I guess it is appropriate time to close previous part of the LUMI Log- book and to open a new one. You can still inspect last part by the new command LL4 = LIST 'F11LEV.H1.LUMI.LOGBOOK.JUN92.AUG92' similar to already existing commands LL1-LL3 for the first three parts. Store LL4 in your CLIST library for convenience (see lds 'F11LEV.CLIST' if not clear how to do this). I will be absent till 2-nd of September for the vacations. 20.08.1992 ===================== H01USA === e-beam .................... All night HERA played with e-beam, 12 GeV, up to ~6 mA, 23 bunches. Our detectors were in parking position. The rate of water counter was up to 170 kHz, in averaging - 100 kHz ! Expected rate for 26 Gev - 25 kHz, but for 12 Gev must be more less. 21.08.1992 ===================== H1KSOL === HERA schedule..............

Apparently there will be break on 1.10 due to HERA celebration and Open House on 3.10. After 1.10 the schedule is not clear yet. 21.08.1992 ===================== H01USA === 26 GeV e-beam ............. Yesterday it was 26 GeV beam. Some time conditions were more less good: RofET*PD = 700 Hz, RofWC=20 kHz. During this time detectors were in working position. HERA playing with beam position and observing of collimator projection on PD face allow to do final conclussion that those are not on the same axis: collimator is shifted on ~8 mm to the left (or PD to the right?). Scanning by ET detector in vertical direction (unfortunatly only for top half of ET) allowed to find one more channel with very high HV: #35 - practically no events in this module. All spectrum and plots are normal. It is a good opportunity to install new HV, but delays... Egor, may be, doverish this delicate procedure? 21.08.1992 ===================== H1KSOL === PD alignment............... During last access into HERA tunnel we (Smirnov and me) have checked (several times) the alignment of PD,using the reference line given by geodesists (F.Loefler people). We can confirm that PD is aligned on the gamma beam axes with an accuracy of +-1mm on the front face. 31.08.1992 ===================== H01USA === News ...................... This night shift we monitored lumitrigger rates for HERA. Brinkmann was in the night shift and asked to do it because they investigate this short life time problem of e-beam for big currents.They are interesting in correlation between bremstrahlung in our IP and life time and anoth er parameters, expecting that it can (may be) help to understand - this source of bad life time - is local or spreads along ring. For information - during last weeks were next changes on Macs: - HD, 80 Mbyte is installed on right Mac (so we have now 120 + 80) - 40 Mbyte disk from right Mac is saved with original data (mainly of A.Fomenko for his appearance) and of coarse is copied on new one. - New system 6.0.7 is installed on both Macs: it supports new font facility "TrueType", which provides any size of fonts and another things. - in parallel to the old MPW new version - MPW3.2 was installed on both Macs: FICs menu, Fomenko's instruction and so on were copied and tested (on left Mac during more 2 weeks). All is ok. Today instead of additional memory for Mac Bill gave us new mother board for our Mac. It is Mac IIfx !: 68030, 40 MHz, 8 Mbyte. The price 3.000,_ - the chipest way for upgrading. It is very good for last version of TVLAN application, which support at least 10 active grafics, type information and LAN in backghround. 01.09.1992 ===================== H1KSOL === HERA schedule upgrade .....

Left MAC: new mother board is installed (||fx).One floppy driver -------- (right) is replaced by new 1.4 Mbyte. MICRON card is replaced by new one. We had after upgrading two problems: - no accsess to VME, then Bill gave another (seems more faster card) MICRON card. Now - ok. - after closing any aplication by Command-Q cursor is dead (not moved) after replacing of keyboard it is alive again. It seems that old key board is slow for ||fx. Temporary the problem was decided by exchanging of keyboards of left and right Macs. Right Mac: has now 8 Mbytes of memory as left one. --------- Impressions from fx naiprijatneishie.

Last night an attempt was done to take a data with different e-beam position on the face of PD - orbit parameters in the region of H1 IP were changed. The values of e-ring optics for every RUN were transfered to IBM. The beam position monitors in the H1 IP region are NL 7 and NR 7, L - means Left and R - Right. They are disposed +- 7 m relative to IP. These data are saved in library H1KSOL.luscan.bp, and have the names like 0920912B - last letter changed for the every Run. At the beginning of each file you can find the date and time of creation, so you can easy to find correspondens of this data to Run number. Nevetheless here below can find it: Run Number File name 29207 0920912D 29210 E 29211 F 29214 G 29215 X 29216 W 29219 U 29221 T 29222 S 223 S 29224,226 Q 29227 N The data taking was done at the same time with ZEUS,so the quantity of files are more than quantity of Runs. The expirience shown that the orbits parameters are fluctuated,so it is not bad that we have got for some runs a set of parameters for the same orbit. For other information for these Runs I refer to San Palych and Egor Petrovich who were working in H1 CR. This information is in our LumiLogbook in H1CR and I think it will be appeared soon. Information for reading these files: Name of beam position X value Z value monitor horizontal vertical mm mm NL 7 -6.5 0.96 ..... Dont forget that coordinate system for HERA differs from our,e.g. X-axis direction is opposite to the one witch is used in Lumi. Further info later on.... 12.09.1992 ===================== H01USA === e beam scanning ........... The labeling of beam position (9 points: left, center, right; bottom, center, top - relatively the center of PD, view from IP): 7 8 9 4 5 6 1 2 3 Recorded runs: Position # of Run 5 (29)207,208,209 6 210 4-5 211,212 4 214 7 216 9 217,218 6 220 4-2 221 2 222.223 1 224 The on-line rates,histos and pictires are in H1CR logbook. 13.09.1992 ===================== H1KSOL === e beam scanning ........... Additional information for Runs with e-beam scanning: Some tools for measuring parameters of orbit e-beam in HERACR did not work,so we used our PD as beam position monitor and then saved file with beam optics parameters into IBM. But it was possible to measure the relative change in angle after every tuning of the orbit parameters.Here below one can find this changes for every run: Run # Xpd, Ypd Delta mrad Direction 29207 0. 0. 0. 29210 0.2 horizontal 29211 -0.4 horizontal 29214 -0.21 horizontal 29215 0.25 vertical 29216 0.45 horizontal 29220(18?) -0.26 vertical 29221 -0.1 " 29222,223 -0.15 " 29224,226 -0.2 horizontal 29227 0. 0. -0.1 horizontal -0.3 vertical 14.09.1992 ===================== F11LEV === HERA polarization ......... Last news from the machine studies (just for the general information): Up to 60 electron bunches were stored in HERA. Polarization study is finished with a preliminary result of a maximum polarization observed = 56%. 16.09.1992 ===================== H1KSOL === a new set of HV ........... Last night an attempt was made (by Egor and me) to align responses of PD and ET by tuning of HV.It was done during polarization shift Ee=26.6 Gev, Ie = 2.2 ----> 1.4 ma.The following criteria were used : 1.The high edge of the spectrum for each module should correspond the energy of incoming particle and should not depend on the lower thresholds. 2.For the permanent beam position the relation between rates of different PD- modules should not depend on thresholds. 3.PD-beam profile should not depends on threshoulds too. The files with new HV sets were written into folder DefaultHV.... and have the name FileHVPD(ET).16.09.92. Unfortunately the quality of the beam (mainly beam position) was not perfect,so we have to check this HV set under good condition. 20.09.1992 ===================== H1KSOL === CC for e-beam scan.........

Already several times it was happened that online person on LUMI shift made various changes during normal data taking without any agreement with the H1 run coordinator and CDAQ shift leader. This is unacceptable situation. Any changes, like trigger thresholds, playing with HV etc. must be at least written down into H1 logbook in the CDAQ room. This is important for the offline analysis. Otherwise nobody will know why eTAG or luminosity behaviour suddenly changed without visible reasons. Please, don't treat HERA experiment as your own, think also about other subdetectors and common H1 interests! If you need special run for the system tuning ask for that officially, rather than do things secretly. 23.09.1992 ===================== H1KSHE === Lumi Run #58 ..............

Comments: the additional peak on electron anologue sum spectra was removed by old procedure of aligning the calibration coefficients by HV changing. Thus another explanations of this peak were rejected. For HV tunning of water counter the sum analogue sum was used (min of FWHM). The trigger efficiency coefficient (TEC) is investigated. Becouse of absence correct reconstruction procedure for WC+PD system the following algorithm was tested. For lumi branch pure lumi trigger (ET*PD*antiWC) is installed. The trigger efficiency coefficient is mea sured for this trigger and used for HW lumi trigger (PD*ET +5/5 GEV thr esholds). We didn't observe something which is in contradictory with this statement. Usually TEC is equel to 0.902 - 0.918 (beginner and end of lumi run) What is this 8-10%? For total lumi trigger rate-1.5 kHz (typical now) the contribution of double brems events ~0.2%. what we observe on ET_PD plot (53 GeV). Typical rates in PD and ET arms ~ 4.5 kHz => contribution of their random coincidence ~ 3%. The rest 7% are events rejected by coordinate (left part of 21 module). The reason for this rejection is simple: when A.Fomenko tested this rejection all "bad" events with the energy less 24 GeV on sum rec.energy spectra disappea red. So we decrease the error of TEC by non correct rejecting of some part brems events in the left part of 21 module on the following step of 3-sigma energy rejection.

Could somebody from online people producing official luminosity esti- mate once sit down and look what mean all these numbers they are giving and why they are often inconsistent? It was already mentioned several times during summer run. Now again, I compare below "the last word" of A.Usik with what is written in LRTL bank and go to the run summary and is using offline: Run period: 29730 - 31169 Dates: 19/09 - 29/09 Online data HERA produced Lumi: 12.4 nb-1 H1 data taken lumi: 6.8 nb-1 Luminosity for recorded on the IBM H1 data from Run summaries (LRTL bank) 7.9 nb-1 Thus the difference is 6.8-7.9=-1.1 nb-1 ==> 14% We have enough sources for systematic errors, why add extra errors, in addition so big ??? If you need more detailed comparison for some periods: Date H1 runs H1finallumi(online) Lumi for recorded runs(LRTL) ----- -------- ------------------- --------------------------- 22.09 30463-30520 476 mb-1 501 mb-1 ==> 5% 25.09 30738-30790 278 mb-1 322 mb-1 ==> 15% 25.09 30875-30893 172 mb-1 300 mb-1 ==> 54% 28.09 31087-31098 144 mb-1 249 mb-1 ==> 53% 29.09 31164-31169 208 mb-1 328 mb-1 ==> 44% So, could you explain what is what, and what H1 should use for physics? 30.09.1992 ===================== F11LEV === LRTL bank missing.......... Another "nice news": Since evening Sept'29 LRTL bank no longer arrive to the DAQ. Thus, we have no lumi estimate for 2 HERA fillings (300 H1 runs). Indeed, our system + organization is far from to be perfect... 01.10.1992 ===================== H1KSHE === Lumi Run #74 .............. Date: 01/10/92 Collision time: 05:25 - 09:55 !

But becouse of problems in z-vertex,calo.. subsystems H1CDAQ most of time was disabled. 02.10.1992 ===================== H01USA === About trig.eff.coeff.(TEC) Looking in on-line programm for trigger efficiency coefficient calcilation i looked for that there is only energy-rejection on the level 3 sigma and no x-rejection. I think that it means the following conclusion for the present TEC: Now we have TEC = 0.902-918 (90.2 - 91.8 %). 2-3 % is the contribution of random coincidence beetwen ET and PD arms (depends firstly from e,p currents ). The rest 6-7% it is (i think) the good brems events but badly reconstructed (worse then 3 sigma) and rejected on the level 3 sigma. So real TEC now must be ~ 97% instead of ~92%. To exclude this situation we can simply reject events with not the best energy reconstruction. Mainly it is events in the left side of 21 module. So it resonable to provide the x-rejection of this events before energy-rejection. It was proposed more half year ago. And Levonian even calculated the correspondent cross-section. But this idea of rejection on half of module was not the best becouse coordinate resolution in the center of module is the worst and non symmetrical for module 21. For this reason it is better to provide this rejection on the border beetwen 21 and 22 modules. Then calculated cross-section(CS1) will be less of full on factor ~ 0.76. The TEC1 will be also ~0.74. So we will have ~ the same Lumi=~ Rlumi*TEC1/CS1 but with the hihg accurasy in comparison with x-rejection on half of module. For cross-checking we can do the same for x-rejection beetwen 22 and 23 modules( TEC2=~0.55). Must be: TEC1/CS1 == TEC2/CS2. The statistical error of coarse will be the same becouse we use the same Rlumi; only for providing the same statistical accuracy of TEC we must slightly increase the time of measuring of TEC. Now the requirements for accuracy are more higher at least because we monitor specific lumi. And any our error is more visible. 05.10.1992 ===================== H01USA === Lumi Run #75 ..............

Up to now all ETAG-data were reconstructed (as me seems) with old calibration coefficients set (which was put into H1 Data Base "by hand" from calibration with old HV-set. During 101nd ep-run Sasha Usik wrote two Runs (33608 and 33609) which it is possible to use for getting of new calibr.coeff. set. Today it was made the attempt to make this procedure. Now it is possible to put into H1 Data Base new coefficients - if we shall use the old phylosophy of using CC-set (without using of LREC- and LRPC-banks contents and relation coefficient set). e01 = 3.080 3.122 3.146 3.133 2.889 2.860 3.120 e07 = 2.293 3.145 3.370 3.577 3.166 2.726 3.387 e14 = 2.793 2.877 3.281 3.473 3.359 2.901 2.644 e21 = 3.625 3.673 3.370 3.467 3.558 3.486 3.518 e28 = 3.636 3.723 3.761 3.091 2.609 3.009 2.778 e35 = 3.125 3.671 3.292 2.437 2.743 2.531 2.799 e42 = 3.326 3.860 3.317 3.406 4.158 3.276 3.385 p00 = 1.854 1.473 1.132 1.874 1.903 p05 = 2.466 3.475 3.259 3.047 1.800 p10 = 2.544 3.436 3.163 3.093 1.901 p15 = 1.521 1.567 2.231 1.833 1.690 p20 = 1.627 1.668 2.291 2.427 1.960 WaterCounter = 3.817 Start values of CC were chosen as the contents of H1 Data Base (or contents of LREC and LRPC-banks at RunStartRecords) with correction of 15 CC at PD and 19 CC at ET (the changing factor was got from comparison of old on-line CC set and new on-line CC-set - only for channels with "good" weights). It was made calibration step (job is kept at H1KFOM.LUMI93B($F171092) with events from Run 33608 (ET&PD&anti(WC)) - on 75% statistics. Channels e21-e34 at ET had "good"-weights. Channels p05-e08 and p10-p13 at PD had "good"-weights. New CC-set was tested with the same statistics of Run33608 (job is kept at H1KFOM.LUMI93B($A181092). It was made calibration step (job is kept at H1KFOM.LUMI93B($D181092) with events from Run 33609 (ET&PD) - on 81% statistics - for Water Counter spectr. channel calibration. WC-channel had weight near 900. New CC-set was tested with the same statistics of Run33609 (job is kept at H1KFOM.LUMI93B($F181092). All pictures are looked as reasonable. Really it were calibrated only 14 channels for ET and 8 channels for PD. Additionally for 5 channels at ET CC were corrected from high mentioned on-line values comparison (rough correction). The same it was made for 5 channels of PD. Rough correction at high mentioned CC-set was made for e14-e18 and p01-p03,p09,p14,p17,p18. The rest of channels - without changing - old values was used. 18.10.1992 ===================== H1KFOM === Runs 33608,33609,33611 .... A little more detail about three Runs which were recorded at the last half hour of 101st ep-Running (16 Oct.1992) on H1Lumi request to Run Coordinator R.Roosen. Only 2 branches worked at H1CDAQ - Luminosity and CentralTrigger. At Run 33608 only changing of prescale factor for our monitoring trigger bit 94 (ET&PD&anti(WC)) was changed from 8192 up to 0. At Runs 33609 and 33611 it was changed the ETAG-trigger bit and it was changed prescale factor for our monitoring bit 86 - ETAG with Central Trigger global option v - up to 0. Run33609 - ETAG was as ET&PD (rough Lumi-event trigger) Run33611 - ETAG was as WC (trigger of photon arm - at Summer 91 this trigger was the best for searching of bremsstrahlung spectra at photon arm). - this type of trigger (as I know) is interested by V.Andreev N.Gogitidze and Y.Bashmakov.

Yesterday at 18.45 was anniversary of first Lumi Measurements in HERA provided by our subdetector. Instead of drinking we organised kakoi- to seminar. NU NE LOPUHI?! 21.10.1992 ===================== H1KSOL === Integrated Lumi ........... Today morning there was an request from H1 technical coordinator and H1 Run coordinator - F.Brasse and R.Roosen : WE SHOULD MEASURE THE LUMI VALUES FOR SEVERAL PHASES- 1. During tuning for Lumi by HERA - this phase is lost for H1 data taking - and during Lumi Run.These values are indicators of HERA efficiency. 2.For H1 data taking during HERA LUMI RUN we should separate the Lumi accumulated when the trakers are on and when the trakers are off. These values are indicators of H1 efficiency. While the first proposal one can easy implemented it is not obviously for second one,because we must know the status of trakers.Probably it could be supplied by Slow Control. 21.10.1992 ===================== H1KSOL === Lumi Runs #108 - 109.......

Now these releases are renamed as H1LumiOnLineCold and H1LumiOnLineRec- New19old and some time will be kept due to good serving at last monthes and posibility to return to old release if it will be needed. From this day the next releases will run: H1LumiOnlineC - for FIC#1 (last modification - 21 Oct. 1992,18:54) H1LumiOnlineRecNew19 - - for FIC#2 (last modification - 21 Oct. 1992,18:13). The next changings it were made: 1) correction for calculation of H1 gated and H1 gated at LiveTime so called B1 and B11 (experience of last monthes shows that something was wrong sometimes with this integral values - it were fixed negative additions - may be during WarmStart or something else during pause between naighbour H1 Runs). Now it were inhibited the incrementing of this values with another manner - with analyze of bit "Run" at FastCard. 2) it was added the calculation of Luminosity Events Trigger Efficiency Coefficient for restricted ET-apperture -6.6 cm < Xet,Yet < 6.6 cm. Now it is possible to use (mainly by A.Usik) three new values this coefficient: RoughValue - averaged on the last 100 events (near 10 sec.) - address at DPM - B0AAFBCC PureValue - averaged on the last 10000 events (near 1000 sec.) - address at DPM - B0AAFBC4 PureValue1 - averaged on the last 3000 events (near 330 sec.) - address at DPM - B0AAFD68. First comparison of PureValue for full ET-apperture and for restricted gave the next values: 0.891 - for full ET-apperture 0.805 - for restricted ET-apperture. The factor of changing 0.805/0.891 = 0.90. S.Levonian wrote at his H1-LPI-report at May 92 that the factor of cross-section for brems.events changing for restricted ET-apperture is 0.86+-0.01. 3) It was changed the condition of filling histos for "EnergyNew09"- desk accessory. Only events with Xet at restricted apperture of ET will be put into all histos for this desk accessory. 4) It was put into program new values of calibration coefficients - due to last (22.09.92) High Voltage changing and new calibration procedure. New contents of LREC and LRPC-banks at RunStartRecords appeared from Run 34219 (the coefficients at banks are the same as I wrote at message about last calibration procedure at 17.10.92). Remark: it was attempt to introduce the new algorithm of coordinate reconstruction into OnLine. Comparison of coordinate distribution with old and new algorithm at Run 33608 shows that new algorithm adds additional spikes on the cell boundaries for ET&PD&anti(WC)- events. Really new algorithm is better for RoughLumiTrigger - for ET&PD. But now we use PureLumiTrigger as Trigger of Luminosity branch. May be early to introduce new algorithm into OnLine? May be it is needed some additional investigations of this problem? ASKING to H1Lumi-shifters on nearest days: Now we have old and new pairs of releases of OnLineProgram: on the H1Lumi's MacII- NEW RELEASES on the H1Lumi2's MacII- OLD RELEASES If it will be no large problem try to use the new pair of releases - so reload and restart both FICs or any from FICs from H1Lumi MacII (right). After succesful testing of new releases I shall put into H1Lumi2 the new releases too. If it will be appeared the unwaitable situations - go to H1Lumi2 and reload and restart FICs with old releases. 23.10.1992 ===================== F11LEV === On the "new" rec. algorithm So called "new" reconstruction algorithm for the coord. rec. in LUMI counters is working off-line since April'92.

Which runs were recorded 23.10.1992 ===================== H1KSHE === Systematic error source.... Hi dear writers, today i am writer too. Yesterday again, no p-beam but our system shows 2*10**27sm-2s-1 For supposed ~60*10**27sm-2s-1 (if p-beam would available) it means 3% systematic error. So my patience is finished. Here i try to attract the attention for this our problem. From the set of using now correction factors that are involved for calculating luminosity value there is no a factor which capable to subtratct the visible increasing of integrated luminosity during absolute absence of proton beam. According my long time observation it grows for any method of integration. I can say more, it must be so and very probably that the e-current normalised method for subtracting background lumi trigger rate gives now systematic error. This my statment based on the following observations: I never see complete (proportional) correspondence between bunch currents and bunch rates. Disproportion for group of neghborow bunches usualy negligible and bunch trigger rates shape is very closely follows to the bunch currents shape. But separate bunch(pilot) all time has considerable discrepancy with supposed (from e-current value for it) trigger rate value. Some times in the neigborows bunches the rate disproportions are ob- served also. Disproportion for pilot bunch often has aproximatly the value: ~3-7% (less then must be follow from relative current value). Of course first of all i have tried to find any sourse of this uncertainty in H/W. Relevant measurements, and crosscheck are not bring any ideas about H/W influece. So, for this moment the problem is open. The error for integrated luminosity value accoding my measuremets some time reaches 5%. I am ready to accept any this effect explanations including exotic like: These difference may be couse not only different measured devices, but the nature of measured values. In one case the total charge (current) is measured but number of hitting particles is detected for another. Or existing something like tail-clouds of low energy paticles following by electron bunches can be more less explain the effect. But, without dependence of the effect explanation the relevant correction must be done in nearest time becouse of stored now offline data are not complete to do recalculation in future. Probably it will be impossible to do this recalculations due to unstability of the effect. I have an attemt to compensate current-rate disproportion. The main idea was do not use e-bunch current information at all. Realy if you have complete set of trigger rates for collided and pilot bunches relevant rates disproportion(due to e-p collisions) can be easy extracted. When i have first time try to do it during summer lumi run the result was adequate. It was writen special online S/W for simultenios calculating luminosity both "e-current normalised"(usual) and "trigger rates only" methods. The relevant curves for both metods of calculation strictly follows each ather, but small (looks like constant) difference had existed. Firstly i consider this difference due to missing some normalisation factors for "rate" method but seems it is not right. During current run the measuring by both methods has being continued, and now a lot of data are available. One of the conclusions is the "rate" method more protected against systematic error. This my conclusion is based on the fact of very close to zero integral lumi value for "rate" mefod during no collisions or absence proton beam in contrast to "current" method calculation. I think when we will have enough time we can discuss it in details. Now i will not discribe everything in logbook becouse of lack my and you time. I just show some results and calculation algorithm. Here is the time dependence for lumi and integrated lumi for both methods of calculation (Run 90, October 10, 92).

The trigger rates now are very far from any possible H/W effects, so i suppose the reason in something else. I have a lot of graphics where not only this effect is observed. Calculation procedure. For simplisity first i give a list of abriviations for rates of different triggers and rate components of them. Total rates definition: Re = total rate ET trigger Rp = total rate PD trigger Rpe = total rate PD*ET trigger Background - Luminosity rate components definitions: Re = ReB + ReL = rate ET/background/ + ET/lumi/ Rp = RpB + RpL = rate PD/background/ + PD/lumi/ Rpe = RpeB + RpeL = rate PD*ET/background/ + PD*ET/lumi/ Collided - Pilot bunches rate components definitions: Re(p)= Re for pilot bunch, Re(i) = Re for collided b. i = 0,1... Rp(p)= Rp for pilot bunch, Rp(i) = Rp for collided b. i = 0,1... Rpe(p)= Rpe for pilot bunch, Rpe(i) = Rpe for collided b. i = 0,1... (Backgr. - Lumi)*(Coll. - Pilot) rate components: Re = sum(ReB(i) + ReL(i)) + Re(p) Rp = sum(RpB(i) + RpL(i)) + Rp(p) Rpe = sum(RpeB(i) + RpeL(i)) + Rpe(p) For more less correct working LUMI system the next relations must be valid: 1. d(Rp)/Rp = d(Rpe)/Rpe 2. ReL = (RpeL)/A, A - is relative PD acceptance with respect ET arm plus very small value (photo- production, ...). Real value for A is ~0.97 (by Levonian) and as you can see later direct measuring of A is possible. 3. ReB(i)/RpB(i) = Re(p)/Rp(p) If so, the following must be valid also; Rp(i) = RpB(i) + RpeL(i)*Rp/Rpe Re(i) = ReB(i) + A*RpeL(i) RpB(i) = ReB(i)*Rp(p)/Re(p) Now it is not hard to find from this system of equations the RpeL(i) = a bunch(i) luminosity rate value: Rp(i) - Re(i)*Rp(p)/Re(p) RpeL(i) = --------------------------- (I) Rp(i)/Rpe(i) - Rp(p)/(Re(p)*A) If suppose that ReB(i)/Re(p) ratio can be use as the same normalised factor for luminosity background subtraction method, the next two equations can be used for lumi calculation also: Rp(i)*(Re(i) - Rpe(i)/A) ReB(i)/Re(p) = --------------------------- Rp(i)*Re(p) - Rp(p)*Rep(i)/A (II) RpeL =sum( Rpe(i) ) - ( sum(Re(i)/Re(p)) ) * Rpe(p) (wrong) RpeL =sum( Rpe(i) ) - ( sum(ReB(i)/Re(p)) ) * Rpe(p)(right) I prefer (II) procedure becouse of for luminosity definitly equal 0 (no proton beam) correct A value can be find from measurements. Realy influece of A on calculated value of lumi trigger rate for range: A=0.97 - 1.0, is much less then discrepancy between rates calculated by both methods. Finaly i want to say that exist several trigger rates based factors, in addition to background normalisation factor, like relative acceptances for ET,PD,VC which would be good indicator of LUMI system "health" (like specific lumi for HERA). 24.10.1992 ===================== F11LEV === Lumi estimate methods ..... I must admit, that I did not go through the Igor's message very care- fully, but the main idea is clear even from the last formula: the question is what is a best estimator for the background: current ratio I_tot/I_pilot (as it is used presently) or ET trigger rates ratio Re_tot/Re_pilot (as Igor proposes). On my point of view there might be arguments in favour of either of these methods and a'priori it is difficult to decide what is better. One just has to compare in practice the results of the two methods, as Igor started to do. If there will be a clear evidence that one of the methods regularly produces better results this one has to be used as a basic one, while the second as an alternate possibility and cross check. 1) Arguments in favour of present method: it is not evident, that a trigger for the total ET rate reflects correctly background for the lumi events: namely, coincidence between ET and PD. In addition to the photoproduction which is indeed negligible compared to bremsstrahlung there exists a big source of background from the lumi events on the restgas originating NOT AT THE INTERACTION REGION (where PD acceptance is high enough = 97-98%) but rather from the outside of the straight section. These events in principle are not seen by PD, but can be partly accepted by ET and thus contribute ONLY to the Re trigger and NOT to the Rep. Thus, one has to prove that this kind of background behaves the same way for colliding and pilot bunches. 2) Possible explanation of systematic error in present method (and therefore an argument in favour of Igor's method): Present method assumes that Lumi trigger rate from the background (bremsstrahlung on the residual gas) is proportional to the bunch currents ONLY, and ignores the possibility, that in principle pilot bunch may have different behaviour compared to collided ones, as it is known e.g. for the proton beam. If so, than we can over- estimate Lumi trigger rate in case that colliding bunches produce more background per 1 mkA than pilot bunch. However, if lumi trigger is working properly, namely indeed reacts only on the bremsstrahlung events, than it is very difficult to imagine another source of background which is not proportional to the e-current. One of the theoretically possible reasons for different lumi background could be bremsstrahlung from the places where e-beam can slightly touch collimators (just tail at the distance of several sigmas, but quite sufficient to produce few tens Hz of coincidence rate in ET and PD). In this case pilot bunch indeed can produce less background per mkA than colliding ones, espesially during the lumi tuning phase, since due to the beam-beam interaction effect colliding bunches become "broader" than pilot bunch. Anyway, I agree that it would be useful to provide sufficient informa- tion for both methods in order to be able to correct Lumi value later on in case of it happens to be necessary. 24.10.1992 ===================== H1KFOM === Online vs LRTL lumi ....... It was made comparison of OnLine value of H1RunLiveTimeGated Luminosity value (which was got from message of Steve McMahon at H1Run PB) at HERA Running 111. Steve wrote that at this HERA Run: ".... Luminosity run 111 Start Time DT = 16:30 : 23/10/92 End Time DT = 01.08 : 24/10/92 H1 Run Gated = 906 *10**30 cm-2 H1 data = 671 *10**30 cm-2 Start run = 34491 Stop run = 34557 ............" I got Jan Olsson's Integrated Luminosity Values from all 46 H1 Runs of this HERA Running (30 H1 Runs were with non-zero Integrated Lumi Values and after summing off all 30 values the result was 664 *10**30 cm-2. It means that now we are mistaking on 1.04% on low value of Integrate luminosity value. This difference partly could be explain with the next fact: H1LumiOnLine-SW put into H1DataStream the Integrated Luminosity values each 10 sec. But H1 data which are disposed at the last piece of each H1Run (between last LRTL-bank and End-Run-Record) have not Integrated Luminosity values - so we always will have the sum of Jan Olsson's values less then the data from OnLine (LLO or OnLine pictures as summary of each HERA Running). For the 111th HERA Running we had 46 H1Runs - it means that our systematic error was near 100%*(46*10/2)/33240 = (0.69+-0.69)% if You take into account all H1 Runs or near 100%*(30*10/2)/33240 = (0.45+-0.45)% if You get only H1Runs with non-zero Int.Lumi At this expressions: 46 - Numbers of H1Runs at HERA Running 30 - the same but with non-zero Integrated Lumi 10 - time period of putting LRTL-bank into H1 Data Stream (sec); 33254 - number of seconds at 111th HERA Running (from 15:59 up to 01:13) We had 1.04% error at 111th HERA Running - it is a little more then high mentioned explanation. It is needed to continue this type of comparison for future HERA running and to understand all problems and details of this type of systematic error. At the first view (only on 111 HERA Running) the problem of non-equal values at OnLine and LRTLbnk of Integrated Luminosity Value is resolved due to appearence of the last H1LumiOnLineC-release: H1LumiOnlineC - for FIC#1 (last modification - 23 Oct. 1992,13:44) 24.10.1992 ===================== F11LEV === Lumi systematics .......... 1.04% difference is in agreement with the A.M. estimate: the only thing we can say is, that the difference should be between 0% and 1.38% (in the unfortunate case, when for each run complete last 10 sec. piece was lost). For this difference you should not worry too much, since it is easy to correct for: I just have offline add to each run a small amount of lumi according to the time past after the last LRTL bank in the run. 24.10.1992 ===================== H1KSOL === Lumi Runs #112 - 113.......

After installation of new HV set and recalibration of detectors (22.09.92 and 17.10.92) naturally it is needed to tune the Trig.Sums CC. It were tuned calibration constants for Trigger Sums on the data of Run33608 (16.10.92). CCETtrig = 0.003837 GeV/FADCcount (on 13% less) CCPDtrig = 0.005783 GeV/FADCcount (on 5.5% less) CCET+PDtrig = 0.003213 GeV/FADCcount (on 27% less) Job for tuning of this CCs is kept at H1KFOM.LUMI93E(#A241092) data set This new CC will be to work after Run 34642. 24.10.1992 ===================== H1KSHE === sorry for mistake.......... I am very sorry for mistake in formula it was written: RpeL =sum( Rpe(i) ) - ( sum(Re(i)/Re(p)) ) * Rpe(p) --------- but must be: RpeL =sum( Rpe(i) ) - ( sum(ReB(i)/Re(p)) ) * Rpe(p) so, Sergey was absolutly right in her "1) Arguments in flavor of present method" but, for wrong formula. The ratio: sum(ReB(i)/Re(p) means normalisation factor for e-beam only (no p-beam at all). For "rates" method can exist several calcu- lation procedures based on different trigger rates. I just have show two of them, by second one i have try show that it is possible to calculate pilot bunch normalisation factor and then use usual procedure of calculation. By the way, both calculation procedures on practice (real beam conditions) gives the same values for lumi though use the rates of different triggers. 24.10.1992 ===================== F11LEV === What ??? .................. Now I am sorry, but I don't understand last Igor's argument: without presence of proton beam we are not interesting in lumi measurements at all, so sum(ReB(i)/Re(p)) should mean something else. I understood ReB(i) as background rate for the ET trigger in the colliding bunch i. If not, and by ReB(i) you mean rate in case of absence of p-beam, then how can you be sure, that background behavior is the same for e-beam alone and e+p beams? Again, main idea is clear, but answer is not so evident for me (sorry for repeat same thing): the question is what is the best estimator for the background: current ratio I_tot/I_pilot (as it is used presently) or ET trigger rates ratio Re_tot/Re_pilot (as I understand Igor's proposal). 25.10.1992 ===================== H1KFOM === Run #114 ..................

Since you are creating new lumi tables by copying old ones, could you please from time to time check that numbers you are filling in are correct and not just remnants from the previous table? E.g. for run 114 Fomenko gave 10 times more lumi than has been actually obtained. Thank you. 25.10.1992 ===================== H1KSHE === some comments ............. The main idea was to find a procedure for lumi rate calculation which automaticly follows by CURRENT VALUE OF BACKGROUND RATES without any refference to I_tot/I_pilot. Firstly i suppose (after careful experimental check, that particula- rly have done allready) the formula: Rp(i) - Re(i)*Rp(p)/Re(p) RpeL(i) = --------------------------- (I) Rp(i)/Rpe(i) - Rp(p)/(Re(p)*A) where no any evident RpeB subtraction (lumi rate background subtraction). And second way if suppose that ReBtot/Re(p) as well as RpBtot/Rp(p) are equal to RpeBtot/Rpe(p) then after calculating ReBtot or RpBtot (from CURRENT VALUES of Re,Rp,Rpe,Rp(p),Re(p).., e.g. automatic following current background rates,i hope) we can use standart background subtraction procedure. But Re_tot/Re(p) of course CAN NOT BE USED INSTEAD I_tot/I_p. Thank you. 29.10.1992 ===================== H1KFOM === Run #116 ..................

From today it were introduced the new release of H1LumiOnLineRecNew19 Program due to asking of A.Usik to introduce a little correction into On_line calibration procedure (correction of current values of any calibration coefficients will be made only if ratio of deposited energy at cell to reconstructed value of PD,ET or PD+Veto will be more then some option value (default value 0.3)). This procedure now is OFF with default and can be ON from card Coeff&Weights2 of NewFastLumi_Monitor-project (through pushing on radio-button with name "Option1")... only on the H1Lumi MacII (right). The threshold value for CC correction ON can be changed from default value 0.3 on any wanted value through the same card (new field at "NewConstant"-buttom area (lowest)). This release is kept only on the right MacII (H1Lumi). Its data of creation : Sat.,Oct.31.92,16:43. Name - H1LumiOnLineRecNew19.

To all who interested: little remark about Current Luminosity Value calculation: 1) as it was decided earlier (on some reasons) the calculated value of Current Total Luminosity was not multiplied on Trigger Efficiency Coefficient so all Lumi values which we had at July and Sept.-Nov.92 data taking seance of H1 obviously are a little more then real (on value of 1./PLTEFF); 2) at all previous calculations of Luminosity Values it was used the value of total cross section for brems. events at our apperture (for ACCC=1.0, Ee=26.7 and Ep=820.0 GeV) as 23.8 mb (which was calculated with FAST_MC) but not 25.0 (which was calculated with DETAILED MC) - so all luminosity values are a little more then real again (near 5%). We must decide for the next seances how we will use this two digits at Luminosity calculations. 01.11.1992 ===================== H01USA === Remark about Lumi Values... It is not concern the values of lumi and specific lumi presented on TV monitors, H1,HERA displays, and correspondently on printed history, in check list and computer logbook. It is correspondent to cross-section 25.0 and so called trigger efficie ency coefficient = 0.97. The correspondent integrated values are also available in H1_TV application, but on inheritance reasons the integrated values from fic programm are presented. Now in the last version of H1_TV in calculation of lumi instead of ratio 0.97/25 the ratio 0.834/(25.0*0.86) is used which are equal. Here 0.834/0.86 is really trigger efficiency coefficient, and 0.86 - normalized coefficient of ET acceptance relatively to full acceptance of ET for which we have trigger rate and calculated cr.-s. (25.0). What is this ~3%? There are two contributuon: firstly it is random coincidence with the frequency fe*fg/F for every bunch, where fe, fg - total rates in electron and gamma arms, F - 56 kHz 'one bunch revolution rate'; secondly - it is some dirty events (seems very small contribution); So ~0.97 it is really the efficiency of trigger,BUT if we improve this trigger,f.ex. adding hw rejection on ET+PH on the level 3 sigma, we'll cut the random coincident events, but we'll cut also some good brems events on the ET border because of big energy leakeage. SO: it is not necessary to use ET+PH cutting in the hw trigger. Topological hw trigger will not have the same coordinate resolution as in on-line reconstruction so we cannot use it for rejection of border events. So it seems It is enough to use the present ideology, only to change x,y-cutting on the level +/- 55mm, becouse coordinate resolution on the level +/- 66 mm is not symmetrical (only one neigbour module) and as result ET acceptance normalised coefficient is slightly shifted relatively 0.86. 02.11.1992 ===================== H1KSOL === Lumi Run #124 ............

Main updates are: 1) Calibration procedure and Trigger Efiiciency Calculation now will be inhibited with the same Inhibit-button which inhibited Luminosity measurements at all previous releases; 2) Current values of calibration coefficients will be kept at DPM at the same time when new LREC- ans LRPC-banks are prepared for H1DataFlow - due to this updating it is possible now after reboot of FIC#2 to continue calibration with the last value of CCs; 3) Little additions was made into monitoring facilty which are used with EnergyNew_b09 - desk accessory. It is possible now to play with this desk accessory for investigations of Xet-cuts influence on energy distribution spectra at detectors. New release is kept only on H1Lumi MacII (right) up to finish of testing. Its creation date: 04 Nov. 1992, 00:02. A little changing was made at the card "Coeff&Weights" and "LumiMeasuremants1" of the NewFastLumiMonitor-project which is kept only at H1Lumi MacII (right) - up to finishing of testing. This release is the step on the way of involving of Trigger Efficien- cy Coefficient accounting at the Luminosity Measurements. Note: it is needed to note that at all previous looking for values of Trigger Efficiency Coefficient it was used the energy resolution of our detector (sigma) - as 1.3 GeV. Really this value 0.77-0.80 (from last measurements). 04.11.1992 ===================== H1KFOM === Lumi Run #127 ............ Date: 03/11/92 Collision time: 17.53 - 23.14 !

It was the next attempt to make ep-collisions with Ee=12 GeV and Ep=820 GeV at 23:15 08 November 1992. All attempts to make luminosity were unsuccesful at both interaction points (H1 and ZEUS). At 0:51 e-beam was lost. After 15 min. p-beam was debunched due to RF-trip. At this attempt Ip was 2.25 mA, Ie was 1.7mA at 23:15 and was decre- mented during lumi optimization up to 1.2 mA (at 0:51). At 1:25 - preparing restart. Luminosity operation will stop at 6:00 h. 17.11.1992 ===================== H1KSOL === Dosimeters ................ During last Lumi Run (21.08.92 - 08.11.92) four dosimeters were exposed to radiation on the Lumi detectors (see Lumi Logbook part 4).The doses value obtained are the following: Dosimeter # Dose value(Gy) Position 1 700 On the front face of ET(el.#21) 2 750 In front of Dosimeter #1 3 11 On the front face of PD (el.#12) 4 26 In front of Dosimeter #3 During this Lumi Run Lumi Detectors were practically always in working position exept of a few machine shifts for e-life studies. One should remember that during the second half of Lumi Run the position of gamma beam on PD was always 10-15 mm lower central layer of PD.So dose values for #3 and #4 should be multiplyed by 2. The average e- and p currents for this LumiRun are (estimated from the one month of HERA operation : 21.09-19.10):Ip=2.4ma,Ie=1.3ma. The corresponding design values are Ip(d)=163ma,Ie(d)=58ma. Assuming that background conditions are proportional to the product of p and e currents one can easy to get the dose values for nominal condition at the working position of Lumi detectors: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! For ET : Dose value = 2.3*10**6 Gy ! ! For PD : Dose value = 1.6*10**5 Gy. ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! That is for 2.5 month of HERA operation and for assumption that detectors are all time in working positions. H.Dinter in Interner Bericht DESY D3-56 1985 "Synchrotronstrahlung in HERA - tunnel" cites the following dose values for about the same positions as in our case : For ET - 6*10**5 Gy For PD - ~10**4 Gy these values are calculated for average e current 25 ma,e energy 30 Gev and operation 4000 h/year and only for synchrotron radiation. The dose value for ET is for the case of magnet dipole so it is overestimated for our case I would say by factor 5 - 10.
