** 3.6 and 3.9 GeV data do NOT have the angle offsets. This has been established in the study.
31 370 Richard Trotta
** I've plotted the offsets vs SHMS central momentum. Plots are attached in the attached pdf file.
32
* Richard
33
** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
34
** 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. 
35
** 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). 
327
** 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.

374 181 Richard Trotta
** He is investigating some of the EDTM rate dependence and sees a discrepancy between the total EDTM LT and CPU LT with a sudden dip at 20-30 kHz. More luminosity runs will need to be studied for a full conclusion.

*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
614
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
615
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
616
** We can begin looking forward towards efficiencies. 
617
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.

671
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
672
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
673
** This is a temporary fix to "ghost-bands" and cross talk
674
*** Although for HG there is still a small peak. The hodoscope is fine.
675
** The time window is easier to set now.
676
** DC has been fine (since it uses TDC)
677
*** 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)
681 67 Richard Trotta
** Peter implemented changes to hcana
682
** Two major issues...
683 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
684 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
685 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)
686 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
687
** Richard has been checking for bugs in the code. 
688
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory

692 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
693 62 Richard Trotta

827
** resolving differences between his analysis and Richard's
828
829
* Richard
830
** 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
831
** 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)
846 111 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
847 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
848

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

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

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