General Info Tuesdays at 11:00 (JLab time) Room B101 at JLab Bluejeans Confluence Software Runs 2019 Run Spreadsheet FEE Runs: 9371 9371 , 9593, 9898, 9899, 9920, 9921, 10097, 10103, 10104, 10716 , 10717, 10718 ECAL Calibration Tasks Alignment based on survey based on tracking Energy Gains Cosmics (Andrea/Luca, ~Oct 15)relative, before and after the run FEE (Andrea/Luca)dedicated FEE runs, singles triggers Sampling fractionsenergy-dependent, simulation (Andrea) Position/projection correctionspreviously simulation based, no track information Edge corrections (Andrea) based on track-y at ECAL, simulation Time RF (Nathan, ~Oct 15 )signal shape is different relative to 2016 potentially more important for positron/singles triggers than for pairs channel offsets time-walk current parameterization should be fine if convergent or cutoff above 2.2 GeV HODO Calibration Tasks GainsCalculated several time throughout the run, in the database Observed dependence on luminosity, and a tiny bit on time For production runs, a single run from every day (few days) can be used to calculate gains For low-luminosity runs, a single run can be used to calibrate each About 15-20 file will be needed Format? Either hpstr/DST with hodo information should be available, or I have a simple ntuple that gives necessary information TImeCurrently hit time is defined as a threshold crossing time, should we use mode-7 timing algorithm? AlignmentHodo acceptance is covering all the ECal/SVT acceptance Efficiency studies during the run didn't show any efficiency loss close to edges of the calorimeter. Software Tasks Generate aligned detectors (and track scoring plane(s)) survey-based (Nathan) track-based Simulation single-e+ /e- /γ events over entire kinematics for corrections remove 2 dead crystals, e.g. set gains to zero in database Database Final ECAL gains Final HODO gains ECAL Time offsets Add HODO to particle objects Time/position HODO-ECAL coincidence Update ECAL corrections for 2019/4.4 GeV sampling fraction edge shower loss Meeting Agendas/Minutes October 1, 2019 2019/2015 survey analysis Task lists, priorities, assignmentscosmic gains (Andrea/Luca) and RF (Nathan) are first, ~2 weeks followed by FEE gains (Andrea/Luca) and timing offsets then higher order corrections discussed simulation needs for corrections, added to task lists above October 15, 2019 October 29, 2019 RF found signals in data, looks good, extracting to LCIO looks like old pulse fitting method will still work HODO ECAL scoring plane is shifted in v1 detectors, 5 cm upstream of where it should be survey detector ready in software, to PR Simulations Note, EVIO files for all FEE runs (2.4 TB) are pinned on /cache for 30 days as of 10/27 November 26, 2019 ECAL HODO Data Processing / Simulations December 10, 2019 January 14, 2020 February 4, 2020 February 18, 2020 February 25, 2020 Trigger bit EVIO skims going to /cache/hallb/hps/physrun2019/production/evio-skims March 3, 2020 Trigger bit skims done, for all production runs after the SVT was repositoned FEE reconstructed files (no tracking) are here: /cache/hallb/hps/physrun2019/production/pass0.0/fee/ March 17, 2020 March 31, 2020 April 21, 2020 ECAL FEE-based gains are now in the database for the golden run period. June 30, 2020 July 21, 2020 August 4, 2020 August 11, 2020 Andrea's FEE-based gains, after correcting for 2019's higher threshold in MC, are in the database now. the previous state of the database was tagged with physrun2019_ecal_fee_gains_v1 and the current state is tagged as physrun2019_ecal_fee_gains_v2 September 1, 2020 Any looks at data reconstructed with latest gains in database.
