*** Shapes of SIMC and data are very off
34
*** It seems to be a systematic issue on Vijay's part because the same issue is being seen in PLT data
35 231 Vijay Kumar
*** The main issue in my input file was the target thickness, which picked up by Dave in the group meeting. I corrected the target thickness and now it looks ok. See the attached pdf file below.

** 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.

** Updated Lumi carbon plots with uncertainties. PID and current cuts need to be played around with a bit to see if they improve things (as uncertainties don't explain any boiling-type behaviors). 
90
** Some PionLT carbon runs were looked at but there are still some issues (either cut or pathing related).

*** Uncertainties
103
**** Easy to do, I just need to put it into my script
104
** Explicit PS calculations
105
*** I have gotten a rough script working for very simple runs (ie low rate, single spectrometer, calibration runs)
106
*** I am trying to expand to lumi singles runs, things get a bit more complex so I am just working out the trigger correlations
107
** Pass 2 runs
108
*** DEF-files
109
**** I checked out the DEF-files for our combination of the nested files
110
**** There are a lot a files (~150!!!!) and may be hard to track so next week *we should make a flowchart together*
111
**** Working on my list of branches for the next replay
112
***** Mainly just working on my list of branches for the explicit PS calculations

115
** Updated DEF-File for the "full" replay
116
*** Can't remove NData brances, Mark says they won't take up too many resources anyway
117
*** Removed individual PMT info and raw info for many detectors, reduced file size by factor ~2
118
** Updating DEF-files/scripts for calibrations as part of PionLT prep
119
** Will focus on DEF-file/DEF-cut file updates over next week
120
*** Will investigate HeeP replays over rest of this week.

** 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). 
151
** 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.

519 1 Richard Trotta
** The calibrations are nearing completion with only the HG Cherenkov and SHMS calorimeter yet to be finished. There are also smaller issues with some DC and HMS calorimeter runs.
520 71 Richard Trotta
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
521
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
522
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
523
** We can begin looking forward towards efficiencies. 
524
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
525
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways. 
526
527
* Hem
528
** Has been looking at the calorimeter as well. 
529 70 Richard Trotta
** He has seen the second band in the spectra for some runs, we suggested further looks into HMS hodoscope and subsequently reference times. A recalibration will need to be performed.

560
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
561
** This means we still need the reference time amplitude cut with Peter's code but using just the amplitude cut with Mark's latest version of hcana should be sufficient for calibrations.

* SHMS Reference Time Amplitude Cuts(Stephen)
578
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
579
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
580
** This is a temporary fix to "ghost-bands" and cross talk
581
*** Although for HG there is still a small peak. The hodoscope is fine.
582
** The time window is easier to set now.
583
** DC has been fine (since it uses TDC)
584
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
585
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated
586
587 1 Richard Trotta
* Peter's hcana fixes for reference time (Richard)
588 67 Richard Trotta
** Peter implemented changes to hcana
589
** Two major issues...
590 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
591 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
592 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)
593 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
594
** Richard has been checking for bugs in the code. 
595
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
596
597 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
598 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
599 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
600 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

732
733
* Ryan 
734
** resolving differences between his analysis and Richard's
735
736
* Richard
737
** 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
738
** 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.

** Optimal range is between electron angles of 17-20 degrees, time required ranges from ~1 hour at 17 degrees to ~3 hour at 20 degrees, other angles may be of interest for disentangling charge and current dependent effects

* Luminosity Scans January 2018 (Richard)
778
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
779
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
780
** Efficiency calculation was investigated in detail and applied using scalers from trees
781
** Results for carbon (normalized to 30uA) show large variation - need to understand
782
** *Next steps:*
783
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
784
*** Check stability of pre-scale (Ryan saw changes within runs)
785
*** Check if detector calibrations for runs are implemented correctly
786
*** Analyze with Ryan's cuts
787 1 Richard Trotta
788 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
789
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
790
** Tracking-based analysis for runs 2073-2095
791
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
792
** Included most recent detector calibrations in replay of these runs
793
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
794
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
795
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
796
** *Next steps:*
797 5 Richard Trotta
*** Check tracking efficiency
798 35 Stephen Kay
799
* *Global comments on Luminosity Scans (so far)*
800 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.
801 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
802
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
803
** Uncertainties on current
804
** Detector calibrations
805 1 Richard Trotta
** HMS vs. SHMS
806 35 Stephen Kay
807
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
808
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
809
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
810
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
811
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
812
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
813 1 Richard Trotta
** *Next steps:*
814 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)
815 35 Stephen Kay
816
* Yield normalized ratios from SIDIS (Hem)
817
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
818
** *Next steps:*
819 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
828
** 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
829
** Notes on efficiencies in report file:
830
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
831
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
832
*** Tracking efficiency needs to be checked
833
*** 3/4 trigger efficiency seems ok
834
* Discussion luminosity scan analysis (later scan) - Ryan
835
** Fewer carbon runs than earlier scan
836
** Shown is a tracking-based analysis using data from the ROOT trees
837 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
838 35 Stephen Kay
* SIDIS analysis - Hem
839
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
840
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
841
* Analysis of exclusive events in SIDIS - Samip
842
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
843
** Ongoing work on implementing coincidence time into tree
844
* Discussion of run plan, and in particular possible low Q2/low energy
845
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
846
** 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
847
** 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.
867
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
868
* Discussion of Richard's slides on run plan kinematics and preparations -
869
** 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
870
** 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
871
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
872
** kinematics plots W-Q2 show that still need to do some optimization
873
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
874
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
