** 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). 
263
** 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 HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
617
** We can begin looking forward towards efficiencies. 
618

672

673
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling

675
*** Although for HG there is still a small peak. The hodoscope is fine.
676
** The time window is easier to set now.
677
** DC has been fine (since it uses TDC)
678
*** 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)
682 67 Richard Trotta
** Peter implemented changes to hcana
683
** Two major issues...
684 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
685 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
686 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)
687 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
688
** Richard has been checking for bugs in the code. 
689
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
690
691 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
692 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
693 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
694 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

828
** resolving differences between his analysis and Richard's
829
830
* Richard
831
** 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
832
** 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)
847 111 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
848 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
849

871
* Luminosity Scans January 2018 (Richard)
872
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
873
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
874
** Efficiency calculation was investigated in detail and applied using scalers from trees
875
** Results for carbon (normalized to 30uA) show large variation - need to understand
876
** *Next steps:*
877
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
878
*** Check stability of pre-scale (Ryan saw changes within runs)
879
*** Check if detector calibrations for runs are implemented correctly
880
*** Analyze with Ryan's cuts
881 1 Richard Trotta
882 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
883
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
884
** Tracking-based analysis for runs 2073-2095
885
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
886
** Included most recent detector calibrations in replay of these runs
887
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
888
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
889
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
890
** *Next steps:*
891 5 Richard Trotta
*** Check tracking efficiency
892 35 Stephen Kay
893
* *Global comments on Luminosity Scans (so far)*
894 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.
895 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
896
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
897
** Uncertainties on current
898
** Detector calibrations
899 1 Richard Trotta
** HMS vs. SHMS
900 35 Stephen Kay
901
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
902
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
903
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
904
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
905
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
906
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
907 1 Richard Trotta
** *Next steps:*
908 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)
909 35 Stephen Kay
910
* Yield normalized ratios from SIDIS (Hem)
911
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
912
** *Next steps:*
913 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

921 35 Stephen Kay
* Discussion luminosity scan analysis (earlier scan) - Richard
922
** 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
923
** Notes on efficiencies in report file:
924
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
925
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
926
*** Tracking efficiency needs to be checked
927
*** 3/4 trigger efficiency seems ok
928
* Discussion luminosity scan analysis (later scan) - Ryan
929
** Fewer carbon runs than earlier scan
930
** Shown is a tracking-based analysis using data from the ROOT trees
931 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
932 35 Stephen Kay
* SIDIS analysis - Hem
933
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
934
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
935
* Analysis of exclusive events in SIDIS - Samip
936
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
937
** Ongoing work on implementing coincidence time into tree
938
* Discussion of run plan, and in particular possible low Q2/low energy
939
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
940
** 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
941
** Garth will put this together in a draft email

960 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.
961
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
962
* Discussion of Richard's slides on run plan kinematics and preparations -
963
** 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
964
** 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
965
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
966
** kinematics plots W-Q2 show that still need to do some optimization
967
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
