Runs
- 2019 Run Spreadsheet
- FEE Runs: 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 fractions
- energy-dependent, simulation (Andrea)
- Position/projection corrections
- previously simulation based, no track information
- Edge corrections (Andrea)
- based on track-y at ECAL, simulation
- Time
- RF (Nathan)
- channel offsets
- time-walk
- current parameterization should be fine if convergent or cutoff above 2.2 GeV
HODO Calibration Tasks
- Gains
- Calculated 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
- TIme
- Currently hit time is defined as a threshold crossing time, should we use mode-7 timing algorithm?
- Alignment
- Hodo 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, assignments
- cosmic 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

- 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/

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
