** Lumi SHMS tracking is still showing the trend from 9/8. It was found that the lumi replay script is not updated with many of Ali and Richard's most recent changes. These changes are being applied and a set of new replays will be done.

** Bill's cross-section code is broken into two major parts. The root analysis part, which takes all the yields, uncertainties, etc., is nearly complete with the connecting ltsep framework script finishing up. The second part, where many of the final plots and cross-sections are done, is a hard-coded mess. Richard is in the process of making this more dynamic. This aspect will take more time but the root analysis part is the bulk of the analysis anyways.

** Heep Coin analysis for high Q2 KaonLT data (6.2, 8.2, 10.6 GeV beam energy) has now all the efficiencies/live times applied. The results for all 3 beam energies are looking very good. Data/SIMC ratios are agreeing very well (< 3%) and the shapes are matching up nicely. Next step is to finalize offsets for both low and high Q2 KaonLT data. Also proton absorption correction and target boiling needs to be applied.

** 3.6 and 3.9 GeV data do NOT have the angle offsets. This has been established in the study.

70
** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
71
** 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. 
72
** 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 am trying to expand to lumi singles runs, things get a bit more complex so I am just working out the trigger correlations
328
** Pass 2 runs

*** DEF-files
330
**** I checked out the DEF-files for our combination of the nested files
331
**** There are a lot a files (~150!!!!) and may be hard to track so next week *we should make a flowchart together*

** I have re-run the carbon lumi runs with the changes to the replay events (i.e. All_events_NO_EDTM). The results look pretty good (within a few percent). There are still some trends I need to investigate for certain runs and I need to do the analysis for the pionLT carbon lumi data.

** 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). 
364
** 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.

* SHMS Reference Time Amplitude Cuts(Stephen)
708
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
709
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
710
** This is a temporary fix to "ghost-bands" and cross talk
711
*** Although for HG there is still a small peak. The hodoscope is fine.
712
** The time window is easier to set now.
713
** DC has been fine (since it uses TDC)
714
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
715
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated
716
717 1 Richard Trotta
* Peter's hcana fixes for reference time (Richard)
718 67 Richard Trotta
** Peter implemented changes to hcana
719
** Two major issues...
720 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
721 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
722 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)
723 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
724
** Richard has been checking for bugs in the code. 
725
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
726
727 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
728 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
729 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
730 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

864
** resolving differences between his analysis and Richard's
865
866
* Richard
867
** 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
868
** 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)
908
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
909
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
910
** Efficiency calculation was investigated in detail and applied using scalers from trees
911
** Results for carbon (normalized to 30uA) show large variation - need to understand
912
** *Next steps:*
913
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
914
*** Check stability of pre-scale (Ryan saw changes within runs)
915
*** Check if detector calibrations for runs are implemented correctly
916
*** Analyze with Ryan's cuts
917 1 Richard Trotta
918 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
919
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
920
** Tracking-based analysis for runs 2073-2095
921
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
922
** Included most recent detector calibrations in replay of these runs
923
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
924
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
925
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
926
** *Next steps:*
927 5 Richard Trotta
*** Check tracking efficiency
928 35 Stephen Kay
929
* *Global comments on Luminosity Scans (so far)*
930 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.
931 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
932
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
933
** Uncertainties on current
934
** Detector calibrations
935 1 Richard Trotta
** HMS vs. SHMS
936 35 Stephen Kay
937
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
938
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
939
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
940
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
941
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
942
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
943 1 Richard Trotta
** *Next steps:*
944 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)
945 35 Stephen Kay
946
* Yield normalized ratios from SIDIS (Hem)
947
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
948
** *Next steps:*
949 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
958
** 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
959
** Notes on efficiencies in report file:
960
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
961
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
962
*** Tracking efficiency needs to be checked
963
*** 3/4 trigger efficiency seems ok
964
* Discussion luminosity scan analysis (later scan) - Ryan
965
** Fewer carbon runs than earlier scan
966
** Shown is a tracking-based analysis using data from the ROOT trees
967 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
968 35 Stephen Kay
* SIDIS analysis - Hem
969
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
970
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
971
* Analysis of exclusive events in SIDIS - Samip
972
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
973
** Ongoing work on implementing coincidence time into tree
974
* Discussion of run plan, and in particular possible low Q2/low energy
975
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
976
** 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
977
** Garth will put this together in a draft email
