Initial ECAL gain calibration using Compton scattering events

  • run at small small photon flux; use low-energy TAGH counters to constrain the total energy
  • Run conditions:
- amorphous radiator 10-4 R.L., 100 nA beam current
- ECAL & FCAL ( & BCAL trigger), small energy threshold on the total energy (TBD)
- run duration (TBD)

Initial ECAL gain calibration using Compton scattering events

Adjust HV, take more Compton scattering data

- several data sets will be needed to properly adjust HVs
