** 3.6 and 3.9 GeV data do NOT have the angle offsets. This has been established in the study.
59 370 Richard Trotta
** I've plotted the offsets vs SHMS central momentum. Plots are attached in the attached pdf file.

61
** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
62
** 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. 
63
** 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.

** 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). 
355
** 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.

## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
712 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
713 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)
714 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
715
** Richard has been checking for bugs in the code. 
716
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
717
718 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
719 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
720 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
721 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

*Analysis Updates:*
853
854

855
** resolving differences between his analysis and Richard's
856
857
* Richard
858
** 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
859
** 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)
899
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
900
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
901
** Efficiency calculation was investigated in detail and applied using scalers from trees
902
** Results for carbon (normalized to 30uA) show large variation - need to understand
903
** *Next steps:*
904
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
905
*** Check stability of pre-scale (Ryan saw changes within runs)
906
*** Check if detector calibrations for runs are implemented correctly
907
*** Analyze with Ryan's cuts
908 1 Richard Trotta
909 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
910
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
911
** Tracking-based analysis for runs 2073-2095
912
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
913
** Included most recent detector calibrations in replay of these runs
914
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
915
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
916
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
917
** *Next steps:*
918 5 Richard Trotta
*** Check tracking efficiency
919 35 Stephen Kay
920
* *Global comments on Luminosity Scans (so far)*
921 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.
922 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
923
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
924
** Uncertainties on current
925
** Detector calibrations
926 1 Richard Trotta
** HMS vs. SHMS
927 35 Stephen Kay
928
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
929
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
930
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
931
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
932
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
933
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
934 1 Richard Trotta
** *Next steps:*
935 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)
936 35 Stephen Kay
937
* Yield normalized ratios from SIDIS (Hem)
938
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
939
** *Next steps:*
940 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

948 35 Stephen Kay
* Discussion luminosity scan analysis (earlier scan) - Richard
949
** 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
950
** Notes on efficiencies in report file:
951
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
952
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
953
*** Tracking efficiency needs to be checked
954
*** 3/4 trigger efficiency seems ok
955
* Discussion luminosity scan analysis (later scan) - Ryan
956
** Fewer carbon runs than earlier scan
957
** Shown is a tracking-based analysis using data from the ROOT trees
958 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
959 35 Stephen Kay
* SIDIS analysis - Hem
960
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
961
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
962
* Analysis of exclusive events in SIDIS - Samip
963
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
964
** Ongoing work on implementing coincidence time into tree
965
* Discussion of run plan, and in particular possible low Q2/low energy
966
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
967
** 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
968
** 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
989
* Discussion of Richard's slides on run plan kinematics and preparations -
990
** 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
991
** 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
