Gamma-ray spectrometry using scintillation detectors is one of the most important measurement techniques employed in various fields of nuclear physics and related research. This method finds applications in fundamental nuclear physics studies, environmental monitoring, nuclear medicine, and modern border security systems.Scintillation detectors consist of a scintillating material, which absorbs gamma quanta and subsequently emits light, and a photodetector responsible for registering this signal. The most commonly used photodetectors include PIN diodes, avalanche photodiodes (APDs), vacuum photomultiplier tubes (PMTs), and modern silicon photomultipliers (SiPMs).This presentation will cover the operating principles of silicon photomultipliers, their advantages and limitations, as well as their potential applications in detecting light emitted by scintillators in gamma-ray spectrometry and neutron detection. Special emphasis will be placed on their use in physics, medicine, and security systems.
