Abstract
The research results of parameters of LYSO and GSO crystals—candidates for being used in an electronic calorimeter for the COMET experiment—are described. The research has been made at the specially created high precision measuring setup. Measurements of uniformity of LYSO and GSO crystals along the crystal length were made. The energy resolution of crystals, their light output and processing speed were measured. The energy calibration of crystals was also performed. The research results were used for GEANT4 simulation of the calorimeter for COMET experiment. As a result of simulation of the calorimeter on the collimated 105 MeV electrons source with use of real optical parameters, the energy resolution of 5.0% was obtained for a calorimeter on GSO crystals and 2.5% for a calorimeter on LYSO crystals.
