Simulation and research of the gamma-ray detectors based on the CsI crystals and Silicon Photomultipliers

摘要

The paper discusses the problems of development of the SiPM-based gamma-detectors. The main focus is on the most effective coupling between the scintillation crystal and the SiPM. We have used a simple optical model to study the different schemes of the coupling and analyze these variants from the point of view of efficiency and uniformity of the signal on the SiPM areas. We present the process and the results of the modeling.
