** 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.
365 71 Richard Trotta
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
366
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
367
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
368
** We can begin looking forward towards efficiencies. 
369
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
370
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways.

*** few runs where HMS cal totally failed (which was dependent on initial parameters)
390
*** Spring looked worse than the rest (surprisingly), but this may be because online calibration wasn't great

398
* Timing update (Stephen)
399
** Reference times between Richard and Stephen are very similar and the GitHub is updated accordingly
400
** Richard is going to add the trigger time cuts once the fall runs are finished (by end of week)
401
** First pass of detector reference time parameter files finished
402 1 Richard Trotta
403 68 Richard Trotta
* Peter's hcana code (Richard and Stephen)
404
** Peter's code does not remove ghost bands (already known), but now Stephen is seeing a strang horizontal band for just SHMS hodoscope 2D plots
405
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
406
** 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.
407
408
* Calibrations were decided to be done once per shift
409
410
* Next meeting schedule...
411 127 Richard Trotta
** Small meetings Nov 12 and Nov 19 (at 3pm EST) so Richard and Stephen can iron out the timing and calibrations
412
** November 26 (at 3pm EST) will be a larger meeting. 
413 68 Richard Trotta
*** This is the rough deadline we made for finishing up calibrations. 
414
*** 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)
423
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
424
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
425
** This is a temporary fix to "ghost-bands" and cross talk
426
*** Although for HG there is still a small peak. The hodoscope is fine.
427
** The time window is easier to set now.
428
** DC has been fine (since it uses TDC)
429
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
430
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated
431
432 1 Richard Trotta
* Peter's hcana fixes for reference time (Richard)
433 67 Richard Trotta
** Peter implemented changes to hcana
434
** Two major issues...
435 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
436 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
437 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)
438 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
439
** Richard has been checking for bugs in the code. 
440
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
441
442 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
443 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
444 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
445 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

579
** resolving differences between his analysis and Richard's
580
581
* Richard
582
** 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
583
** 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)
623
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
624
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
625
** Efficiency calculation was investigated in detail and applied using scalers from trees
626
** Results for carbon (normalized to 30uA) show large variation - need to understand
627
** *Next steps:*
628
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
629
*** Check stability of pre-scale (Ryan saw changes within runs)
630
*** Check if detector calibrations for runs are implemented correctly
631
*** Analyze with Ryan's cuts
632 1 Richard Trotta
633 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
634
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
635
** Tracking-based analysis for runs 2073-2095
636
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
637
** Included most recent detector calibrations in replay of these runs
638
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
639
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
640
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
641
** *Next steps:*
642 5 Richard Trotta
*** Check tracking efficiency
643 35 Stephen Kay
644
* *Global comments on Luminosity Scans (so far)*
645 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.
646 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
647
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
648
** Uncertainties on current
649

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
653
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
654
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
655
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
656
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
657
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
658 1 Richard Trotta
** *Next steps:*
659 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)
660 35 Stephen Kay
661
* Yield normalized ratios from SIDIS (Hem)
662
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
663
** *Next steps:*
664 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
673
** 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
674
** Notes on efficiencies in report file:
675
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
676
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
677
*** Tracking efficiency needs to be checked
678
*** 3/4 trigger efficiency seems ok
679
* Discussion luminosity scan analysis (later scan) - Ryan
680
** Fewer carbon runs than earlier scan
681
** Shown is a tracking-based analysis using data from the ROOT trees
682 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
683 35 Stephen Kay
* SIDIS analysis - Hem
684
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
685
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
686
* Analysis of exclusive events in SIDIS - Samip
687
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
688
** Ongoing work on implementing coincidence time into tree
689
* Discussion of run plan, and in particular possible low Q2/low energy
690
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
691
** 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
692
** Garth will put this together in a draft email
