. This software depends in complicated ways on the LH1R and LH1T, and this software has a scope far outside of the lumi group alone (ex. M. Fleischers HV correction tool). Any change in the LH1R and LH1T banks must be publically and thoroughly discussed, before changes are accepted and installed. - For this reason I also find it completely out of place to make remarks of the kind "During Lumi RUN# 1002 again was fixed very low ET-acceptance and again S.Levonian's tools wrote into H1DataBase Integrated Lumi value which less then real value on 25-30%. It is pity. Let's wait of some official decision." As I stated above, it is NOT important to be more correct, it is im- portant to be backwards compatible! - The Single Photon method data is available in the LUMM bank. Your group should think of software to store also these values in the same way as is now done for the LRTL data in LH1R and LH1T. This would mean that the data is stored in new banks, which could also have the same structure as the LH1R and LH1T banks (call them e.x. LH2R and LH2T). Note that it is important to store also the correction factor from LRTL word 243, thus the LH2T bank should have one more column than LH1T. With this data, we can in the offline calculations later evaluate the true differences between the Coincidence and Single Pho- ton methods, and also learn something about the systematics in the previous years determinations. - With the storage of LUMM data in LH2R and LH2T, it seems much more reasonable to store the correction factor (which you propose at the end of LRTL) instead in the LUMM bank! Then all data going into LH2R and LH2T come from the same bank, with the same time stamp. - I find it troublesome that this discussion is now carried out via letters. There are many people involved in this matter, and with mails it is not sure that they all get informed. I suggest therefore that there will be some meeting called for this matter, with all involved people. The integrated luminosity is vital to the physics analyses, and after all, these analyses are the reason for doing all this work with the H1 detector. - H1 is a collaboration of people, working together for a common goal, namely to have physics analyses which are correct in all details. The word collaboration means working together. And working together can only happen successfully if communication is cared about. I find it really outrageous that such important changes happen in secret, only to be discovered by chance, without any notice to Shift leader, Run Coordinator, Techn. Coordinator, etc. Not even a written notice in the official logbook of the experiment! This is not how collaboration work should be done. - I hope I dont offend you with speaking clear words. I wish to express my high respect for the work your group is doing, at all times of the day and night. The latest addition of the Single Photon method imple- mentation will help to reduce systematic errors in one of the most im- portant quantities that we measure. Please dont get the impression that I am against this method. Only, it should be integrated with the rest of H1 data treatment in a sensible way, backwards compatible. - The Lumi logbook (F11LEV.H01.LUMI.LOGBOOK) contains today a misquota- tion: Fomenko has written (but you were at the meeting!) that " Today it was proclaimed at H1 Morning Operation Meeting that BOS- structure errors which was found at beginning of July at H1 Data Flow at which had been appeared not so often but permanently are connected with 4,5 Branches not with our 10th Branch." I did not state anything like this in this mornings meeting. It is a fact that Branch 10 continues to produce BOS errors, and in fact the only ones last night came from Branch 10, see the error print below. I have talked with Igor on Monday morning about how to trace this er- ror, and how to establish that it is indeed Branch 10 that produces the error and not the following Branch 11. I proposed to change the bank number of all banks starting with "L", and to write the number of banks from the Lumi system in this place. In this way one can see if all banks in each event are included in the error print, and if the corrupt bank (which has unreadable name) belongs to the Lumi data or to the next branch. The change in the frontend software should be simple to implement, and I hope it will happen soon, since without Branch 5, it seems that most of the BOS errors come from Branch 10.

It is important (as seems) due to Levonyan's tools are recalculating Current Lumi Values for each LRTL bank before accounting it for recalculation of Integrated Lumi. As I knew today at Levonian's tool it was installed 32.38 mb value which was right during very long period from 21.03.94 but not at this year. 26.06.1996 ----- OnLine ---- H1KFOM --- OnLine Programs Development ....... Changings were connected with updating of visible cross section value for ET&PD-method of Luminosity measurements and ... New value of BH 'visible' cross section is 34.47 mb. This value was calculated by V.Andreev with zero tilt and zero beam offset beam condi- tions. Before today the BH 'visible' cross section was 32.38 mb and was set into OnLine-environment at 21 March 1994. A.Usik promised to change this value at his application too. Changing of this value is connected with new ET position at this year (more closely to e-beam - see message of Yu.Soloviev from 15.04.96). ..... New releases are working before H1Run 144392. ... 07.07.1996 ----- OnLine ---- H1KFOM --- OnLine Programs Development ..... Changings were connected with involving of new default value of bremsstrahlung 'visible' cross-section for ET&PD Rate Method of OnLine Lumi Calculation. Value 34.47 mb was changed on 29.68 mb. Value 29.68 mb was produced from analize of last H1Lumi Dedicated Runs (147087-147094) data by V.Andreev. This value shows that e+beam offfset for existing HERA standard operation is not zero. ...

There are a lot of decisions, for example: There is Usik's application (made only for expert using during attempts of debug Photon Arm Lumi Calculations showing for HERA-team). For example this application can run at H1Lumi MacII and at MacII at LPI Office Number 2 (room 125). This application shows Lumi, Specific Lumi calculated with coincidence method without cross-section correction on ET-acceptance changing ('old' manner). In principle simultaneous showing of windows from both Usik's applications (Coincidence(non-corrected) and Photon Arm) is possible at HERA MacII. Minimisation of differencies between both Lumi or (better) both Specific Lumi means finding of optimal ET-acceptance. And supporting of more or less permanent differencies or permanent equal values means keeping of more or less stable ET-acceptance during Lumi RUN. As seems there are no large problems to install mentioned application at HERA MacII (name of this application is H1_Lumi_c, ordinary apllication has name HERA_client). We have only to decide what we shall show for HERA-team. > 2.

Lumi group proposes to change ET*PD bunch rates and ET*PD total rate by correction factor related with ET-acceptance changing. It means that in LRTL-bank we can see after correction 'TRUE' ET*PD-rates which should be used for CONSTANT Sigma_visible at TCL-routine (LH1RU) which is used for Integrated Lumi writting into H1DataBase. And CorrectionFactor we proposed to write into LRTL-bank for poossibility of any off-line manipulation with it for any goals (for example more accurate monitoring of ET-acceptance for physics or for removing of this OnLine Correction Factor from Current Lumi (instantenous) value and from all Intergrated Lumi Values if it is needed what is not obviously).

LRTL-bank bunch rates and total rates are connected with ET&PD triggered events (but corrected on ET-acceptance). Lumi values which are calculated with different digits (methods) must be nearly the same (if there are no mistakes at calculations) and at this case really 2 banks will show almost the same values. > 7.

It is really so that last changing of BH 'visible' cross-section was made during (in the middle of Run 147607). At our H1Lumi LogBook this fact is wriiten. We agree this is bad style of work.

Remark: Sigma = 64.01 mb was determined for PD-threshold value at last H1Lumi Dedicated Runs (147087-147094). Sigma = 65.523mb was defined for PD-threshold value at first this year H1Lumi Dedicated Runs (144729-144734) and it was involved into OnLine Photon Lumi Measurement at 02 July 1996 (see LL13). > > ACTION ---> Jan Olsson, change TCL-job, subr.

Mentioned Off-line Correction is made not for ET&PD-method itself but for Integrated Lumi values which are written into H1DataBase. At our proposal (as seems) we shall write into H1DataBase more correct Integrated Lumi values (with accounting of mentioned beam movements) if mentioned correction will be not removed with TCL-job. We expect that for our proposal this year OffLine Correction will be not so significant as at previous one. And (moreover) if ET-acceptance will be not stable during more or less long time periods (for good statistics of S91) it would be difficult to make OffLine corrections. > > PRO A.

Double presence of Correction factor for ET&PD Method of Lumi calculation is good only for cases LRTL-banks disapearaing from H1DataFlow. At this case Correction Factor for any manipulations can be get from LUMM-bank for example although Correction Factor has not concerning to LUMM-bank variables calculations (only as spare box). For any case it would be possible to make 3rd spare box - at LRTN-bank - due to importance of this variable. > Compare also the discussion about the LRTN bank in the following > point 12. > > What should the 8th column in LH2T be used for?

Mean Effective Photon Arm Energy1(MeV) From this value it is possible to calculate Your mentioned correction factor for Lumi calculated with Photon Arm Method. This correction factor can be used both or BH-cross section correction ( 65.523 mb) due to PD thresholds changing or with inverse value can be used for correction of Lumi value calcualted with Photon Arm Method with using of Sigma_0= 65.523 mb. Some simple expression exists. As seems more reasonable to put first Correction factor (on ET-accepance) into LH1R and second one (on PD threshold changing) into LH2R. It is logical, because ET-acceptance Correction factor has nothing common with Photon Arm method Luminosity data. > ACTION ---> Lumi Group: Change LUMM bank to include 2 corr.factors > Change LRTL to contain 1 correction factor > (but keeping Coincidence data in this bank) > ACTION ---> Jan Olsson: Develope software in analogy to LH1RU and > LH1RS, for storage of LUMM data in the new > banks LH2R and LH2T. > > Clearly, it would be nice to have in LH1T also the correction factor > from LRTL.

From 1994 at H1Lumi Monitoring tools there is some tool for evidence of Relative ET trigg accept (made by I.Sheviakov). During enough long time history it was found that this value was more or less stable and it is understandable why. At 1996 year situation was changed and namely due to prepared earlier tools it was possible to 'make' mentioned ET-acceptance correction factor. For example at our old H1LumiLogBooks it is possible to find some lines aat Lumi RUN summaries which are issued from I.Sheviakov's tools. For example: cite from LL9: ".... 18/07/94 ----------------------- H1KFOM --- Lumi RUN# 502 ....

Sincerely, Igor Sheviakov,Vladimir Andreev,Yuri Soloviev and Alexander Fomenko ----------------------------------------------------------------------- Date: Sun, 14 Jul 1996 17:29:47 +0200 (METDST) From: Serguei Levonian To: "Jan E. Olsson" , "V.F. Andreev" , "Yu. Soloviev" , "A.M. Fomenko" , Nelly Gogitidze , "I.P. Sheviakov" , "A.P. Usik" Subject: LUMI-96 and beyound Dear colleagues, it was fun to follow recent discussions concerning lumi business in logbook and via mails. I would be really interested to participate, but unfortunately I have zero (literally!) possibility for that. I should say unambiguiously now, that I has left this field in favor of other obligatories within H1. This was announced (to our group) ~1.5 years ago, and after that I tried to make as smooth transition as possible. I can (and will) act at the "consulting and assistance" level whenever it will be useful. However the real work should be done by you. Here below I tried again to summarize several problems, as I see them. There is however nothing new: all this I keep saying since years... Perhaps it is too long and boring -- sorry for that. 1) There is a real difference between luminosities in H1 and ZEUS IP. This difference in average is 8-9% (unless ZEUS is doing "secret" and significant corrections to their online values, which I don't believe). Evidence: a) beam scans (after offline corrections of their results) b) average difference between best online L_sp in both IP's during 93-95 c) stable conditions (L_sp) in ZEUS IP versus typical "drifts" in H1 (visible by any method, from online trigger rates) d) a good agreement (within 2%) between F2(H1) and F2(ZEUS) 2) It is known from the beginning of HERA, that e-tagger acceptance is strongly dependent on the e-beam optics. Nothing QUALITATIVELY new has been observed this year as compared to 1995. The statement, that the machine group is unable to tune and keep (withing typical limits of 93-95) the tagger acceptance is -- to my mind -- not correct. Evidence: similar "bad" behavior in the beginning of the last year: H1 runs dL(Online-offline) Comments difference 105288-106568 30% See logbook (LL12, 08.06.95) 110896-111503 22% fig.11 (H1 note 02/96-471) later on +-5% -"- Explanation: the main effort now is NOT a tagger acceptance for gamma-p physics, but optimization of general background conditions (SPACAL, F-muon, trackers) leading to frequent exercises with collimator settings, beam scans etc. (in addition to usual problem in understanding general machine behaviour at the beginning of new lumi running). My expectation is, that in a longer term everything will be stabilized approximately as it was previousely, i.e. +-5-6% difference between the two methods (in average, there might be -- as it was in the past -- larger local discrepancies, esp. in the beginning of lumi runs). Already this year (as follows from the Run Coord. reports) HERA people were able to reproduce predictably the beam orbit during bgr.tests. 3) Our main aim (as I see it) is to guarantee under all sircumstences a correct L value for physics (withing controllable systematics). This implies correct and suffisient LUMIMON data for offline analysis. These data by the way, if rates are properly tuned, also provide the possibility to measure a real e-tagger acceptance for gamma-p physics with sufficient precision. As soon as this is the case -- I don't care about online/offline difference (sorry to say that!) Therefore, I tried to describe all (sometimes unnecessary long) details of the procedure, which was (successfully) used so far for that purpose. I also tried to transfer my knowledge, and I believe, that Nelly is able to continue this line in future without my assistance. Moreover, in principle everybody with a minimal H1 analysis experience should be able do this, following H1 note 471. Andreev should be able to define acceptance for taggers. We discussed the procedure many times, it is now also briefly described in www-pages, and all necessary software is in his hands. 4) The online LUMI group is in a more difficult situation. They have to provide (the order reflects my personal priority) - fast and reliable monitoring of the beam conditions, - fast and reliable possibility for adjusting the best L_sp in H1, - reasonable estimate of the ABSOLUTE luminosity (trying at the same time to be not too much below L_sp in ZEUS area!) - all the infrastructure for the "publicity". To me, the task #3 is least important. It has mostly political impact. Unfortunately, the experience shows, that politics often dominate at DESY. (To discuss the reasons is beyound the scope of the present mail). The "political solution" of task #3 is however very easy: use online a low (say by 20%) normalization value for the visible cross section. It is especially justified in the situation, when one is forced to change this value each day (or each week) as if was recently. As long as Lumi for physics is correct, absolute online Lumi is of secondary importance. (Don't take this as my proposal: it is just an illustration, somewhat emotional though). The first two tasks from the list above are vital indeed. They allow to minimize time (and "tax payer's money", J.O.) which is lost for physics (lumi tuning), and to achieve really best possible L_sp (not faked by acceptance effects etc.) even if its absolute value is not correctly estimated online. For me, the latter reason -- and only this -- is a motivation to change the online method from the coinsidence to a single photon rate. It was suggested to try this new method already in 1994, but that time it was not supported. For me there is no surprise (as I mentioned above) concerning eventual big differences between the two measurements. This is because I know about this difference from experience (doing offline corrections, and observing sometimes significant discrepancies). What came as surprise for me is, how quickly our "online apologets" of the coincidence method gave up and went to "a new religion". One has first to collect enough information and to learn a bit more on the new method (especially under more stable and typical running conditions) before making backward incompartible changes. 5) "Technicalities". I am old and conservative man, and I don't like frequent changes. Especially changes in BOS banks. For me "the modularity" is one of the most important principles to follow in a complex software. Modularity means, that all your modifications are not visible for the outside world (or better to say: not affecting the s/w of this world). The good system should be modular at all levels. I.e. in each of the blocks below. +------+ +------+ +------+ +-------------+ | Lumi |___..___| Lumi |__..__| Lumi |______| The rest | | DAQ | | farm | | offl.| | of the H1 | +------+ +------+ +------+ +-------------+ Since we did not manage to make such a good system (to clever design bank formats in particular) I tried at least to make "The rest of H1" independent on our internal problems and changes. We had already several such (big and small) modifications in the past, so the present situation is not really new. In practice it implies, that as soon as the decision is made to add/delete/ change something in, say, left block, all the following LUMI s/w has to be properly modified BEFORE (!) you switch to the new configuration. Violation of this basic rule may (and will!) lead to unpredictable consequences. This MUST be avoided. And this was a mistake in the last "movement" with LRTL/LUMM formats. The reason -- as usual -- a lack of communication between online and offline LUMI, and at more wide level: between LUMI and "the rest of H1". To provide such a communication was one of my most important tasks in the past. Now it has to be done by somebody else. For that it is important to follow closely the "life" in both "worlds": LUMI and H1. My attempts to prepare a good substitute for that had only very limited success (as it is clear now): nobody from LUMI experts had wish and time to participate in H1 analyses at serious level, neither anybody from "H1 world" familiar with the analysis needs expressed a wish to learn deeply LUMI business. Still: it is never late to start, and I see good candidates in both sides. The best would be, that those who initiate the changes (from online side) would also support a basic offline LUMI tool. Then he/she will think twice before doing frequent changes. But this is perhaps not realistic. So the only solution -- combine the efforts and be cooperative, as Jan O. already suggested. Good luck and high and stable lumi, Sergey P.S. When you will change LH1RU/LH1RS routines withing TCL job environment, don't forget to use identical new versions offline (I mean, that when sometimes TCL crashed, or stopped -- it happened that for several runs lumi info is not written to DB. In past these situations were corrected by submitting offline jobs creating LH1R/LH1T banks from TCL files). ----------------------------------------------------------------------- Date: Sun, 14 Jul 1996 20:44:51 +0200 (METDST) From: Serguei Levonian To: Alexandre Fomenko Cc: "Jan E.

This means, that ET*PD corrected rates in LRTL are not 'TRUE', but just normalized to a single PD (which in turn may be wrong sometimes, who knows in advance?) Anyway, keeping the correction factor in the bank makes possible the reverse calculation, so in general it seems to be safe, up to the bank losses. > > It would be good if HERA keep more or less stable ET-acceptance as it was > at previous year. > In principle more detail and more accurate evidence for the beam movements > at this year can present mentioned correction factor: > 241 CORRLUM I 0 +INF !

As it was also (may be not as strong) in the beginning of the last year. More importantly: there is no error whatsoever in the offline INT.LUMI. ----------------- related to the ET acceptance. By definition. So: "most important systematic error at Lumi Measurements" should only refer to the ONLINE Instantaneous Lumi, which we never even attempted to correct offline. > And (moreover) if ET-acceptance will be not stable during more or less > long time periods (for good statistics of S91) it would be difficult > to make OffLine corrections. > ==> What is (always) true, is that we need good S91 statistics, especially if conditions are very unstable. Instead, as I see from present LUMIMON tables, we have as seems less S91 per/nb-1 than it was in 1995. Too bad if so... But once again about offline Lumi. It is not possible (and never will be) to correct every online lumi measurement. However it is always possible (and with as better precision as more s91 events are available) to calculate CORRECT (within quoted systematics!) INTEGRATED LUMINOSITY for ANY given data sample. Note, that so far we did not attempt to do so (except for the last total gamma-p cross section measurement on the basis of dedicated 1994 data) but in principle it is possible. Independently on any ET-acceptance variation, or even if ET will fall down to the tunnel floor! (No, that last situation is not acceptable: we still need ET for precise calibration of overall system, sorry). And in principle, I believe, that for every physics study, which vitally depends on precise luminosity determination, it must be done, as we did for sigma-tot. The procedure is very simple: a) we get selection criteria, used in the particular analysis (from PWG): run range, detector configuration required, all other cuts used. b) we apply the same (identical) criteria to our s91 sample (from LUMIMON) and calculate directly the integrated luminosity of such selection. Full stop. This way we dont need online L measurement at all. And systematical errors are minimal. > > There is of course another way, suggested by Phil: Go back to the > > Coincidence method for optimizing luminosity! > > ==> This is, by the way, what was originally proposed by me after discussion with Sheviakov last year. Since also PD-rates are often affected in the beginning of LUMI fills (via threshold instability due to high rates), it was suggested to use ET*PD for the first 15-20 min (until LUMI is not adjusted and Lumi run is declared) and then switch to PD-rate. But this was not accepted, as too complicated procedure. However, if both rates are delivered to HERA control room (displayed) they can decide themselve what to use in which situation for optimal result. > > 11.

Although it may be the best in terms of "safety" (to keep as much as possible information), I foresee a lot of possible confusions at various levels (and the far from LUMI itself the more confusions).

Cheers, Sergey ----------------------------------------------------------------------- Date: SUN, 14 JUL 96 21:01:06 +0200 From: Jan Olsson To: "A.M. Fomenko" Subject: Further comments on LRTL content Jan Olsson H1 Collaboration DESY F11, Notkestr. 85, 22603 Hamburg 52 Phone (49) (40) 8998 3138 mail address: F11JOL@dsyibm.desy.de CC: Fomenko,Soloviev,Sheviakov,Andreev,Gogitidze,Usik Dear Sasha, Yuri, Igor and Vladimir, Thanks for your comments which I just received. I had in fact already talked with Phil, after receiving comments from Sergey and Nelly. If you dont mind, I will try to summarize. But let me first apologize for some misunderstandings, which you have been friendly enough to correct, and for making me understand some things better. My main misunderstanding: It is NOT PD results you intend to write in the LRTL bank, it is corrected ET*PD rates, corrected in such a way that the luminosity and integrated luminosity calculated from these rates are independent of the Etagger acceptance changes. If calculations and cor- rections are done correctly, then the results will be more or less equal to the results from the PD rate calculations. Thanks for clarifying this in some detail. One question arises: With what means is the correction factor calculated i.e. from what rates? A tool of Igor is mentioned by you, existing since 1994. What exactly does it do? What systematics are involved in the correction factor calculation? Concerning sending copies to people outside the Lumi group: This was done only to Phil and Uli. They HAVE to know what is going on in the experiment. My sending copies to them was motivated by your changes in the online software without telling anybody about it. I think you agree with me now that this is bad practise (like changing things during the ongoing run), and I think you realize the importance about informing all responsible people about any changes you undertake. We have many mee- tings for this. So, this was my reason for immediately informing Uli and Phil. With proper communication before changes are decided upon, a lot of mail and misunderstandings can be avoided. Let us continue in this spirit. You ask excuse for English language. This is sometime a problem, I agree and also on my side, but usually we can solve problems of understanding with some iterations. Language should NEVER be a reason for not communi- cating at all, this is my firm belief. If necessary, I will learn better Russian...! Let me pass the various points of my last letter, and see if we now agree in understanding: 1-5. About providing signal to HERA for Etagger acceptance optimization and stability. I understand from Phil, and from your letter, that this is being done, and that the ET*PD rate will be given, in fact the rate for luminosity with Coincidence method. This will be in addition to the Single Photon luminosity signal you already deli- ver to HERA. There is no comment from you on the mail from Sergey Levonian of this afternoon. I agree with him that what we see now is the start up of HERA 1996, with large deviations during the running in, and that these deviations will later be small, when HERA has stabili- zed with respect to our background rates (chambers, SpaCal hot spot, etc.) and we enter the phase of production running this year. Surely you also agree with this? 6-8 I think we now have common understanding (see my remarks above) about the corrected ET*PD rates. And then it is also clear that the SIGMA in LH1RU has to be the ET*PD cross section. This will have a value around 30 mb, when stable conditions enter. Thanks for clari- fying this important point! 9. I propose that mistakes in the bank descriptions are immediately sent to Uli Martyn. You should do this, not I. (concerning LRTN) 10. As soon as stable conditions enter the ET*PD measurements, and this will happen as soon as HERA get information from H1 which allows to stabilize Etagger acceptance, there will be NO NONSENSE in the LRTL bank data. It will contain data of the same quality as in previous years. Your comments to the PROs and CONs have no good argument against my proposal: * Keep LRTL rates as they are, namely as the direct measure- ments from the online! * Add the additional information (the "correction factor") in each LRTL, but WITHOUT overwriting the original rates! * Leave ALL corrections to the offline analysis! Raw data constitutes measurements! These should never be corrected to some ideal configuration during the measure- ment phase, in a dynamic fashion. Such corrections belong to the offline analysis, and only there! * The correction factors, calculated online, are to be con- sidered as additional raw data information. They are to be suitably stored offline. But NOT by multiplying them onto other raw data information, which already has a well- defined and debugged offline treatment. * You have yourselves declared that you agree to being back- ward compatible with previous physics results. Then you should not advocate changes in LRTL which will make the new results NOT immediately compatible with the old ones. Therefore the correction factor should only be added to the bank, but the rates should NOT be corrected. In this way we stay backward compatible, as is also your wish. Your proposal to overwrite the rates with corrected ones, does create a lot of additional work for anyone who wants to do this backward compatibility check. It is clear from all discussions and also from your comments now, that your arguments for online correcting the measured rates, are only cosmetic nature: There will be less difference between online and offline results in the integrated luminosities. I agree fully with Sergey Levonian that this is really 2nd hand. Changing the con- tent of bank definitions, putting offline software in jeopardy, for such petty reasons, is irresponsible. It should not be done. Compare the comments of Sergey Levonian to such changes! 11. Be very careful with what banks you are talking about. LH1R and the proposed LH2R are GLOBAL banks. There is absolutely no way to in- clude the correction factors (one every 10 seconds!) in these banks. The correction factors belong in LH2T, and ONLY in LH2T. I have ex- plained in great detail why they cannot be put in LH1T. And to put them in LH2T, they need to be present in LUMM bank, which will feed the bank LH2T. No more argument about this, I hope. Your misunder- standing, expressed in your comments to point 11, should now be en- ded. Concerning the 2nd correction factor, , it seems that it can be calculated from the other data in LUMM. Thanks for this information. My suggestion will then be to calculate the correction factor, and to store it in column 8 of LH2T. As I already explained, both fac- tors, for ET*PD from LRTL and for PD from LUMM, will have to go to LH2T, since LH1T cannot take the first factor. Although this would be logical, it is not possible. 12. Sorry for being somewhat sloppy in numbering words in the BOS banks, sometime including miniheader, sometime not. But you have understood what I mean, in every case. I should be precise about what I mean with "changing a bank". There are 2 ways to change a bank: To change the format: Very dangerous, usually there are immediate consequences with program crashes. To change the defined content of the bank: Most dangereous of all, since it often has no program crash as consequence, and the real damage will be apparent only much later. Indeed, the change may first appear to be successful, for some limited purpose, and the real consequences are unknown to the person who makes the content changes. I can give you examples from the HEP world, where such changes have led to the recal- ling of published physics results (and in at least one case it meant the end of HEP career for the person who had the bright idea). Your statement: "LRTN will not change" is then followed by the statement that the CONTENT will of course change, since the Luminosity is calcu- lated from those rates which you are going to "correct" online. This is a bank change of the 2nd type, which I described above. So, I repeat: DONT change the raw rate information in LRTL (and LRTN, by definition then, since these rates are used for calculation to LRTN). 13. Alright, you had thought about it. It should have been more publicly discussed (who reads this LUMI.LOGBOOK outside your group, except me?) But your attempt to make the ET*PD method "more correct" is wrong. Overwriting the MEASURED rates, with online calculated CORRECTED values, is NOT a better measurement, it is a faked measurement. You propose to replace the real measurements with faked measurements, for cosmetic reasons. But, the online calculated correction factors, these constitute a NEW, additional measurement, and they should be made available in the data stream, as NEW and independent data, to be used in the offline analysis for estimating the true integrated luminosity, to be used in physics analysis. 14. You say, that you still cannot find any reason for NOT overwriting the measured rates with corrected rates. I hope, that the additional comments above, plus the detailed comments from Sergey Levonian (who has a very long experience in the offline business, and who wrote most of the offline software, if not all), will help to bring the needed reasons for NOT changing the data definition in LRTL. LRTL should contain MEASURED Rates, NOT corrected ones! Concerning "disadvantage" and 2 methods. Actually, nobody said it was a disadvantage. Only, the impression came up that it is necessary to make the 2 measurements equal, equal in the sense that they give the same re- sult already online, so that nobody sees the differences, which are now due to changing Etagger acceptance. I still insist, that all important changes in the Lumi system should be kept notified in the H1 Logbook, available for everybody in 301. That the Lumi group keep their own logbook is of course right, and all other detectors in H1 also have such local logbooks, but ALL important changes must be made known to technical coordinator, run coordinator and shifts, thus they MUST be entered in the central logbook also. This is of course true for all subdetectors in H1. And apart from this, important changes should be voiced publically in the H1 meeting (I recall that the latest LRTL change was actually done during the H1 meeting, when most of the collaboration was discussing the content of new physics papers), and, of course, in the DQ meeting, if these changes concern the data quality. This is the end of my comments. Are there still misunderstandings? I see now only one question, put above, namely about the origin of the "cor- rection factor". Are we still disagreeing on the changes of data definitions in LRTL? Do you still propose to overwrite the LRTL measured rates with corrected rates? If so, then we should have another discussion around a table, also involving Phil again. And it would of course be interesting to hear Sergey's opinion on this question. It seems that we actually agree on all other aspects in this problematic now, only the LRTL content is under discussion. Thus, the question about the correction factor remains since it is not clear to me how it is made, and what systematic dangers it is exposed to? Again, many thanks for detailed information! Warm greetings, Jan PS. I send these comments to all involved members of the Lumi group, and also to Sergey Levonian, since his experienced opinion is much va- lued, even if he has no time now to get involved in the details. And since there was already a discussion with Phil Biddulph, I will let him have a copy too, I hope you dont mind. There is really nothing in this to hide, I think. PS: I just got the latest comments from Sergey, also to my mail from yesterday, and to the answers from Sasha F, Yuri, Igor and Vladimir, which I have answered to above. Thanks for the additional information. Concerning LH2R and LH2T: I have not intended that these banks shall be used for the "standard" offline, e.g. the M. Fleischer tool. But they shall be available for the expert cross-checks, containing the new in- formation which is available. For these reasons, their structure should be similar or identical to the existing LH1R and LH1T banks. But usage: For experts only! PS: Please indicate when sending further mail to whom you send copies. I understand that the following persons are involved in the discus- sion: VA,YS,SF,SU,NG,SL,IS,JO. Who did actually get a copy of the mail that Sasha Fomenko send to me? ----------------------------------------------------------------------- Date: Sun, 14 Jul 1996 22:23:10 +0200 (MST) From: Alexandre Fomenko To: Jan Olsson Subject: Re: Further comments on LRTL content Dobrii Vecher, Dear Jan, Thankyou for Your last mail.

Today after long discussion between V.A.,N.G. and me became clear that Nelly's estimation of Integrated (H1DataTaken) Lumi for H1Runs 147087-147094 shows good agreement with one recorded into H1DataBase (near 7.06nb-1). We know that Integrated (H1DataTaken) Lumi for recording into H1DataBase is recalculated at S.Levonian's tools from LRTL and TCUR-banks contents and with BH 'visible' cross-section 32.38 mb. Precision of Nelly's estimation is 1.6% (statistics mainly). It was made test of all recalculated Int.Lumi at H1DataBase with next procedure. It were got as start points H1DataTaken Lumi values for mentioned H1Runs from Egor's LongTermHistory. These values were calculated for BH 'visible' cross-section 34.47mb and it was made correction of mentioned Int.values on factor 32.38/34.47=0.9394. It was made correction factor for new BH 'visible' cross-section 29.68mb too (for estimation of differencies with off-line method): Run OnLine Factor corrected H1DataBase Factor corrected value (must be at H1DB) (is at H1DB) (if 'real' cr.-section) nb-1 nb-1 nb-1 nb-1 cr.sect-> 34.47mb 32.38mb 32.38mb 29.68mb 147087 0.595 0.633 0.65 0.6911 147088 0.100 0.106 0.14 0.1161 147089 0.192 0.204 0.23 0.2230 147090 0.067 0.071 0.09 0.0778 147091 0.044 0.047 0.06 0.0511 147092 0.083 0.088 0.10 0.0964 147093 1.538 1.637 1.66 1.786 147094 3.827 4.074 4.13 4.445 ----------------------------------------------------------------- Sum 6.860 7.06 7.49 ----------------------------------------------------------------- Some conclusions: 1) Levonian's tool for H1 Integrated Lumi (H1DataTaken) recalculation put into H1DB value on 3% more then ones estimated at OnLine with the same BH 'visible' cross-section. As seems accounting of little peaces of Integreated Lumi at end of Runs (last pieces less then 10 sec.) at this case cannot explain mentioned 3%. There is very preliminary evidence that (may be) at Levonian's tool DeadTime is calculated not enough distinctly (manipulations with 40bit words)but it is needed some time for detail understanding of his algorithm of work with 40 bit integers.At OnLine we have another algorithm (very precise) with absolute accounting of each count at 10MHz counteres. 2) there is difference between recalculated Int.Lumi from OnLine with new 'right' BH 'visible' cross-section 29.68mb (7.49nb-1) and estimated by Nelly with famous OffLine method (7.06nb-1). Difference is near 6% from (7.49-7.06)/7.06. 19.07.1996 ================= H1KFOM === Int.Lumi at Dedicated Runs.. S.L. asked to use as OnLine value more distinct value (from last LRTL-bank). I made it too and produced the next results: (OnLine Integrated Lumi were got from J.Olsson's Run Summaries) Run OnLine Factor corrected H1DataBase Factor corrected value (must be at H1DB) (is at H1DB) (if 'real' cr.-section) nb-1 nb-1 nb-1 nb-1 cr.sect-> 34.47mb 32.38mb 32.38mb 29.68mb 147087 0.602 0.641 0.65 0.699 147088 0.123 0.131 0.14 0.142 147089 0.207 0.220 0.23 0.240 147090 0.071 0.076 0.09 0.082 147091 0.060 0.064 0.06 0.070 147092 0.085 0.090 0.10 0.099 147093 1.550 1.650 1.66 1.800 147094 3.848 4.096 4.13 4.469 ----------------------------------------------------------------- Sum 6.968 7.06 7.60 ----------------------------------------------------------------- 1) Difference between H1DataBase Int.Lumi value & OnLine values is less (only 1.3% from (7.06-6.968)/7.06). S.L. said that algorithm of DeadTime accounting at his tool is absolutely correct. May be this new (little) difference can be explained with something else (partly with early mentioned little pieces of Int.Lumi at end of Runs, partly with little differencies at OnLine/OffLine algorithmes); 2) Difference between OffLine Lumi Estimation(7.06nb-1) and OnLine ET&PD Lumi estimation with cross section 29.69mb became more (7.65% from (7.60-7.06)/7.06). 3) mentioned 7.65% must be explained with something else (with more correct using of ACCC - due to (as S.L. pointed) existing ACCC- -matrix was calculated for beam offset zero and at H1Lumi Dedicated Runs there is real evidence that beam offset was not zero. ACCC-mat- rix for non zero beam offset will be another and enough strongly depends from beam offset value. May be estimated PD-threshold value is more then real. There is some evidence at distribution for PD-sample that PD-threshold a little overestimated. It is possible to wait from V.Andreev recalculations that Int.Lumi will become less then 7.60 mb for both OnLine methods but (as seems) 7.65% too much value for correction.

All events from 1A-sample were collected with similar to previous year DataTaking ET-acceptance. It is seen at ETrec|PDrec energy spectra shapes, Xet/Yet plots. So - for Sample 1A it were selected from M-qua- lity (G-Runs are absent up to now) H1Runs from Lumi RUNs 990-995 (H1Runs 147095-147813): ETPDnVC - 16282 events ETPDVC - 33137 events S92 - 3463 events ET44VC - 8695 events Mentioned events were collected during 65 hours from 05/07/96 21:01 up to 08/07/96 14:04.

The Luminosity Run (the first one after the change which was done) is in progress now. Let us see the result later. The purity of st91 is also good: only less than 2% of events are not reconstructed (or have E < 1 GeV). 24/07/96 =================== === Lumi RUN# 1022 Start - End of Run 1022: 24/7/96 13:24:42 - 18:48:20 Collision time for H1Run - physics: 14:54:11 - 18:48:20 Currents at the begining (mA): Ie= 21.41, Ip= 48.02 max lumi value, (last record): 1.119, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.323, (0.691) mkb-1 s-1 mA-2 collided bunches = 174 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 6 HERA total lumi: 18.53 nb-1 HERA - physics: 13.22 nb-1 H1Run - physics: 9.07 nb-1 H1data - physics: 5.61 nb-1 H1 operation eff.: 68 % , DT corr.: 61 % , Tot eff.: 42 % H1 Runs: 151573 - 151625 25.07.1996 ================= H01GOG === Int.L for runs 147087-147094 I've got a mail from J.Olsson with the listing of the new banks (LH2R, LH2T, LH3R, LH3T), which he has produced only for our dedicated runs 147087 - 147094. The information looks very interesting. For those, who have no copy of this mail, I'll try to explain very briefly what he has done. So, he took the existing subroutines in the TCL job, i.e. the subroutines which create the LH1R and LH1T banks, and adopted them to the LUMM banks instead of LRTL. What these subroutines do: - Time is taken from TSTC and ZTBU banks. In these banks H1 Total and H1 Active time is given in HERA clock units. They are converted to millisec. by E.Elsen's tool MSEC (in H1UTIL). - Bunch currents are taken from bank TCUR. - Rates are taken from LRTL, and with this information (currents and rates) the Current Luminosity is calculated. The SIGMA is still 32.38 mb. The acceptance correction is taken from LRTL word 228. - If no LRTL, the current luminosity is taken from LRTN. - With luminosity and time information, integrated luminosity is calculated and stored in the banks LH1R, LH1T. - The timing information in ZTBU (Run End) is used to correct at end of run for the last information, which is not available in LRTL. The subroutines for making LH2R and LH2T in the same fashion were created. The only difference is that Rates come from LUMM bank (PD1), SIGMA is 65.523 mb since the Single Photon method is used. Banks LH3R and LH3T are absolutely similar to banks LH1R and LH1T, but they were calculated with SIGMA = 34.47 mb, which we used that time online. What I have compared at once, are the values of Int.Luminosity from LH2R bank and calculated offline, using ST91 events: L(offline) ~= 7.1 nb-1 (stat.er.~=1.65%) L(LH2R) ~= 7.4 nb-1 Delta = (L(offline)/L(LH2R) -1)*100% = -4.1% Where could this difference come from? I think, that a few things could contribute: - stat. error (~1.65%) - since for the offline calculation I use an energy cut Egamma(min) > 10GeV, I don't take into account "zero energy gammas" (for this particular case ~2%) - the real cross section could be different from the one J.O. used to create LH2R (65.523 mb) - other reasons? After all, we can see that online (SPM) and offline integrated luminosities are in quite good agreement. But, still there is room for further investigations. 25.07.1996 ================= H1KFOM === Re: Int.L for runs 147087-094 > The subroutines for making LH2R and LH2T in the same fashion were > created. The only difference is that Rates come from LUMM bank (PD1), at LUMM-bank PD-rates are written (not PD1 or PDlow). I wrote to H.U.Martyn mail with this correction but he did not make this little correction at LUMM-bank description. > SIGMA is 65.523 mb since the Single Photon method is used. It is known that SIGMA for H1Lumi Dedicated Runs 147087-147094 was estimated by V.Andreev as value 64.01 mb (with very good precision) So - for correct making of LH2R and LH2T banks contents for this case it would be good to use value 64.01 mb. In principle there is some simple expression for correction of Lumi estimated with SIGMA=65.523mb due to changing of effective thresholds. Subroutines for making LH2R and LH2T banks must be incremented on this correction factor calculation and involving. At OnLine Lumi calculation with PhArmRate Method this correction was involved at 07.07.1996 (see LL13). > What I have compared at once, are the values of Int.Luminosity from > LH2R bank and calculated offline, using ST91 events: > > L(offline) ~= 7.1 nb-1 (stat.er.~=1.65%) > L(LH2R) ~= 7.4 nb-1 > > Delta = (L(offline)/L(LH2R) -1)*100% = -4.1% If You will use more correct SIGMA: (65.523/64.01)*7.4 = 7.57 nb-1 -> almost the same as it was estimated with SIGMA=29.68 for ET&PD OnLineRate method. So - problem exists. Almost the same difference exists up to now. > Where could this difference come from?

As seems - mainly other reasons. There are some ideas at V.Andreev's hands - some evidence on beam offset changings during Dedicated Runs, some evidences that ACCC was calculated not enough correct (there is another Sigma at Xpd-distribution now (more then earlier)) etc. > After all, we can see that online (SPM) and offline integrated > luminosities are in quite good agreement.

Pictures shows that e+'low current' bunch current population produces some 'additional' PD- and ETPD-rates at p-pilot bunches in compare with empty bunches: p-pilot bunches empty bunches PD-rate: Mean=9.76Hz Sigma=4.80 Hz Mean=6.06Hz Sigma= 2.38Hz ET&PD-rate Mean=0.81Hz Sigma=0.13 Hz Mean=0.63Hz Sigma= 0.12Hz i) it were built 2-dimensional plots e+bunch current versus PD Trigger Bunch Rate normalized on 1 mkA of Bunch Current for: a) e+pilot bunches; b)p-pilot bunches and c) empty bunches: - it is seen that at first stage of Lumi RUNs (when beam-gas back- ground is enough large) there are population of statistics at region with Normalized PD Rate region more then 4 Hz/mkA at e+pilot bunches distribution. At last stage of Lumi RUNs when low background conditions achieved there are 'main' statistics population at region less then 1Hz/mkA. - it is seen at p-pilot and empty bunches pictures that there is enough significant noise at PD Bunch Rate (may be ReadOut noise) - which is estimated as 6Hz per bunch. - it is seen from p-pilot and empty bunches pictures that there is mentioned at (h) difference and at Normalized PD Rates too. Values of Normalized PD Rates for 1mkA and 2 mkA e+currents are enough large (due to mentioned ReadOut noise) but for 3mkA,4mkA,...8mkA there are reasonable distributions of Normalized PD Rates around 1.0-1.5 Hz/mka for empty bunches and 1.5-2.0 Hz/mkA for p-pilot bunches. May be this little difference exist due to 'colliding' of low e+ bunches with p-pilot (with enough large currents) bunches. j) it is difficult to make conclusion about real presence at HERA of mentioned measured by HERA low bunch currents but there are some evidences that these low bunch currents produce some additional rates at H1Lumi detectors with more or less reasonable explanation. 15/08/96 =================== T.Hadig === Lumi RUN# 1053 (empty) Start - End of Run 1053: 15/8/96 9:35:34 - 9:42:32 Collision time for H1Run - physics: 9:40:41 - 9:42:32 Currents at the begining (mA): Ie= 7.9, Ip= 59.98 max lumi value, (last record): 0.005, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.002, (0.691) mkb-1 s-1 mA-2 collided bunches = 153 e+(-) bunches = 167, p-bunches = 180 e-pilot b. = 14, p-pilot b. = 27 HERA total lumi: 0 nb-1 HERA - physics: 0 nb-1 H1Run - physics: 0 nb-1 H1data - physics: 0 nb-1 H1 operation eff.: 0 % , DT corr.: 0 % , Tot eff.: 0 % H1 Runs: 155095 - 155095 P.S.

It was found bug at algorithm of H1 Gated & H1 Data Taken calculation (see next message) (a.f.) 16.08.1996 ================= H1KFOM === Int.Lumi at Run 155230 ...... As seems it is found one of bugs at Int.Lumi (H1G & H1DT) calculations at H1LumiOnLine. It was found that at first H1Run of Lumi RUN #1055 (155230) the H1 Gated and H1 Data Taken Lumi values were calculated not correct at OnLine. Reason is at non correct algorithm of accounting Integrated Lumi collected from Start of H1Run up to first measurement of Lumi during this H1 Run. H1Run 155230 was started at 21:47:05 when Lumi was not measured. Lumi Measurement was started at near 22:21 (after near 1900 sec. from H1Run 155230 start). First Lumi measurement put value 4.721mkb-1sec-1. This value was multiplicated on 1900 sec and the result (near 8.9nb-1) was put into H1Gated and with correction on Dead Time into H1DataTaken. It means that it is needed to involve some 'protection' on time period value (not more then 10 sec.). HERA produced Int.Lumi was calcualted correctly. 16.08.1996 ================= H1KFOM === H1 Data Taken Lumi(LUMM/LRTL) It was made some analisis of data from LRTL and LUMM banks (H1 Data Taken Lumi) and there are some interesting facts: Lumi RUN 1046: H1Run LRTL-234 LUMM-732 Difference RunQuality H1DB H1DB/LRTL mkb-1 mkb-1 % -/P/M/G nb-1 difference 154586 87.294 129.839 32.77 - - 154587 260.325 381.841 31.82 - - 154588 139.154 195.912 28.97 P 0.13 154589 489.970 622.641 21.31 M 0.45 154591 355.304 446.608 20.44 G 0.33 154592 327.527 408.373 19.80 G 0.30 154593 2210.470 2757.530 19.84 G 2.04 -7.692% 154594 100.805 123.633 18.46 G 0.10 154599 265.774 327.016 18.73 G 0.24 154600 859.646 1044.510 17.70 G 0.80 154601 3963.160 4859.750 18.44 G 3.76 -5.122% On the first view it means that ET-acceptance had been changed permanently during mentioned Lumi Run from enough low value to more or less reasonable value. But if it so it will be impossible to make some ET-acceptance correction at offline during so short period. H1DB/LRTL Difference calculated as (3.963-3.76)/3.963 = (LRTL-H1DB)/ /LRTL. Remember that BH visible at OnLine (LRTL)=29.68 and at Levonian's tool = 32.38mb. So (1/29.38-1/32.38)/(1/29.68)=0.08338.It is not understandable why H1DB/LRTL difference is another as -8.3%. Accounting of Lumi between last LRTL and EndRunRecord at both cases must be not so large (72 LRTL-banks and 258 LRTL-banks). There are no any spikes at Current Lumi Value behaivour with time at Lumi RUN 1046. May be Dead Time accounting is not the same? 16.08.1996 ================= F11LEV === Comments to previous message Several attemts have been made to explain the things, which are known since very early days of HERA operation, concerning online and offline luminosity determination. However, as I see they were either ignored, or completely misunderstood. Again and again the same strange comments appear in the logbook, which can only confuse those, who is not involved in the analysis. Fomenko keeps writing to the logbook many things (not all important) while avoiding to answer real problematic questions about strange online malfunctioning, some of them being known since 1993 (!!!) and still not fixed yet (see e.g. last mail from J.Olsson about Lumi resetting during the data taking). Once again: 1) Even if ET-acceptance is strongly varying in time it does not influence an offline luminosity determination, based on s91 sample. It is bad for gamma-p physics, because only average acceptance can be calculated, but we have to live with that anyway. 2) The dead time is calculated correctly offline !!!!!!!!!!!!!!!!!! (Although it is not Elsen's tool as Jan said, but mine -- it does not matter -- the calculation is trivial, independently on the number of bits used). Those who have doubts, can check this by comparing DT estimate from online with those stored in the DB (use s/r GETH1L for that. 3) Whenever any difference appeared betwen online and offline values, our online team ALWAYS tend to claim, that the mistake is at the offline side, contrary to the large record of opposite evidences. I don't like this style I must say. Now to the possible explanation of the last discrepancies described in the previous message of A.Fomenko. As far as I know, there has been another change made recently online, which is NOT YET done offline (again, as far as I know). Namely: the definition of the pilot bunches. Compare the thresholds. In "quasi-offline" procedure, which calculates LH1R/LH1T banks going to DB, 3 mkA and 5 mkA are used. If online values are different, this may explain the fact. If it is true - than it is bad, because it would mean that some of the pilot bunches, defined as such online, may contain a little contamination of the collisions from the tails, below the threshold. As a consequence, the e-gas bgr. would be overestimated and the real luminosity became smaller (in accordance with what was observed: online L is bigger on 5%-7.7% instead of the expected 8.3%) That is why I was very reluctant to rise the thresholds. In case of low thresholds one may lose some pilot bunches, but this does not deteriorate lumi measurements (as long as at least several e-pilots remains) -- the value R(ep) = R(tot) - R(pil)*I(tot)/I(pil) remains OK. However, if one label colliding bunch as a pilot, it could change the result significantly! 16.08.1996 ================= H1KFOM === H1 Data Taken Lumi(LRTL/H1DB) I want to add into list of possible reasons of mentioned at previous messages differencies else one: a) at H1Run 154593 it were fixed only 71 LRTL bank (not 104 or 105 as it is possible to wait from Run duration (1053 sec). It is seen from plot that after 5th min after Start Run 154593 something happened (as seems at Farm level) and not all LRTL were retranslated into H1DataFlow. Sometimes 5-6 neighbour LRTL-banks had disappeared. As seems at this case S.Levonian's tool is using data from last LRTL and for Int.Lumi multiplicating on 50-60 sec (not 10). In principle it is source of overestimation of Int.Lumi (and it is understandable why at case H1Run 154593 difference LRTL/H1DB is not so significant at at case H1Run 154601. b) at H1Run 154601 258 LRTL-banks were fixed (as seems no any disappea- red LRTL-bank) - Run duration 2619 sec. So -5.122%(-8.338%) difference (near 3.2%) is 'standard' one. P.S. -It is good and very important that S.L. alived again at H1Lumi Logbook after enough long pause. -It is needed to underline that thresholds at OnLine for bunch currents were installed very long time ago as 7mkA and after this never was changed. If situation so serious as S.L. described I can change mentioned thresholds on recommmended ones (3 and 5 mkA). -Mentioned problems with "online malfunctioning" are new and only similar to problems "being known since 1993 (!!!)". As seems these problems connected not with H1LumiOnLine itself but (may be) with H1CTRIG interface with H1Lumi (something new). Problems are under study during last weeks. P.S.(SL) 1) May be the reason is new, may be old -- it was never explained clearly, what was the reason of Lumi spikes and resettings to 0 in 1993-1994, so it is hard to judge. 2) Since in the procedure of calculating exactly same things (Lumi for databse: s/r LH1RU/LH1RS) there are no such bugs -- it means, that the problem can be solved also online: after all we are using the same Egor's rates from a fast histogramming memory, all the rest is a simple arithmetics for 11 years old kids. 3) I do not argue to modify bunch current thresholds in the online procedure immediately. One has first to study more seriousely and systematically all available data and also all consequences. I just want to point on one additional source of systematical error, which should be considered seriousely. New compared to previous experience is the fact, that so called "empty" bunches this year seem to have in average larger "remnants" (or tails) of the current. Whether or not they are due to real particles -- needs further clarification. - Too low thresholds are safe wrt bgr. calculation, but may sometimes lead to a situations when no pilot bunches are found. At least offline the thresholds 3 and 5 mkA lead to frequently changing # of identified pilot bunches in the last Lumi fills (in variance with 93-95 conditions) - Too high thresholds are dangerous, as they tend to overestimate the background and thus to underestimate L. Since the real life is not so simple and stable, I think, that the procedure of the bunch structure determination should be more sophisticated and flexible than just these two extremes. 4) Finally: what does it mean: "Levonian alive again"?? Life is more than just writing to our logbook. If one would use only such a criterium, than Sasha Fomenko is "Jivee vseh jivyh", while Egor - "h-hm-m" 17/08/96 =================== T.Hadig === Lumi RUN# 1056 (1.0pb-1 H1DT) Start - End of Run 1056: 16/8/96 18:42:20 - 6:11:30 Collision time for H1Run - physics: 19:40:06 - 6:11:30 Currents at the begining (mA): Ie= 31.83, Ip= 51.22 max lumi value, (last record): 0.784, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.297, (0.691) mkb-1 s-1 mA-2 collided bunches = 174 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 6 HERA total lumi: 63.32 nb-1 HERA - physics: 58.07 nb-1 H1Run - physics: 48.32 nb-1 H1data - physics: 2.93 nb-1(corrected by hands from history- 41.93) H1 operation eff.: 83 % , DT corr.: 6 %(86%), Tot eff.: 5 % (72%) H1 Runs: 155370 - 155400 P.S.

H1DB/LRTL Difference calculated as (LRTL-H1DB)/LRTL (-8.338% must be). LRTL/LUMM Difference calculated as (LUMM-LRTL)/LUMM. You can see that all is more or less OK with difference LRTL/H1DB at enough long H1 Runs. Fantastically another ET-acceptance was fixed at 155175 and 155185 H1Runs (more 'good', similar to start of H1DataTaking96). More or less stable ET-acceptance was fixed at 155186-155195 H1Runs. There is some evidence that at last Lumi RUNs ET acceptance became more and total energy resolution (ETrec+PDrec spectra) became better. 18.08.1996 ===== Calibr ==== H1KFOM === Sample 3A Relation Coeff.Set It were selected from 346nd-373th LUMIMON data sets events which are used for 5th at this year 'standard' calibration. Boundary for sample 3A was got as end of Lumi RUN 1055 due to enough statistics collection after plan access into HERA tunnel with HV Off at H1Lumi at H1Lumi Detectors (last item enough significant). All events from 3A-sample were collected with very low ET-acceptance (the same as at 2A-2C-samples).It is seen at ETrec|PDrec energy spectra shapes, Xet/Yet plots. So - for Sample 3A it were selected from G- and M-quality H1Runs from Lumi RUNs 1044-1055.

Official note will be issued a little later. 1) X-beam size at H1 IP is near 1.05-1.06 more than at ZEUS IP. Y-beam size at H1 IP is near 1.02 more than at ZEUS IP. So - "total" H1 "beamsize" is near 1.09 "total" ZEUS "beamsize". And (as seems) it is natural reason of H1Lumi less than ZEUS Lumi on near 9% (what we can see ordinary during long Lumi Run - not at the start of Lumi RUN). 2) During mentioned exercises it was found that maximal Lumi at H1IP is achieving not with recommended near zero but with near +0.8cm. It is needed to discuss this question with somebody who long time ago recommended to work with around zero. Now (at Lumi RUN 1065) I see that HERA works with near +0.8cm at H1IP. 23.08.1996 ====== L4Histos = H01LNS === LR# 1064 Y_PD -> 1cm ======== In the last LR# 1064, the Y_distribution for the PD is shifted to higher Y, so that the mean Y_PD is ~1.0 cm, instead of ~0. cm that is seen at the reference histo. 22/08/96 =============== Gerry Lopez === Lumi RUN# 1065 Start - End of Run 1065: 22/8/96 14:46:28 - 23:26:09 Collision time for H1Run - physics: 15:36:36 - 23:26:09 Currents at the begining (mA): Ie= 38.22, Ip= 67.34 max lumi value, (last record): 4.988, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.43, (0.855) mkb-1 s-1 mA-2 collided bunches = 175 e+(-) bunches = 190, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 5 HERA total lumi: 103.06 nb-1 HERA - physics: 99.79 nb-1 H1Run - physics: 84.63 nb-1 H1data - physics: 66.3 nb-1 H1 operation eff.: 84 % , DT corr.: 78 % , Tot eff.: 66 % H1 Runs: 156165 - 156189 23/08/96 ========== Phillip Biddulph === Lumi RUN# 1066 Start - End of Run 1066: 23/8/96 5:17:29 - 8:40:21 Collision time for H1Run - physics: 6:18:00 - 8:40:21 Currents at the begining (mA): Ie= 42, Ip= 65.43 max lumi value, (last record): 5.815, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.422, (0.855) mkb-1 s-1 mA-2 collided bunches = 174 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 6 HERA total lumi: 55.16 nb-1 HERA - physics: 48.54 nb-1 H1Run - physics: 34.01 nb-1 H1data - physics: 23.52 nb-1 H1 operation eff.: 69 % , DT corr.: 68 % , Tot eff.: 48 % H1 Runs: 156224 - 156238 23.08.1996 ===== Calibr ==== H1KFOM === ET44 Rel.Coeff.Set Sample 3B Today it was defined Relation Coefficients Set for ET44-channels at events from H1Runs 155370-155770.

In the previous night I have updated 1996 LH1R banks in the master database to bring them to the real online coincidence measurement results. This means: lumi was renormalized globally by the ratio of the cross sections: for the run period 144392 -- 147606: * 32.38/34.47 for the run period 147608 -- 156516: * 32.38/29.68 Starting from the run 156517 the cross sections for the coincidence method used online and in LH1RU routine are the same (29.68 mb). It was done in order to make easier an interpretation of the future offline corrections to online measurements, and to avoid confusions with two different "online" values for the same method. As you know, since few days H1 went back to the coincidence method for the luminosity optimization and display. During first day both methods gave approximately the same result (+-3%). This night however, the difference was up to 10%: L_sp = 4.0*10^29 (coinc.) and = 4.4*10^29 (single photon). Second remark. New position at = +0.8 - +1.0 cm, claimed to be better optimum for H1 lumi, might be dangerous, because of possible significant acceptance limitation. Thus "higher lumi" may be simply an artefact of large (and may be wrong, or at least not precise enough) PD-acceptance correction. This may (and should) be checked with real data (LUMM bank, acceptance corr. factor value). Moreover, I think, this correction is now not correct in fact. Because already in 1995, for a beta function 1.5m we had ~97.2% average acceptance. Now, with even smaller beta function, this value also should be smaller, while online is used larger estimate for A(PD) as far as I understand. This may be responsible for the part of the big difference between H1 and ZEUS lumi (additionally to the real 8-9% difference). Note also, that A_PD correction is effective for both methods of lumi measurement (in case of coincidence, the correction includes also ET acceptance variation, but PD of course as well). By the way, I want to remind again my opinion: since we do not know in advance the real offset of the trajectory, the tilt correction to ET is in general wrong, and should not be applied at all. Thus, both methods should only use "safe" A_PD correction. The rest is done offline anyway. 28/08/96 ============= Michael Winde === Lumi RUN# 1075 Start - End of Run 1075: 28/8/96 20:34:38 - 21:33:47 Collision time for H1Run - physics: 21:33:37 - 21:33:47 Currents at the begining (mA): Ie= 37.6, Ip= 61.81 max lumi value, (last record): 1.866, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.16, (0.691) mkb-1 s-1 mA-2 collided bunches = 0 e+(-) bunches = 0, p-bunches = 186 e-pilot b. = 0, p-pilot b. = 186 HERA total lumi: 0.43 nb-1 HERA - physics: 0 nb-1 H1Run - physics: 0 nb-1 H1data - physics: 0 nb-1 H1 operation eff.: 0 % , DT corr.: 0 % , Tot eff.: 0 % H1 Runs: 157001 - 157001 29/08/96 ============= Michael Winde === Lumi RUN# 1076 Start - End of Run 1076: 28/8/96 22:32:37 - 8:08:45 Collision time for H1Run - physics: 0:13:06 - 8:08:45 Currents at the begining (mA): Ie= 36.44, Ip= 61.50 max lumi value, (last record): 3.627, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 1.14, (1.14) mkb-1 s-1 mA-2 collided bunches = 179 e+(-) bunches = 189, p-bunches = 186 e-pilot b. = 10, p-pilot b. = 7 HERA total lumi: 84.69 nb-1 HERA - physics: 80.39 nb-1 H1Run - physics: 61.85 nb-1 H1data - physics: 55.01 nb-1 H1 operation eff.: 76 % , DT corr.: 88 % , Tot eff.: 68 % H1 Runs: 157006 - 157027 P.S.

Today I found that positron beam energy is changing (a little) from one Lumi RUN to another Lumi RUN (it was seen changings from 27.564 up to 27.572 GeV). Changings were fixed even during Lumi RUNs (see Lumi RUNs 1076 and 1080. For any case I am making changings at OffLine Energy for calibration value (27.568->27.569->27.570->27.571) due to at fine tuning procedure I can find Global Energy Shifts with needed precision (in framework of ordinary floating point precision - 7 digits) and I see that even 0.001GeV changings at e+beam energy can produce another value of Global Energy Shifts. You can see from all "Calibr" messages of this year that after fine tuning it were reproduced values 27.54GeV or 27.568GeV or 27.569 GeV of e+beam energy at ETrec+PDrec spectra for ETPDnVC, ETPDVC and ET44VC samples in framework of latest h1rec release.

It were selected 32215 events with ET44VC from G+M H1Runs which are kept at 510-557 LUMIMONs and which are accessible through index-file: H1KFOM.CALIBR.M164557.IND.C00 which is kept at /acs/data/96/lumi-pool with: SELECT BOSINPUT RECNAME = RUNEVENT NUMRA=157330:157622 & CLASS = 3 CLASS = 6 From this data set it were selected 8674 events with VC=1 and with using of all later mentioned cuts. These events were used for calibration. Channel et01 was used again as non-Dead channel. Next cuts were used: c1) Energy deposited at et1,et3 and et5 must be more then 0.60 GeV; c2) 19.1GeV 37500 (near 5Hz) - factor 4 S92 - 150000 -> 18750 (near 2Hz) - factor 8 S93 -1000000 ->250000 (near 1.5Hz) - factor 4 S94 - 50000 -> 3125 (near 5Hz) - factor 16 S95 - 200000 -> 50000 (near 1.5Hz) - factor 4 Total S91-S95 Trigger Rate is near 15 Hz from 36 Hz total logging rate. Second scan was started near 13:50 and finished near 14:18. After end of second scan: ZEUS Specific Lumi was near 0.42 mkb-1sec-1mA-2 (may be due to H1IP Scan some effects). H1 Specific Lumi was near 0.38 mkb-1sec-1mA-2. It means than H1 shows Sp.Lumi on 10.5% less than ZEUS or than ZEUS shows Sp.Lumi on 12% more than H1. Third and fourth scans were made at ZEUS IP (from 14:36 up to 14:51 and from 14:56 up to 15:10). During scan at ZEUS area the Sp.Lumi at H1 became less (0.38->0.33).ZEUS started scans from 0.45 and finished with 0.45 as H1 from 0.38 to 0.38 mkb-1sec-1mA-1. At 15:31 HERA changed beam tilt seen at changing from near -1.5 cm to -0.5 cm and Sp.Lumi at H1IP became more(near 0.36 mkb-1sec-1mA-1) At 15:34 (as seems) beam scan exercises were finished at "Luminosity Run" was proclaimed again. P.S. Off line check of Lumi values from LRTL and LUMM banks show that from 120 up to 290 min from start of Lumi RUN# 1089 (during Luminosity Scan exersises at H1 Interaction Point) the difference between OnLine PhotonArm Rate Method Lumi Values and OnLine ET&PD Rate Method Lumi Values was near 3% (Ph.Arm Lumi was more on 3% as almost ordinary at last time) (a.f.). 05.09.1996 ================= H1KFOM === ET44 at Working Position ... Today after Ie+ became less than 15mA (at 19:07) HERA with care put the H1ET44 into New Working position (on 13.3mm closely to e+beam as earlier if it was correctly understood). Previous Working Position is -14.0mm at HERA counts and New Working Position is -0.7mm at HERA counts. At 19:17 position -0.7mm was achieved. There were not fixed any changing at p-beam & e+beam background rates, radiation monitor rates. Rate of ET44-trigger element was changed from 37 kHz to 94 kHz. Xet44-coordinate distributions was changed in accordance with new working position (at L4 histos and H1Lumi OnLine Monitoring Tools). It was recorded H1Lumi Dedicated Run 157922 with S90 and Random Triggers only (near 40K of S90 events with New Working Position).

Today after 09:00 H1 operation meeting where it was discussed the question of writting of ET44-position to any DataBase with posibility of getting this data for analisis, reconstruction, calibration etc. Tim Wilksen who agreed to help make some steps at this direction had made first step - data about ET44 position are now available at xctrspy procedure together with RomanPots, Collimators etc. H1ShiftCrew from today can see ET44 position at X-terminal. Second step which was promised to be done by Tim - writting of this values into SlowControl Oracle DataBase. He promised to let V.Andreev know when it will be made. Getting data from Oracle DB for insertion into analisis,reconstruction calibration etc. can be done with the same way as it is used for example for RomanPots Position data etc. Let's hope that somebody who can make this type of operations with Oracle DB can help to H1Lumi at this question. 06.09.1996 ===== Calibr ==== H1KFOM === Sample 5A Relation Coeff.Set It were selected from 559nd-572th LUMIMON data sets events which are used for 11th at this year 'standard' calibration.

However, ZEUS on-line lumi was almost 15% lower than HERA expectations. On the other occasions also rather poor correlation between the measured p emittance and Lspec was observed. ...." As seems at this message it were made some errors. It is logical that (Lspec (HERA) and Lspec (H1/ZEUS) must be vice versa): o final results of the lumi scans were presented: H1 ZEUS beam width hor. 217.5 219.5 um ver. 57.3 53.5 um Lspec (HERA) 5.29 5.50 x 10^29cm-2mA-2 Lspec (H1/ZEUS) 4.0 4.8 May be first line is vice versa too? (217.5<->219.5) Who knows? More detail: o H1Lumi had measured on [(4.8-4.0)/4.8]*100=16.7% less than ZEUS Lumi. or ZEUSLumi had measured on [(4.8-4.0)/4.0]*100=20.0% more than H1Lumi. o H1IP Beam width hor. on [(219.5-217.5)/219.5]*100=0.9% less than ZEUS or ZEUSIP Beam width hor. on [(219.5-217.5)/217.5]*100=0.9% more than H1 o H1IP Beam width ver. on [(57.3-53.5)/53.5]*100=7.1% more than ZEUS or ZEUSIP Beam width ver. on [(57.3-53.5)/57.3]*100=6.6% less than H1 H1Lumi can measure on [from (6.6-0.9)=5.7% up to (7.1-0.9)=6.2%] Luminosity value less than ZEUS. If You take into account difference ET&PD method and PD-method on near 3% (during scan) and possible error at ACCC-defining (due to another beam optics for e+beam at this year (near 2% with estimation of S.Levonian) than it is possible to suppose that H1 can measure Luminosity value less than ZEUS on (5.7-6.2)+3+2=10.7-11.2%. We had difference 16.7%. It means that 5.5-6% of difference are not understandable. At case if somebody mistaked at first line (217.5<->219.5) than only 3.7-4% difference is not understood. I did not know distinctly the results of Nelly's OffLine Lumi estima- tion (something as 3% was used at discussion with Phill Biddulph about Lumi scan results - the same as OnLine Photon Arm measured). From another hand - if You see into LLO 05.09.96 message about Lumi scan - specific Lumi value (which were read from ZEUS Lumi Monitor and H1Lumi Monitor) were not 4.8 and 4.0 but 4.5 and 3.8 - so difference was really 15.5%. It means that 1.2% of difference can be explained with enough 'rough' fixing of both Specific Lumis. It means that we had from 2.5 up to 4.8% of not understood difference. 12/09/96 ================= G.

Are any proposals to make it more correct? Why it is needed to make huge quantity of LESC and LFRC versions? May be at H1DataBase some option exists for this case? Who knows? from Run 157998 - LFRC and LESC with ET44 Old Working Position (A) from Run 158021 - LFRC and LESC with ET44 New Working Position (B) from Run 158065 - LFRC and LESC with ET44 Old Working Position (A) from Run 158084 - LFRC and LESC with ET44 New Working Position (B) A and B sets will be deffered with 6 Relation Coefficients for ET44 (last 6 values at LFRC-bank) and with 1 Global Energy Shift for ET44 (last 1 value at LESC bank). 5) for 5C-sample (as seems) no any statistics with Old Working Position of ET44. May be after 5B-sample we shall forget forever about Old Working Position due to impossibility of ET44 calibration for this position. 14/09/96 =================== D.

ET44 was moved into New Working Position (-0.7mm at HERA counts) between 10:03 and 10:06 and was at this position up to end of Lumi RUN #1104 (a.f.) P.S. During This Lumi RUN it were fixed two resets at both H1 Gated and H1 Data taken Integrated Lumi: 1)near 11:57 (first one was decremented on 0.4nb-1 and second one - on 0.3 nb-1); 2)near 22:03 (on 3nb-1 and 2.5nb-1) (a.f.) 15.09.1996 ================= H1KFOM === Extra Quick ET44 Moving (?) . Tonight during start of Lumi RUN 1105 it were fixed at different rates history that ET44 was at New Working Position from start of Lumi Measurements (from 02:52 when step 1 was executed for h1Lumi). One of possible scenario: 1) 02:48-02:50 last phase of e+ring Ramping; 2) 02:50-02:51 moving of ET44 into New Working Position; 3) 02:52 - H1Lumi Movable Platforms are at Working Position (Step1 was executed at H1Lumi); 4) 02:58 - good Lumi values were measured at H1IP. May be this type of sceanrio will be routine as it was planned earlier - immediately after e+ramping ET44-moving is made? Second scenario is (as seems) impossible - may be ET44 was at New Working position during injection and ramping (due to enough difficult to differ at 02:50 growing of ET44-rates from ramping and from moving into New Working Position). PS(S.L.) Unlikely. The positron beam shold then be lost during the rapming, because its size and trajectory need more space at a position of ET44, that is available when the tagger is in working position... 15/09/96 ================ A.

ET44 was at New Working Position (-0.7mm at HERA counts) during all Lumi RUN (see message earlier) (a.f). P.S. There were any resets at any Integrated Lumi for Run Summary at this Lumi RUN. Integrated Lumi for some H1Runs were corrupted again (this corruption exist almost at all Lumi Runs - from 1 to 4 H1Runs). Special remark at H1EP had appeared - * Int.Lumi in reality >AAnb-1 * Online Int.Lumi corrupt! where AA is biggest Int.Lumi at all LRTL-banks of this H1Run. Up to now version about 'noise' TerminateRun Interrupts exists as the reason of mentioned corruptions (a.f.). P.S. after end of this lumi run HERA crew made some exersises with beams up to 14:20 and after this both beam were dumped (a.f.). P.S. After end of this Lumi RUN (during Run 159140) Egor changed threshold into low direction at "PD_high" trigger element(TE 112 (threshold for PD_high is less then threshold for PD_low and reallly this is PD_very_low). Rate for PD_high now more then rate for PD_low on 30%. This trigger element will bee used at s62 subtriiger and will replace PD_low which was used before. It was made with request of Siegmar Schleif (Radiative Correction Group) (a.f.). 15/09/96 =================== H1KFOM === "Toroid ON" again Today afternoon H1Lumi-application after 3 days of delivering of wrong information about currrent at H1 Toroid (it was always "Toroid Off") into HERA Control Room started the delivering of correct information (Jan Olsson, Ralf Gerhards, Samvel Kazarian and John Coughlan were involved into recovering of wrong data at dice1 where H1Lumi-application gets this inforamtion).Thanks to all. 15.09.1996 ====== L4Histos = H1KFOM === L4Reference Histos for H1Lumi Today morning I was called by H1ShiftLider with problem of L4Reference histos for H1Lumi (K.H.Meier). I checked with KOOL the L4-histos from Run 159126 and found that only ET44 X-coordinate distribution and TriggerElements versus BunchX-ings histos are significantly changed.

It is first Lumi RUN with new threshold for PD_high which became as PD_very_low now - see P.S. for previous LumiRUN(a.f.). 16.09.1996 ================= F11LEV === PD acceptance in 1996....... It was found, that the acceptance of the Photon Detector is signifi- cantly smaller that in 1994 and 1995. This is perhaps because of the new positron optics used (smaller horizontal beta-function). This has to be verified with HERA experts, until then the average correc- tion to the online Single Photon Lumi can be roughly estimated as +7.5% For the lumi scan results (5-Sept) the real difference between H1 and ZEUS lumi is 4.7+-1.4%, after correcting online coincidence measurement by 13.2% up. We have to find out the real acceptance of PD for the whole 1996, to correct online lumi on this large effect. For that LUMIMON data has to be analysed in a same way as I did for lumi scan sample. Also a new procedure must be implemented online to automatically account for A(PD) changes as a function of tilts and divergences (not only tilts). All the details can be found in a series of mails, which I sent to Lumi group over the last two days. 16/09/96 =========== Stephan Wiesand === Lumi RUN# 1107 Start - End of Run 1107: 16/9/96 11:52:14 - 23:22:52 Collision time for H1Run - physics: 12:27:34 - 23:22:52 Currents at the begining (mA): Ie= 32.65, Ip= 61.65 max lumi value, (last record): 1.185, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.321, (0.691) mkb-1 s-1 mA-2 collided bunches = 165 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 24, p-pilot b. = 15 HERA total lumi: 100.1 nb-1 HERA - physics: 96.05 nb-1 H1Run - physics: 89.68 nb-1 H1data - physics: 78.09 nb-1 H1 operation eff.: 93 % , DT corr.: 86 % , Tot eff.: 81 % H1 Runs: 159257 - 159299 P.S.

As You can read earlier at last "Calibr" reports the CCe14 at OnLineCalibrationProcedure is marked as 'noisy'. As seems it is due to enough wide (as seems) pedestal distrubution at FADC channel connected with e14. Similar effect is seen at CCe10 and CCe40 at PhotoProduction branch (at OffLine Calibration Procedure) Today morning the value of CCe14 was found as 49.26 (it means that really CCe14 became as near 160MeV/FADCcount at Luminosity branch in compare with onother CC with values near 6-7 MeV/FADCcount. Influence of noise at e14 on OnLineCalibration Procedure became enough significant. It is possible to see at OnLine Energy Histos that became significantly less that . Value of sigma at OnLine ETrec+PDrec histo became near 1.33-1.36 GeV. May be it was the reason of last degradation at Sigma at OffLine ETrec+PDrec histos too. So - as test - CCe14 was installed 'by hand' on new value (similar to neighbour channels (49.26->1.7). CCe15 which as seems is currupted too (but into another side during 'straggle' with huge e14-response) was incremented (0.48->1.7). As seems similar procedure must be involved for OffLine Calibration CC start values too for e10 and e40 channels. P.S. Experience of Lumi RUN 1109 with mentioned earlier intervention: As it seen from OnLine Energy distributions ETdep and ETrec the intervention is estimated as reasonable. became even more as as it was ordinary before similar behaviour of CCet14 which was fixed at 1995DataTaking.Sigma at ETrec+PDrec spectrum for ETPDnVC sample became less (1.27-1.28 GeV). Let's hope that at OffLine Calibration Sigma will become less as at last calibration samples after similar intervention into start CCe10 and CCe40 values (a.f.) 18.09.1996 ================= H01GOG === Some news from HERA Yesterday in HERA meeting B.Holzer informed that results of last Lumi Scan were presented wrongly. The correct numbers are: H1 ZEUS beam width hor. 232.3 218.0 um ver. 57.3 53.4 um Lspec (HERA) 4.90 5.60 x 10^29cm-2mA-2 Lspec (H1/ZEUS) 3.8 4.7 It means that a difference between H1 and ZEUS luminosity values is about 13.3% ( d = 2*(L(Z)-L(H1))/(L(Z)+L(H1)) ). HERA experts are going to investigate the optics and beta-functions of e-machine, and will let us know the results. They are looking forward to our correct online luminosity value as well. This year, from the first official Lumi Run onwards, e+ beam optics was changed (compare to 1995). The whole listing of beam parameters you can find in my directory on dice2: ~nellyg/short_list ~nellyg/long_list Here, I'll give some numbers (for 1996),which I just verified: beta_x = 1.02 m +- 0.01 beta_y = 0.98 m +- 0.01 emitance_x = 4*10**(-8) m*rad (precision < 1%) emitance_y = ~10% of emitance_x (precision > 20%) 18.09.1996 ================= F11LEV === PD acc. and optics'96....... I made some comparisons between "theoretically" expected values of positron beam divergence, and our measurements from available data samples. The angular divergence is defined as sigma_x|y = sqrt(emittance_x|y / beta*_x|y) and is a crucial parameter, defining -- together with beam tilt -- the geometrical acceptance of the Photon Detector to the BH photons. Using the values from HERA machine (see also a message above), sigma_x = sqrt(4.137*10^-8/1.02) = 0.201 +- 0.002 [mrad] sigma_y = sqrt(0.414*10^-8/0.98) = 0.065 +- 0.013 [mrad] Using coordinate distributions at PD (selecting "clean photons": 2.5 < E_phot < 30 GeV and E_VC/E_phot < 0.02), Run range sigma_x [mrad] sigma_y [mrad] A(PD) [%] 147117-147813 0.185 +- 0.005 0.047 +- 0.002 93.1 +- 0.7 147918-151230 0.193 +- 0.003 0.050 +- 0.002 95.0 +- 0.7 151600-153364 0.208 +- 0.004 0.056 +- 0.002 93.2 +- 1.0 157889-157893 0.212 +- 0.007 0.056 +- 0.002 85.0 +- 1.0 157894-157937 0.201 +- 0.005 0.052 +- 0.002 92.2 +- 0.8 Last two samples corresponds to the two halfs of lumi fill 1089, when the lumi scan was made. Conclusions: ------------ 1) Measurements are in a reasonable agreement with expectations. Note also, that the coordinate resolution contributes to the measured sigmas. It has negligible effect on sigma_x, but visible for sigma_y (increases sigma_y value by 8-10%). In principle, it is rather well simulated by H1LUMI MC. 2) The precision of sigma_y determination from HERA is poor, therefore we have to rely solely on our own measurements. 3) It is still not clear to me, whether the variations of sigma_x reflect a real effect (varying optics), or related to systematics in our measurements. The consultations with machine experts may be useful. They perhaps would be interested to see this comparison. 4) Note large variations in A(PD), as well as big difference compared to = 98.7% and = 97.2% 5) I am waiting for the remaining LOOK files, to complete this analysis and to estimate A(PD) corrections to the past Lumi measurements.

It were seen that not always HERA crew supported the recommended values (may be they wanted to investigate - is it really best positions?) (a.f.). PPS(S.L.) How can they investigate, based on the wrong A(PD) corrections? Of course, they may come to different conclusions! Before they strat to investigate, you must provide them with correct result! Second: for us now more important to keep relatively large and therefore better controllable acceptance of PD. This will be one of the dominating systematics. The acceptance of ET (and therefore the coinc. Rate) may have indeed different optimum (depending on trajectory offset), but who cares? This is now of secondary importance. 18.09.1996 ===== OnLine ==== H1KFOM === LUPO and LR1P BOS banks ....

P.S.(S.L.) Why not Y1 = Y0/10.3 ? According to your own drawings (Usik, WWW) the PD position is 103m, not 102m. By the way, what means "direct measurement of Photon Beam Position"? Fast h/w estimate from Egor, or mean values from online s/w? If latter, than what is used? X_rec, y_rec from LREC? Else? Which selection? Anyway, whatever it is, it is better than before. P.S.(a.f.) 10.2 was used ever before. mean values from online s/w (Xrec,Yrec from LREC and for ETPDnVC events only). Egor said that it is early to use his fast h/w estimation. ==> OK, then only 0.9% additional error remains (if A.F. for some reason insists on wrong distance to the PD...). I don't care, since offline I will use correct value anyway. 20/09/96 =========== Stephan Wiesand === Lumi RUN# 1112 Start - End of Run 1112: 20/9/96 9:06:31 - 20:39:18 Collision time for H1Run - physics: 10:05:56 - 20:39:18 Currents at the begining (mA): Ie= 32.99, Ip= 65.55 max lumi value, (last record): 0.354, (6.012) mkb-1 s-1 max sp.Lumi value, (last record): 0.099, (0.691) mkb-1 s-1 mA-2 collided bunches = 174 e+(-) bunches = 189, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 6 HERA total lumi: 116.94 nb-1 HERA - physics: 106.25 nb-1 H1Run - physics: 98.73 nb-1 H1data - physics: 88.04 nb-1 H1 operation eff.: 92 % , DT corr.: 89 % , Tot eff.: 82 % H1 Runs: 159808 - 159827 P.S.

Reference Histos changing was connected with involving of ET44 moving into New Working Position and with involving new threshold for PD_high which became as PD_very_low now which is included into s62 subtrigger for Radiation Correction Group reguest. Changing was made by Arndt Boris Fahr after exchange of mails started at 19.09.96 17:33. It was tested one from current H1Runs (159922). All histos are at good agreement with Reference Histos (agreement not less than 91%). 91% is fixed at histo due to HERA at Run 159922 tuned on value more than 0.0cm.

Today during Lumi RUN #1115 ET44 was moved into 'new' working position -1.0mm (not -0.7mm as it was before from Lumi RUN 1089 up to 1114). 23.09.1996 ===== Calibr ==== H1KFOM === ET44 Rel.Coeff.Set 5A -157922 Today it was defined Relation Coefficients Set for ET44-channels at events from H1Lumi Dedicated Run 157922. This Run was recorded with S90 and Random Subtriggers only with New ET44 Working Position at 05/09/96 during Lumi RUN 1089 which is connected with 5A-data sample. So Relation Coefficient Sets for ET and PD with CCvcs and Global Energy Shifts were used from 5A-sample. Firstly it was used the 'standard' ET44 reconstruction package for calibration making (not simpliest one which was used for Old Working Position). Three iterations were involved into OffLine ET44 Calibration Procedure.It were selected 20227 events with ET44VC from H1Run 157922 which are kept at 568-571 LUMIMONs and which are accessible through index-file: H1KFOM.ET44VC_NWP.M568616.C00 which is kept at /acs/data/96/lumi-pool with: SELECT BOSINPUT RECNAME = RUNEVENT NUMRA=157922 & CLASS = 3 CLASS = 6 From this data set it were selected 6113 events with VC=1 and with using of 4 later mentioned cuts. These events were used for calibration. Channel et01 was used again as non-Dead channel. Next cuts were used: c1) Energy deposited at et1,et3 and et5 must be more then 0.60 GeV; c2) 19.1GeV-1.099 - first cut another as at OnLine Calibration of ET44 channels and 4th cut is absent at OnLine Calibration. It was investigated that influence on selection of c1&c2&c3 cuts and c4 cut is almost similar with influence on ET44Rec+PDrec spectrum shape and (as seems) more reasonable and understandable - so for fine tuning at ET44 OffLine Calibration procedure it was used only c4-cut. It was made (firstly) 3 iteration procedures during Relation Coefficient Set defining procedure (as it is made for ET/PD RC). As start values CCet44 were got CCet44 produced at calibration for 5A data sample from H1Runs 157870-157907 - see message 07.09.96 at LL14. et0 = 9.148 et1=7.358 et2=12.651 et3=7.730 et4=4.973 et5=6.910 Next Relation Coefficients Set was produced: et0 = 0.520 et1=-.--- et2=1.117 et3=1.139 et4=0.548 et5=0.902 Sigmas at Relation Coefficients Histos: et0 = 0.002 et1=-.--- et2=0.021 et3=0.014 et4=0.015 et5=0.000 Statistics per channels used for calibration (with 3 iterations): et0 = 53 et1= 0 et2=18340 et3=16916 et4= 425 et5= 3 Final Values of CCet44 are the next (MeV/FADCcount): et0 = 9.255 et1=7.358 et2=12.573 et3=8.434 et4=4.536 et5=6.905 It was made attempt to define Global Energy Shift for ET44-channels. All 20227 mentioned et44vc events were processed with last release of h1rec71301 with insertion of procedures similar to OnLine et44- channels calibrations.

Today it were tested contents of new LUPO and updated LR1P-banks which are appeared at H1DataFlow some days ago due to ET44-position writting. On the first view all is OK. Updated LR1P-banks were found only at data starting from Lumi RUN #1111 (H1Run 159715 etc.). ET44-positions were got from LUPO-banks (TCL 136-140) and LR1P-banks were got from ETPDNVC-events of last (5E)-sample. Really values -14.0mm, -0.7mm, -1.00mm and some intermediate values (during moving) presented at mentioned data. At LR1P-banks from near 100000 values it was found 3 with 'non- correct values (zero) at 5E-sample data. Luminosity value which is written into LUPO-bank was tested too - only one remark - this value is not 'zeroed' after end of Lumi RUN. It will be corrected. As seems ET44-position which was earlier labeled as ET44_ZEU is ET44-position from 'Motor Number 2'- H1ET44. Absolutely the same values were got from this second value at both LUPO and LR1P-banks. But Usik wrote at his mail that 2nd set of values is connected with ZEUS ET44 position. Let's wait of Usik's explanations. So - banks can be described as next: ! BANKname BANKtype ! Comments !

It were checked histos a) from H1Run 160650 (Phase 4) and next results were produced(7.46nb-1) Xet,Xpd,ETrec,ETrec+PDrec - 99-100% of agreement with Ref.

As seems mentioned differencies with Ref.Histos are connected with involving of latest calibration constants (especially on ET44 connected histos) and fine tuning of ET44 and ET8 Trigger elements making. p07(?) problem under investigation. P.S. (29.09.96). During calibration steps with 5F-sample it was put some attention on Xpd-distribution for ETPDnVC,PDnVC samples at p07-region. There are no any problems with p07. As seems mentioned spikes were connected with some subtriggers where PD-energy is absent and spikes are connected with pedestal 'noises' at PD. 26/09/96 ========== Vincent Lemaitre === Lumi RUN# 1120 (Largest Lumi) Start - End of Run 1120: 26/9/96 9:39:51 - 22:26:40 Collision time for H1Run - physics: 10:13:10 - 22:26:40 Currents at the begining (mA): Ie= 34.6, Ip= 66.37 max lumi value, (last record): 5.619, (6.375) mkb-1 s-1 max sp.Lumi value, (last record): 0.549, (0.691) mkb-1 s-1 mA-2 collided bunches = 176 e+(-) bunches = 191, p-bunches = 180 e-pilot b. = 15, p-pilot b. = 4 HERA total lumi: 148.45 nb-1 HERA - physics: 146.29 nb-1 H1Run - physics: 122.45 nb-1 H1data - physics: 103.49 nb-1 H1 operation eff.: 83 % , DT corr.: 84 % , Tot eff.: 70 % H1 Runs: 160590 - 160653 P.S.

I have two questions to the onliners: 1) There was a strange "step" observed in the ratio L1/L2 during the lumi run 1122 (in the middle of H1 run 160801, at ~ 12:15). Namely: this ratio suddenly changed from ~1.1 to ~0.9, and then stays at that level until the end of this fill, and during the next one (1123). L1=coinc.method(LRTL), L2=photon meth(LUMM). The plots can be inspected at dice: ~f11lev/lruns/TCL_146.ps The time is suspiciousely close to the time of LUMI Hard disk "recovering". To me 0.9 looks more correct... There was no change in the Acc. values at that time (in both banks A stayed at the level of ~0.94 all the time) Questions: - do you have an explanation of that? Something wrong withLUMI operation between Disk crash and recover? - is it true, that last time (days, weeks?) the difference between two online methods is as big as 10%? - if yes, than H1 "true" lumi is only 3-5% less than ZEUS, not 13-15% as written in run coord. summaries. 2) There was a proton beam loss at the end of lumi fill 1023. Positrons were kept for two more hours, by request of HERMES. However, looking in LUMI history plots, I see, that our detectors went to the parking positions, or simply lumi measurements were immediately stopped. It is pity, since it was a good opportunity to check the bgr. calculation precision with real data. Please, make sure, that the shift crew knows what to do in such occasions. 29.09.1996 ================= H1KFOM === Re: Strange observation .... You are absolutely correct at Your conclusions that 'recovering' of HD at H1Lumi2 is connected with Your mentioned 'jump'. For correction of 'visible' cross-section of BH for PD-method of Lumi measurements it is using some Egor's preparing value - after seaching of threshold position for current Lumi Fill. I do not know distinctly where this value is prepared (may be at Long_History -application which can operate only at H1Lumi2, may be at T_Monitor_NC). So it is explaining of Your founded on the first view strange 'jump' from 0.9 to 1.1 at time when (may be) Egor submitted his Long_History (or T_Monitor_NC) Application at recovered H1Lumi2. I checked (sometimes) difference between L1 and L2 - last time - Lumi RUN 1114 (difference was changed with time but always L1/l2 was near 0.9-0.95. It is ordinary situation that L2 is more than L1 (sometimes it is 3-5%, sometimes 7-9% sometimes 10% and more - it depends from Lumi Fill). At last Lumi RUNs this difference is more or less stable during Lumi Fill. At First Lumi RUNs which were checked and reported at LLO - ordinary at Start of Lumi Fill - difference was more and became less to end of Fill. As seems Ph.Method shows more 'correct' Lumi - so You are right at Your last conclusions that difference H1/ZEUS (if we are using the Ph.Arm Lumi) became not so drastical as RunCoordinator mentioned - after correction of ACCC - near 5-7% which can be explained with beam sizes at H1/ZEUS IPs. It would be good to write ZEUS Lumi into some H1 bank as it is made with ET44 Position - as seems - somewhere ZEUS Lumi value exists at similar text file (for more detail inspections of ZEUS/H1 Lumi Differencies). May by Sasha Usik can get this data from his friends anywhere and put into DPM. It would be very good. If connecting to p-lost at last Lumi RUN: I do not know that anybody from us asked H1 Crew or H1 Run Coordinator to make Your proposed procedure. Egor said (as seems) enough reasonable remark on Your proposal. Why to wait beam lost or something else - at the start of any Lumi Fill it is good known that beams are separated and we are measuring Lumi near Our 'Lumi zero'. You can use this data. Nevetheless as seems it is possible to ask of H1Run Coordinator to make Your proposed steps at rare cases of p-beam lost and to use these 'happy' opportunity to be sure at Our 'Lumi zero'. 29.09.1996 ===== Calibr ==== H1KFOM === New RC Sets in H1DataBase(5F) As final action of all 28.09-29.09.96 calibration steps it was made update of LFRC and LESC banks at H1DataBase with S.Levonian's tool for 5F Sample: Bank-ID Rtyp Dtyp Version 1.Run L.Run Words Date Author Bank LFRC (_501) ---- 5E-sample ------------------------------------------------ NWP 113 e-p data 609242041 159583 159916 83 960924 fomenk ---- 5F-sample ------------------------------------------------ NWP 114 e-p data 609291621 159917 0 83 960929 fomenk Bank-ID Rtyp Dtyp Version 1.Run L.Run Words Date Author Bank LESC (_582) ---- 5E-sample ------------------------------------------------ NWP 135 e-p data 609242041 159583 159916 4 960924 fomenk ---- 5F-sample ------------------------------------------------ NWP 136 e-p data 609291621 159917 0 4 960929 fomenk 29.09.1996 ===== Calibr ==== H1KFOM === Sample 5G Relation Coeff.Set It were selected from 826th-861st LUMIMON data sets events which are used for 17th at this year 'standard' calibration.

Today it was made attempt to make first at this year calibration of eTAG8-channels (SPACAL similar two calorimeter channels). Last Egor's tuning of FADC shifts, t0-timing and another tuning actions put good results which are seen at ET8-triggered events data. Starting from H1Run 160348 (Lumi RUN 1117) ET8-data became more or less reasonable and have some correlations with H1Lumi Photon Arm detectors and another H1 Trigger Elements 'Families' (zvtx,digMuon, SPCLe,SPCLh,MWPC,DCRPh,FWdRay,BackBR,TopoBR,FPS,Bplug,Veto,ToF(1)veto). S99-subtriggers produces as Raw Subtriggers a)S91,S93,S92 - as Bremstrahlung candidates(coincidence with H1Lumi PhotonArm); b)SPACAL- connected subtriggers s06,s11,s101,s109,s110,s111; c) Muon-connected subtriggers: s30,s31; d) zvtx-connected subtrigger: s104; e) Tracker connected subtriggers: s49,s100,s113; f) FWdRay-connected subtrigger s109 g) a lot of etag_all connected subtriggers: s80,s81,s85,s86,s105. Intensities of mentioned subtriggers concidencies are different and for most from their its are only Random Coincidencies with S99. But coincidencies with zvtx,SPACALe,SPACALh,Muons,DCRPh,FwRay trigger elements show that there are a lot of future interesting investigations with eTAG8-triggered data. For calibration case it was needed and it was found coincidence of etag8 triggered events with H1Lumi PhotonArm (s91,s92,s93). For calibration of eTAG8-data it were selected all eTAG8 triggered events from LUMIMON-data sets connected with 5G-sample (H1Runs 160680- -160858) from G- and M- H1Runs only. It were selected 35641 events with CLASS=8. eTAG8 Calo Data are written at LR2F-bank as RawData (as FADC pulses at 2.2 neigbours bunch-X-ings). It was found that pulses maxima are disposed at 3rd bins of 22-bins 'FADC window'. It was made procedure of 'digitization' with FADC-counts making for each from 2 Calo channels. As pedestal value first bins were got (may be not best decision and it is needed to make some additional investigation with pedestal substraction mode). Only 2nd-7th bins were got for producing of FADC counts from bin values more then pedestal for each channel. After mentioned 'digi' procedure there are 2 values at FADC-counts related to Energy Deposition at each from two eTAG8 Calo channels. The main task of eTAG8 Calibration Procedure - to find calibration coefficients for both channels at MeV/FADCcounts units. For eTAG8-case H1LumiOnLineSW does not produce any OnLine Calibration Coefficients. So eTAG8 Calibration means namely Calibration Coefficient finding for both channels (not Relation Coefficients as it is making for ET,ET44 and PD-detectors Calibration Procedure). eTAG8-calibration is similar to VC-calibration. Moreover - Egor predicts that CCet8 must be more stable as CCet,CCpd,CCet44 and CCvc (another photomultipli ers, another rates (near 3-8KHz only)). There is no any reconstruction package for eTAG8 and it was decided to try the calibration procedure similar to CCvcs defining where we have only VCdep-response and Calibration Coefficient is accounting (or compensating) some shower leakages etc. Taking into account all earlier mentioned problems and procedures it was made first attempt to estimate and later - to define Calibration Coefficients for eTAG8 channels. As start values for CCet8 iteration procedure it were got ones from 'rough' estimation from et8dep-FADC counts spectra shape with supposition that both CCet8 have similar (equal) values. It was found that with values 2.671 MeV/FADCcount ET8dep spectrum is looking for as reasonable for events with 'reasonable' PDrec-value (more then 22 GeV - from V.Andreev estimation). So - from all 35641 eTAG8-triggered events it were selected 3209 ev. with the next cuts: c1) PDrec exists; c2) 0.8GeV6mA). P.S. Background conditions were enough hard during this fill: e+beam background was more than 2-3kHz and p-beam background -100-200kHz 06.10.1996 ===== Calibr ==== H1KFOM === CC Behaivours with Time_96...

From this data set it were selected 1760 events with VC=1 and with using of 4 later mentioned cuts. These events were used for calibration. Channel et01 was used again as non-Dead channel. Next cuts were used: c1) Energy deposited at et1,et3 and et5 must be more then 0.60 GeV; c2) 19.1GeV-1.099 - first cut another as at OnLine Calibration of ET44 channels and 4th cut is absent at OnLine Calibration.

These events were used for calibration. Channel et01 was used 2ndly as Non-Dead channel really (6C - firstly). Next cuts were used: c1) Energy deposited at et1,et3 and et5 must be more then 0.60 GeV; c2) 19.1GeV-1.099 - first cut another as at OnLine Calibration of ET44 channels and 4th cut is absent at OnLine Calibration. It was investigated that influence on selection of c1&c2&c3 cuts and c4 cut is almost similar with influence on ET44Rec+PDrec spectrum shape and (as seems) more reasonable and understandable - so for fine tuning at ET44 OffLine Calibration procedure it was used only c4-cut. It was made 3 iteration steps during Relation Coefficient Set defining procedure (as it is made for ET/PD RC).

These events were used for calibration. Channel et01 was used 3rdly as Non-Dead channel really (6C - firstly). Next cuts were used: c1) Energy deposited at et1,et3 and et5 must be more then 0.60 GeV; c2) 19.1GeV-1.099 - first cut another as at OnLine Calibration of ET44 channels and 4th cut is absent at OnLine Calibration. It was investigated that influence on selection of c1&c2&c3 cuts and c4 cut is almost similar with influence on ET44Rec+PDrec spectrum shape and (as seems) more reasonable and understandable - so for fine tuning at ET44 OffLine Calibration procedure it was used only c4-cut. It was made 3 iteration steps during Relation Coefficient Set defining procedure (as it is made for ET/PD RC).

These events were used for calibration. Channel et01 was used 8thly as Non-Dead channel really (6C - firstly). Next cuts were used: c1) Energy deposited at et1,et3 and et5 must be more then 0.60 GeV; c2) 19.1GeV-1.099 - first cut another as at OnLine Calibration of ET44 channels and 4th cut is absent at OnLine Calibration. It was investigated that influence on selection of c1&c2&c3 cuts and c4 cut is almost similar with influence on ET44Rec+PDrec spectrum shape and (as seems) more reasonable and understandable - so for fine tuning at ET44 OffLine Calibration procedure it was used only c4-cut. It was made 3 iteration steps during Relation Coefficient Set defining procedure (as it is made for ET/PD RC). As start values CCet44 were got CCet44 produced at calibration for 7A (NWP) data sample (Runs 167407-167925) - see message from 15.11.96 at LL14: et0 = 9.504 et1=12.178 et2=21.325 et3=6.878 et4=4.655 et5=7.889 Next Relation Coefficients Set was produced: et0 = 0.642 et1=0.805 et2=1.036 et3=1.210 et4=0.528 et5=0.998 Sigmas at Relation Coefficients Histos: et0 = 0.010 et1=0.032 et2=0.030 et3=0.059 et4=0.010 et5=0.005 Statistics per channels used for calibration (with 3 iterations): et0 = 82 et1=13684 et2=42002 et3=31966 et4= 413 et5= 36 Final Values of CCet44 are the next (MeV/FADCcount): et0 = 9.664 et1=12.996 et2=20.672 et3=6.683 et4=4.877 et5=8.025 It was made attempt to define Global Energy Shift for ET44-channels.
