Abstract

We report an investigation of optical and scintillation characteristics of a prototype module of an electromagnetic calorimeter based on a Lu2SiO5‒z:Y3+:Ce3+:Ca2+ crystal with the size of 20 × 20 × 90 mm3 and grown by the Czochralski method. The scintillation decay time of the crystal module excited by gamma quanta by a 137Cs source is obtained. The energy resolution of the crystal module is estimated by simulating it with the GEANT4 program.
