Energy Calibration w/MIP
First energy scale is calibrated by cosmic muon. 38MeV during construction
Measured MIP energy in W0/W1 sectors.
- June-July
- W0: 266.1?1.3MeV
- W1: 276.7?1.2MeV
- Aug
- W0: 266.3?0.03MeV
- W1: 257.1?0.02MeV
Gain shift during between June/July and Aug.
- W0: 0.1?0.4%
- W1: -7.0?0.4%
Laser monitoring will be used soon in the analysis.
