Scintillation Properties of Electromagnetic Calorimeter Modules Based on BaF2 Crystals
We report a study of optical and scintillation properties of modules of a prototype electromagnetic calorimeter based on barium fluoride crystals (BaF2) measuring 25 × 25 × 160 mm3. The length of the crystal radiator of the calorimeter is optimized using the Monte Carlo method in order to improve its energy resolution. Homogeneity of the light output from different sections of the module using gamma quanta from a 137Cs source is demonstrated. The scintillation time of the crystal module under gamma excitation is measured.
