** The second thing that I have for this meeting is to understand how to get total events in calculating the scaler yield. From Carlo's thesis, it seems that he used the scaler current variable (just integrating it) to get the total scaler events for the scaler yield. I've attached his thesis pages. Please see the attachment. He did not even mention the EDTM subtraction. Therefore, first I would like to understand this (how to get total events for the scaler yield) before making any conclusions from the plots. attachment:Carlo_scaler_yield.pdf

** 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.

** 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.
54
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
55
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.
56
** 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.
74 390 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.

** 3.6 and 3.9 GeV data do NOT have the angle offsets. This has been established in the study.
124 370 Richard Trotta
** I've plotted the offsets vs SHMS central momentum. Plots are attached in the attached pdf file.
125
* Richard
126
** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
127
** 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. 
128
** 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). 
420
** 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.

** 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.
706 71 Richard Trotta
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
707
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
708
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
709
** We can begin looking forward towards efficiencies. 
710
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
711
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways. 
712
713
* Hem
714
** Has been looking at the calorimeter as well. 
715 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)
740
** Reference times between Richard and Stephen are very similar and the GitHub is updated accordingly
741
** Richard is going to add the trigger time cuts once the fall runs are finished (by end of week)
742
** First pass of detector reference time parameter files finished

744 68 Richard Trotta
* Peter's hcana code (Richard and Stephen)
745
** 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
746
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
747
** 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.
748
749
* Calibrations were decided to be done once per shift
750
751
* Next meeting schedule...
752 127 Richard Trotta
** Small meetings Nov 12 and Nov 19 (at 3pm EST) so Richard and Stephen can iron out the timing and calibrations
753
** November 26 (at 3pm EST) will be a larger meeting. 
754 68 Richard Trotta
*** This is the rough deadline we made for finishing up calibrations. 
755
*** 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)
764
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
765
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
766
** This is a temporary fix to "ghost-bands" and cross talk
767
*** Although for HG there is still a small peak. The hodoscope is fine.
768
** The time window is easier to set now.
769
** DC has been fine (since it uses TDC)
770
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
771
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated
772
773 1 Richard Trotta
* Peter's hcana fixes for reference time (Richard)
774 67 Richard Trotta
** Peter implemented changes to hcana
775
** Two major issues...
776 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
777 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
778 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)
779 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
780
** Richard has been checking for bugs in the code. 
781
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
782
783 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
784 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
785 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
786 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

911
* Adapt luminosity scan script to calculate kaon yields by run number for use during experiment by shift crew - has to be simple to use. (Richard)
912
* Develop trigger/detector checkout plan (Tanja, initial draft)
913
** Are all experts available at run start, experts needed: coincidence timing , Harp Scans, BCM calibrations, ...
914
* Find out from JLab what the anticipated settings are for limit switches for both spectrometers and for separation angle in between them. Also find out what magnet cycling procedure should be used for L/T quality separation data (Tanja)

920
** resolving differences between his analysis and Richard's
921
922
* Richard
923
** 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
924
** 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)
964
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
965
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
966
** Efficiency calculation was investigated in detail and applied using scalers from trees
967
** Results for carbon (normalized to 30uA) show large variation - need to understand
968
** *Next steps:*
969
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
970
*** Check stability of pre-scale (Ryan saw changes within runs)
971
*** Check if detector calibrations for runs are implemented correctly
972
*** Analyze with Ryan's cuts
973 1 Richard Trotta
974 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
975
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
976
** Tracking-based analysis for runs 2073-2095
977
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
978
** Included most recent detector calibrations in replay of these runs
979
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
980
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
981
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
982

986 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.
987 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
988
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
994
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
995
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
996
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
997
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
998
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
999 1 Richard Trotta
** *Next steps:*
1000 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)
1001 35 Stephen Kay
1002
* Yield normalized ratios from SIDIS (Hem)
1003
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1004
** *Next steps:*
1005 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
1014
** 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
1015
** Notes on efficiencies in report file:
1016
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1017
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1018
*** Tracking efficiency needs to be checked
1019
*** 3/4 trigger efficiency seems ok
1020

1022
** Shown is a tracking-based analysis using data from the ROOT trees
1023 111 Richard Trotta

1025
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1026
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1027
* Analysis of exclusive events in SIDIS - Samip
1028
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1029
** Ongoing work on implementing coincidence time into tree
1030
* Discussion of run plan, and in particular possible low Q2/low energy
1031
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1032
** 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
1033
** Garth will put this together in a draft email

* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
1054
* Discussion of Richard's slides on run plan kinematics and preparations -
1055
** 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
1056
** 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
1057
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
1058
** kinematics plots W-Q2 show that still need to do some optimization
1059
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
1060
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
