** 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). 
75
** Some PionLT carbon runs were looked at but there are still some issues (either cut or pathing related).

** Luminosity studies
85
*** PionLT carbon runs
86
**** Still having issues getting decent results. I think I am just missing a definition somewhere that I need to track down
87
*** Uncertainties
88
**** Easy to do, I just need to put it into my script
89
** Explicit PS calculations
90
*** I have gotten a rough script working for very simple runs (ie low rate, single spectrometer, calibration runs)
91
*** I am trying to expand to lumi singles runs, things get a bit more complex so I am just working out the trigger correlations
92
** Pass 2 runs
93
*** DEF-files
94
**** I checked out the DEF-files for our combination of the nested files
95
**** There are a lot a files (~150!!!!) and may be hard to track so next week *we should make a flowchart together*
96
**** Working on my list of branches for the next replay
97
***** Mainly just working on my list of branches for the explicit PS calculations
98
***** *Everyone should have a list of these branches by next mini-meeting (4/7/21)*

** Updated DEF-File for the "full" replay
101
*** Can't remove NData brances, Mark says they won't take up too many resources anyway
102
*** Removed individual PMT info and raw info for many detectors, reduced file size by factor ~2
103
** Updating DEF-files/scripts for calibrations as part of PionLT prep
104
** Will focus on DEF-file/DEF-cut file updates over next week
105
*** 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). 
136
** 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.

504 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.
505 71 Richard Trotta
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
506
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
507
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
508
** We can begin looking forward towards efficiencies. 
509
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
510
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways. 
511
512
* Hem
513
** Has been looking at the calorimeter as well. 
514 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.

* Peter's hcana code (Richard and Stephen)
544

545
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
546
** 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.

553 68 Richard Trotta
*** This is the rough deadline we made for finishing up calibrations. 
554
*** This should be sufficient for all detectors (although hodoscope and HG which may persist). The ultimate goal is for all calibrations to be finished up before Winter break!!

* SHMS Reference Time Amplitude Cuts(Stephen)
563
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
564
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
565
** This is a temporary fix to "ghost-bands" and cross talk
566
*** Although for HG there is still a small peak. The hodoscope is fine.
567
** The time window is easier to set now.
568
** DC has been fine (since it uses TDC)
569
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
570
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated
571
572 1 Richard Trotta
* Peter's hcana fixes for reference time (Richard)
573 67 Richard Trotta
** Peter implemented changes to hcana
574
** Two major issues...
575 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
576 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
577 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)
578 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
579
** Richard has been checking for bugs in the code. 
580
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
581
582 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
583 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
584 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
585 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

722
** 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
723
** 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)
763
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
764
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
765
** Efficiency calculation was investigated in detail and applied using scalers from trees
766
** Results for carbon (normalized to 30uA) show large variation - need to understand
767
** *Next steps:*
768
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
769
*** Check stability of pre-scale (Ryan saw changes within runs)
770
*** Check if detector calibrations for runs are implemented correctly
771
*** Analyze with Ryan's cuts
772 1 Richard Trotta
773 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
774
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
775
** Tracking-based analysis for runs 2073-2095
776
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
777
** Included most recent detector calibrations in replay of these runs
778
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
779
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
780
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
781
** *Next steps:*
782 5 Richard Trotta
*** Check tracking efficiency
783 35 Stephen Kay
784
* *Global comments on Luminosity Scans (so far)*
785 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.
786 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
787
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
788
** Uncertainties on current
789
** Detector calibrations
790 1 Richard Trotta
** HMS vs. SHMS
791 35 Stephen Kay
792
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
793
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
794
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
795
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
796
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
797
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
798 1 Richard Trotta
** *Next steps:*
799 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)
800 35 Stephen Kay
801
* Yield normalized ratios from SIDIS (Hem)
802
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
803
** *Next steps:*
804 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
813
** 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
814
** Notes on efficiencies in report file:
815
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
816
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
817
*** Tracking efficiency needs to be checked
818
*** 3/4 trigger efficiency seems ok
819
* Discussion luminosity scan analysis (later scan) - Ryan
820
** Fewer carbon runs than earlier scan
821
** Shown is a tracking-based analysis using data from the ROOT trees
822 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
823 35 Stephen Kay
* SIDIS analysis - Hem
824
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
825
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
826
* Analysis of exclusive events in SIDIS - Samip
827
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
828
** Ongoing work on implementing coincidence time into tree
829
* Discussion of run plan, and in particular possible low Q2/low energy
830
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
831
** 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
832
** Garth will put this together in a draft email

850 18 Richard Trotta
851 35 Stephen Kay
*  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.
852
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
853
* Discussion of Richard's slides on run plan kinematics and preparations -
854
** 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
855
** 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
856
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
857
** kinematics plots W-Q2 show that still need to do some optimization
858
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
859
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
860 26 Richard Trotta
861 35 Stephen Kay
* *Action Items:*
