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
WABs
Sampling fractions
energy-dependent, simulation
Position/projection corrections
previously simulation based, no track information
Edge corrections
based on track-y at ECAL, simulation
Time
RF (Nathan, ~Oct 15)
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
+

-
/γ events over entire kinematics for corrections
remove 2 dead crystals, e.g. set gains to zero in database
Validating RF extraction
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

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

ECAL
Energy calibration
First look at cosmics:

RF calibration
Surveys
before
and
after
the 2019 run
agree?
HODO
Simulations
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
fee, mult2, mult3 bits
March 3, 2020
Trigger bit skims done, for all production runs after the SVT was repositoned
FEE reconstructed files (no tracking) are here:
