** Carlos and I found the error in the HMS scaler rate and slope. I was previously doing some testing of ELREAL vs ELCLEAN and I never reverted my testing from ELCLEAN. Once I changed the variable back to ELREAL, the rates and trends match.

** HMS Calorimeter efficiency study. attachment:Vijay_May11_2023.pdf
20
** It looks like the efficiency is less from the production data (Q2 = 0.38 GeV2, High e).
21
** I'll take a look at the heep coin data in this run period of the experiment and get the efficiency. 
22
** Hopefully that's number, the efficiency from heep coin data, will be reliable to correct the inefficiency of the detector and correct the data run by run.

** Most of the bad runs have been resolved although there are still a few issues I am sorting out. I also have some plots of the boiling corrections that need to be updated.
33
** I talked with Jacob last week and he checked my luminosity calculations and they seem fine. Carlos and I are meeting tomorrow at 11 am to try and figure out our discrepancies.
34
** Found a possible cut issue with the proton peak where cuts were not being properly applied. This is still early in checks.

** Carlos has been working on the rate dependence issue for the luminosity scans that Casey and I have been seeing. He came to a similar conclusion as me that there will need to be a correction factor that we all agree on that will need to be applied. We are meeting on Monday to discuss things further. "See his slides on the docDB":https://hallcweb.jlab.org/doc-private/ShowDocument?docid=1206
120
** I think I have tracked down the odd issues with right setting that I have been seeing for most energies. I am not sure why, but it seems that something is going wrong with the replays. I tried rerunning them, but the issue has persisted. My initial guess is that it may be an issue with the TDC cuts, since the coin time distributions were looking off previously.

267
** We are a month behind at this point and Bill has finally responded to my questions so I am going to fully concentrate on getting cross sections before the Hall C collaboration meeting in January so that Nathan can present them. I am setting a soft deadline of January 6th to get him early results but will continue to push for cross sections by the talk.

** Fits for lumi scans look great for HMS across the board. SHMS no track also look pretty good but tracking still needs work. Ali has adjusted the tracking parameters in the replay which should help things. Signs of boiling are also now evident in HMS for some runs.
311
** Odd issue with the yields going on that I need to discuss with Bill. It seems to be a cut discrepancy that is eliminating events, I may be missing a cut that he has hidden somewhere. Besides this, the cross-section code is being edited for HeeP so we can get some cross-section plots on this soon.
312
** I found a script for raster calibrations. The script is being fixed as it is currently a bit of a mess.

** Heep Coin Offset study using Peter Bosted's correction factor for HMS central momenta. The results from 8.2 and 10.6 GeV improved after applying the offset whereas 6.2 over corrects the distributions as they are already looking good with no offset. Data and SIMC comparison look very good for W distribution but doesn't perfectly match for missing variables.

** Regarding Ali's work on the Pc offsets at high momentum, I referenced the delta corrections I made early last year. In EPICS, the NMR did not appear to be locked and in the middle of the scan, the NMR was changed. Slide 15 has the offsets to the central momentum, Pc.

** Luminosities are looking very nice. These now include the ones Peter pointed out that were taken during SIDIS. Nearly all e-e runs are under 5%.
358
** I have debugged all of the issues I was having with Bill's code. I am now in the process of merging the two frameworks which is mainly just making names, conventions, etc. consistent.
359
** I have been writing up some questions for Bill next week when he presents. I'd like to also have these two frameworks pretty much merged by then.

** Fixed some issues with the luminosity scripts with updated replay and analysis script. The biggest issue was the really low beam on times which came from BCM4a being called by accident in some cases instead of BCM1.
391
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
392
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.
393
** Tanja sent me some awesome fpi2 raster correction documents as well as procedures for verifying the beam and target positions. I am in the process of reading through/beginning these procedures. A Redmine wiki page will be linked when completed.

** Lumi SHMS tracking is still showing the trend from 9/8. It was found that the lumi replay script is not updated with many of Ali and Richard's most recent changes. These changes are being applied and a set of new replays will be done.
411 390 Richard Trotta
** Bill's cross-section code is broken into two major parts. The root analysis part, which takes all the yields, uncertainties, etc., is nearly complete with the connecting ltsep framework script finishing up. The second part, where many of the final plots and cross-sections are done, is a hard-coded mess. Richard is in the process of making this more dynamic. This aspect will take more time but the root analysis part is the bulk of the analysis anyways.

** Heep Coin analysis for high Q2 KaonLT data (6.2, 8.2, 10.6 GeV beam energy) has now all the efficiencies/live times applied. The results for all 3 beam energies are looking very good. Data/SIMC ratios are agreeing very well (< 3%) and the shapes are matching up nicely. Next step is to finalize offsets for both low and high Q2 KaonLT data. Also proton absorption correction and target boiling needs to be applied.

** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
464
** I have decided to give a second pair of eyes to Ali's hcana vs simc calculation investigation. It is concluded that the broad peaks of the hcana are likely caused by the secondary particle calculation which is gathered from the spectrometer track info. 
465
** Corrections to the simc pmiss components have been added to the fortran code which corrects for a minus sign that is in hcana but missing from simc.

** The currents were adjusted from 1-10 uA with little effect on the EDMTLT but proper changes to the CPULT. The replay bcm cut script developed by Sanghwa was also analyzed to see if it may be causing the issue but it had the same effects. There was also a small error in the code found where T.coin.pEDTM.tdcTimeRaw was incorrectly written as T.coin.pEDTM.tdcTime.

** I found an issue with the replay scripts used where the EDTM was not being properly registered. There is a discrepancy between two replay scripts depending on what the Decode_master is set to (i.e. ALL_events vs ALL_events_NO_EDTM). 
757
** The explicit calculation of the prescale has hit a snag because of the differences between 6 GeV and 12 GeV. I contacted Mark Jones, who explained there are significant differences in the ADC gate between the two eras (which my own findings confirmed). I have contacted Brad for further input.

* Garth and Stephen were in the most recent SIDIS meeting
1019
** Wit had lots of hcana changes but they seem to be critical to our work 
1020
*** Changes such as new detector classes
1021 1 Richard Trotta
** Hopefully Wit will present these in the next commissioning meeting
1022
1023 77 Richard Trotta
* Stephen improved wiggles but still prevalent
1024 74 Richard Trotta
1025
* Richard finished HGCer calibrations, he concluded that the online parameters are sufficient
1026
** He also has been looking at SHMS calorimeter calibrations but has had issues running the scripts. Most likely a pathing issue.
1027
** The "tasks":https://redmine.jlab.org/projects/kltexp/wiki/Analysis_Tasks page has been updated with a section for efficiencies. 
1028
*** A PID efficiency script is currently being developed and hopefully should have some plots for our next meeting.

1037
** DC SHMS, small-angle has poor performance
1038
*** Tighter cuts or PID (currently only looks for electrons)
1039

1040
1041
* Richard
1042 1 Richard Trotta
** The calibrations are nearing completion with only the HG Cherenkov and SHMS calorimeter yet to be finished. There are also smaller issues with some DC and HMS calorimeter runs.
1043 71 Richard Trotta
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
1044
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
1045
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
1046
** We can begin looking forward towards efficiencies. 
1047
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
1048
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways. 
1049
1050
* Hem
1051
** Has been looking at the calorimeter as well. 
1052 70 Richard Trotta
** He has seen the second band in the spectra for some runs, we suggested further looks into HMS hodoscope and subsequently reference times. A recalibration will need to be performed.

* Timing update (Stephen)
1077
** Reference times between Richard and Stephen are very similar and the GitHub is updated accordingly
1078
** Richard is going to add the trigger time cuts once the fall runs are finished (by end of week)
1079
** First pass of detector reference time parameter files finished
1080 1 Richard Trotta
1081 68 Richard Trotta
* Peter's hcana code (Richard and Stephen)
1082
** Peter's code does not remove ghost bands (already known), but now Stephen is seeing a strang horizontal band for just SHMS hodoscope 2D plots
1083
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
1084
** This means we still need the reference time amplitude cut with Peter's code but using just the amplitude cut with Mark's latest version of hcana should be sufficient for calibrations.
1085
1086
* Calibrations were decided to be done once per shift
1087
1088
* Next meeting schedule...
1089 127 Richard Trotta
** Small meetings Nov 12 and Nov 19 (at 3pm EST) so Richard and Stephen can iron out the timing and calibrations
1090
** November 26 (at 3pm EST) will be a larger meeting. 
1091 68 Richard Trotta
*** This is the rough deadline we made for finishing up calibrations. 
1092
*** This should be sufficient for all detectors (although hodoscope and HG which may persist). The ultimate goal is for all calibrations to be finished up before Winter break!!

* SHMS Reference Time Amplitude Cuts(Stephen)
1101
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
1102
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1103
** This is a temporary fix to "ghost-bands" and cross talk
1104
*** Although for HG there is still a small peak. The hodoscope is fine.
1105
** The time window is easier to set now.
1106
** DC has been fine (since it uses TDC)
1107
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
1108
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated
1109
1110 1 Richard Trotta
* Peter's hcana fixes for reference time (Richard)
1111 67 Richard Trotta
** Peter implemented changes to hcana
1112
** Two major issues...
1113 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1114 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1115 1 Richard Trotta
## Timing offset between EL-REAL and 3/4 is 130 ns which causes junk tracks at high SHMS rates (~6% of the time)
1116 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1117
** Richard has been checking for bugs in the code. 
1118
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
1119
1120 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
1121 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
1122 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
1123 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

* Richard
1260
** Discussed with Mark Jones and is cross checking his January luminosity scan analysis against Mark's. Realized that BCM calibrations (gains, offsets etc) are different - currently working on fixing that, presents current results - low curent point is ~10% below unity, discussion that this seems to indicate that BCM offsets are the issue as low current points would be most sensitive, is planning to also double-check the BCM calibration procedure - had discussion with Dave Mack at JLab
1261
** Presents a script developed for luminosity scans that determines yields for a run number input on command line. Discussion this could be good to adapt for kaon counting during experiment.

* Luminosity Scans January 2018 (Richard)
1301
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1302
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1303
** Efficiency calculation was investigated in detail and applied using scalers from trees
1304
** Results for carbon (normalized to 30uA) show large variation - need to understand
1305
** *Next steps:*
1306
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1307
*** Check stability of pre-scale (Ryan saw changes within runs)
1308
*** Check if detector calibrations for runs are implemented correctly

1313
** Tracking-based analysis for runs 2073-2095
1314
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
1315
** Included most recent detector calibrations in replay of these runs
1316
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1317
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
1318
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium

* *Global comments on Luminosity Scans (so far)*
1323 1 Richard Trotta
** April 2018 scans show hydrogen and deuterium target boiling on level of 3-4%, Carbon is consistent with no boiling, as expected - based on description, new targets are expected to have less boiling than those used previously, e.g. in FPI2. Double check this.
1324 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
1331
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1332
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1333
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1334
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1335
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1336 1 Richard Trotta
** *Next steps:*
1337 2 Richard Trotta
*** Look for a run with kaon momentum closer to 3 GeV/c (aerogel threshold is ~3 GeV/c for kaons for n=1.015)
1338 35 Stephen Kay
1339
* Yield normalized ratios from SIDIS (Hem)
1340
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1341
** *Next steps:*
1342 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1354
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1355
*** Tracking efficiency needs to be checked
1356
*** 3/4 trigger efficiency seems ok
1357
* Discussion luminosity scan analysis (later scan) - Ryan
1358
** Fewer carbon runs than earlier scan
1359
** Shown is a tracking-based analysis using data from the ROOT trees
1360 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
1361 35 Stephen Kay
* SIDIS analysis - Hem
1362
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1363
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1364
* Analysis of exclusive events in SIDIS - Samip
1365
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1366
** Ongoing work on implementing coincidence time into tree
1367
* Discussion of run plan, and in particular possible low Q2/low energy
1368
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1369
** For pion form factor and LT, have two possible settings that can use the prescribed beam energies: Q2=1.45 and 0.35 GeV2 - prioritize towards the higher Q2 as not as sensitive to offsets
1370
** Garth will put this together in a draft email

*  Discussion of Andres' slides on elastic W calculation in hcana - initial issue with negative W values seems to be due to outdated information in standard.kinematics file. Additional investigation ongoing.
1390
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
1391
* Discussion of Richard's slides on run plan kinematics and preparations -
1392
** everyone agrees that in general want to have as many L/T cross section separations as possible in a robust run plan balancing statistics vs. systematics
1393
** before actual run may want to do a 3D optimization in all kinematic variables to get the best possible delta(epsilon) for the L/T separations
1394
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
1395
** kinematics plots W-Q2 show that still need to do some optimization
1396
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
1397
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
1398 26 Richard Trotta

* *Action Items:*
1400
** Post slides/notes from this meeting and procedure to set up hcana in Redmine (Tanja)
1401
** Update run sheet and kinematic optimization for W/Q2 (Garth)
1402
** Circulate elastic calculations for kinematic settings (Samip)
1403
** Continue investigation of elastic data and run plan kinematics (Andres/Richard)
1404
** Test software installation instructions (Pete)
1405
** Draft email to JLab management about need for small angle beam pipe - need to have HMS minimum angle of less than 13 degrees for kaon L/T separations (Tanja)
