** 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). 
269
** 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.

622
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
623
** We can begin looking forward towards efficiencies. 
624
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.

679
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling

681
*** Although for HG there is still a small peak. The hodoscope is fine.
682
** The time window is easier to set now.
683
** DC has been fine (since it uses TDC)
684
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")

* Peter's hcana fixes for reference time (Richard)
688 67 Richard Trotta
** Peter implemented changes to hcana
689
** Two major issues...
690 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
691 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
692 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)
693 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
694
** Richard has been checking for bugs in the code. 
695
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
696
697 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
698 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
699 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
700 62 Richard Trotta

834
** resolving differences between his analysis and Richard's
835
836
* Richard
837
** 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
838
** 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 (Richard, Ryan)
853 111 Richard Trotta
** Carbon scan from April seems consistent with no boiling, LH3 and LD2 show deviation from unity, should check effect of EDTM events on efficiencies
854 35 Stephen Kay
** Carbon scans from January (low rates) have large deviations from unity, in particular behavior at higher currents (>40uA), e.g. cpu dead time, that is not yet understood
855

877
* Luminosity Scans January 2018 (Richard)
878
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
879
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
880
** Efficiency calculation was investigated in detail and applied using scalers from trees
881
** Results for carbon (normalized to 30uA) show large variation - need to understand
882
** *Next steps:*
883
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
884
*** Check stability of pre-scale (Ryan saw changes within runs)
885
*** Check if detector calibrations for runs are implemented correctly
886
*** Analyze with Ryan's cuts
887 1 Richard Trotta
888 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
889
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
890
** Tracking-based analysis for runs 2073-2095
891
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
892
** Included most recent detector calibrations in replay of these runs
893
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
894
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
895
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
896
** *Next steps:*
897 5 Richard Trotta
*** Check tracking efficiency
898 35 Stephen Kay
899
* *Global comments on Luminosity Scans (so far)*
900 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.
901 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
902
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
903
** Uncertainties on current
904
** Detector calibrations
905 1 Richard Trotta
** HMS vs. SHMS
906 35 Stephen Kay
907
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
908
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
909
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
910
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
911
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
912
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
913 1 Richard Trotta
** *Next steps:*
914 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)
915 35 Stephen Kay
916
* Yield normalized ratios from SIDIS (Hem)
917
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
918
** *Next steps:*
919 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

927 35 Stephen Kay
* Discussion luminosity scan analysis (earlier scan) - Richard
928
** 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
929
** Notes on efficiencies in report file:
930
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
931
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
932
*** Tracking efficiency needs to be checked
933
*** 3/4 trigger efficiency seems ok
934
* Discussion luminosity scan analysis (later scan) - Ryan
935
** Fewer carbon runs than earlier scan
936
** Shown is a tracking-based analysis using data from the ROOT trees
937 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
938 35 Stephen Kay
* SIDIS analysis - Hem
939
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
940
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
941
* Analysis of exclusive events in SIDIS - Samip
942
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
943
** Ongoing work on implementing coincidence time into tree
944
* Discussion of run plan, and in particular possible low Q2/low energy
945
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
946
** 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
947
** Garth will put this together in a draft email

966 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.
967
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
968
* Discussion of Richard's slides on run plan kinematics and preparations -
969
** 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
970
** 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
971
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
972
** kinematics plots W-Q2 show that still need to do some optimization
973
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
