** 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.

** Explicit PS calculations
262
*** I have gotten a rough script working for very simple runs (ie low rate, single spectrometer, calibration runs)

*** I am trying to expand to lumi singles runs, things get a bit more complex so I am just working out the trigger correlations
264
** Pass 2 runs
265
*** DEF-files

**** I checked out the DEF-files for our combination of the nested files
267
**** 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
275
** Updating DEF-files/scripts for calibrations as part of PionLT prep
276
** Will focus on DEF-file/DEF-cut file updates over next week

** 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). 
308
** 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.

727 67 Richard Trotta
** Peter implemented changes to hcana

729 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
730 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
731 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)
732 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC

873
** resolving differences between his analysis and Richard's
874
875
* Richard
876
** 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
877
** 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)
917
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
918
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
919
** Efficiency calculation was investigated in detail and applied using scalers from trees
920
** Results for carbon (normalized to 30uA) show large variation - need to understand
921
** *Next steps:*
922
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
923
*** Check stability of pre-scale (Ryan saw changes within runs)
924
*** Check if detector calibrations for runs are implemented correctly
925
*** Analyze with Ryan's cuts
926 1 Richard Trotta
927 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
928
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
929
** Tracking-based analysis for runs 2073-2095
930
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
931
** Included most recent detector calibrations in replay of these runs
932
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
933
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
934
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
935
** *Next steps:*
936 5 Richard Trotta
*** Check tracking efficiency
937 35 Stephen Kay
938
* *Global comments on Luminosity Scans (so far)*
939 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.
940 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
941
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
942
** Uncertainties on current
943
** Detector calibrations
944 1 Richard Trotta
** HMS vs. SHMS
945 35 Stephen Kay
946
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
947
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
948
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
949
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
950
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
951
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
952 1 Richard Trotta
** *Next steps:*
953 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)
954 35 Stephen Kay
955
* Yield normalized ratios from SIDIS (Hem)
956
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
957
** *Next steps:*
958 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

966 35 Stephen Kay
* Discussion luminosity scan analysis (earlier scan) - Richard
967
** 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
968
** Notes on efficiencies in report file:
969
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
970
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
971
*** Tracking efficiency needs to be checked
972
*** 3/4 trigger efficiency seems ok
973
* Discussion luminosity scan analysis (later scan) - Ryan
974
** Fewer carbon runs than earlier scan
975
** Shown is a tracking-based analysis using data from the ROOT trees
976 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
977 35 Stephen Kay
* SIDIS analysis - Hem
978
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
979
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
980
* Analysis of exclusive events in SIDIS - Samip
981
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
982
** Ongoing work on implementing coincidence time into tree
983
* Discussion of run plan, and in particular possible low Q2/low energy
984
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
985
** 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
986
** Garth will put this together in a draft email

1009
** 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
