** I checked the Raster for the summer 2019 data. It looks ok to me. I did not see any slightly tilting issues that Ali saw earlier.
21 547 Ali Usman
** I do not think that we will need to make any changes to the Raster in the summer 2019 data.

** 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
37
** It looks like the efficiency is less from the production data (Q2 = 0.38 GeV2, High e).
38
** I'll take a look at the heep coin data in this run period of the experiment and get the efficiency. 
39
** 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.

54
** 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.
55
** 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
145
** 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.

** A new subroutine has been added for the hcana variable calculations in SIMC, this is ongoing.
310
** Plots of right/left/center for each physics setting have been added, including efficiencies and t-bin plots (no diamond cuts yet!). These plots show the input to Bill's code for comparison. These need to be updated with Ali's updates so a new set of replays will need to be analyzed.

** 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.
336
** 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.
337
** 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.

** 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%.
383
** 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.
384
** 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.
416

** 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 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.

782
** 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.

** PID efficiency script is coming together
1010
*** Tighter cuts and cuts on timing, beta, etc. will be needed for cleaner electron cuts
1011
*** Hcal cut should be changed to cut around the mean normalized value instead of cutting above or below it only. This will assure electrons aren't lost.

1067 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.
1068 71 Richard Trotta
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
1069
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
1070
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
1071
** We can begin looking forward towards efficiencies. 
1072
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
1073
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways. 
1074

1076
** Has been looking at the calorimeter as well. 
1077 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.

1108
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)

* SHMS Reference Time Amplitude Cuts(Stephen)
1126
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
1127
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1128
** This is a temporary fix to "ghost-bands" and cross talk
1129
*** Although for HG there is still a small peak. The hodoscope is fine.
1130
** The time window is easier to set now.
1131
** DC has been fine (since it uses TDC)
1132
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
1133
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated

* Peter's hcana fixes for reference time (Richard)
1136 67 Richard Trotta
** Peter implemented changes to hcana
1137
** Two major issues...
1138 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1139 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1140 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)
1141 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1142
** Richard has been checking for bugs in the code. 
1143
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
1144
1145 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
1146 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
1147 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
1148 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

1285
** 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
1286
** 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.

** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
1343
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
1344
** *Next steps:*
1345 5 Richard Trotta
*** Check tracking efficiency

* *Global comments on Luminosity Scans (so far)*
1348 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.
1349 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
1350
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
1351
** Uncertainties on current
1352
** Detector calibrations
1353 1 Richard Trotta
** HMS vs. SHMS

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
1356
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1357
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1358
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1359
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1360
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1361 1 Richard Trotta
** *Next steps:*
1362 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)
1363 35 Stephen Kay
1364
* Yield normalized ratios from SIDIS (Hem)
1365
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1366
** *Next steps:*
1367 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
1376
** Shown is a scaler-based analysis using scalers from report file and from ROOT tree - the values are different, why that is has to be checked
1377
** Notes on efficiencies in report file:
1378
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1379
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1380
*** Tracking efficiency needs to be checked
1381
*** 3/4 trigger efficiency seems ok
1382
* Discussion luminosity scan analysis (later scan) - Ryan
1383
** Fewer carbon runs than earlier scan
1384
** Shown is a tracking-based analysis using data from the ROOT trees
1385 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
1386 35 Stephen Kay
* SIDIS analysis - Hem
1387
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1388
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1389
* Analysis of exclusive events in SIDIS - Samip
1390
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1391
** Ongoing work on implementing coincidence time into tree
1392
* Discussion of run plan, and in particular possible low Q2/low energy
1393
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1394
** 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
1395
** Garth will put this together in a draft email

1413 18 Richard Trotta
1414 35 Stephen Kay
*  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.
1415
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
1416
* Discussion of Richard's slides on run plan kinematics and preparations -
1417
** 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
1418
** 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
1419
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
1420
** kinematics plots W-Q2 show that still need to do some optimization
1421
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
1422
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
