Monitoring of the calibration constants of the DVCS calorimeter

Abstract : Radiation exposure of the DVCS calorimeter during data taking has degraded the optical properties of the cristals in a time dependent way. This note presents a method which allows to determine the effective gain of each single block all along data taking, relying on the two absolute elastic calibrations performed at the beginning and at the end of the experiment. Consideration of time dependent gain is shown to improve the missing mass resolution, allowing for a better identification of DVCS events.
