** 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 am trying to expand to lumi singles runs, things get a bit more complex so I am just working out the trigger correlations
272
** Pass 2 runs

*** DEF-files

**** There are a lot a files (~150!!!!) and may be hard to track so next week *we should make a flowchart together*

**** Working on my list of branches for the next replay

*** Removed individual PMT info and raw info for many detectors, reduced file size by factor ~2
283
** Updating DEF-files/scripts for calibrations as part of PionLT prep
284
** Will focus on DEF-file/DEF-cut file updates over next week

316
** 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.

*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
739 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)
740 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
741
** Richard has been checking for bugs in the code. 
742
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
743
744 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
745 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
746 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
747 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

*Analysis Updates:*
879
880

881
** resolving differences between his analysis and Richard's
882
883
* Richard
884
** 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
885
** 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.

** Carbon scan from April seems consistent with no boiling, LH3 and LD2 show deviation from unity, should check effect of EDTM events on efficiencies

* Luminosity Scans January 2018 (Richard)
925
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
926
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
927
** Efficiency calculation was investigated in detail and applied using scalers from trees
928
** Results for carbon (normalized to 30uA) show large variation - need to understand
929
** *Next steps:*
930
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
931
*** Check stability of pre-scale (Ryan saw changes within runs)
932
*** Check if detector calibrations for runs are implemented correctly
933
*** Analyze with Ryan's cuts
934 1 Richard Trotta
935 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
936
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
937
** Tracking-based analysis for runs 2073-2095
938
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
939
** Included most recent detector calibrations in replay of these runs
940
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
941
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
942
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
943
** *Next steps:*
944 5 Richard Trotta
*** Check tracking efficiency
945 35 Stephen Kay
946
* *Global comments on Luminosity Scans (so far)*
947 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.
948 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
949
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
950
** Uncertainties on current
951
** Detector calibrations
952 1 Richard Trotta
** HMS vs. SHMS
953 35 Stephen Kay
954
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
955
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
956
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
957
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
958
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
959
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
960 1 Richard Trotta
** *Next steps:*
961 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)
962 35 Stephen Kay
963
* Yield normalized ratios from SIDIS (Hem)
964
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
965
** *Next steps:*
966 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

974 35 Stephen Kay
* Discussion luminosity scan analysis (earlier scan) - Richard
975
** 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
976
** Notes on efficiencies in report file:
977
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
978
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
979
*** Tracking efficiency needs to be checked
980
*** 3/4 trigger efficiency seems ok
981
* Discussion luminosity scan analysis (later scan) - Ryan
982
** Fewer carbon runs than earlier scan
983
** Shown is a tracking-based analysis using data from the ROOT trees
984 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
985 35 Stephen Kay
* SIDIS analysis - Hem
986
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
987
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
988
* Analysis of exclusive events in SIDIS - Samip
989
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
990
** Ongoing work on implementing coincidence time into tree
991
* Discussion of run plan, and in particular possible low Q2/low energy
992
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
993
** 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
994
** 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
1015
* Discussion of Richard's slides on run plan kinematics and preparations -
1016
** 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
1017
** 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
