Abstract

Monte Carlo simulation is applied to a detector element for a positron-emission tomograph (PET) prototype based on multipixel silicon photomultipliers and new LFS-3 crystal scintillators to optimize its characteristics such as the light yield and energy resolution. These characteristics were calculated for various configurations of crystal surface treatment and cover material parameters. The highest light yield was achieved for a detector module with a Lumirror reflector as a cover material for the chemically treated scintillation crystal surface. For the above-mentioned configuration, one of the best energy resolution was achieved.
