| Abstract: | Solid-state photomultipliers (SSPMs) is a new type of semiconductor avalanche photodetectors operating in the Geigermode with
negative feedback and allowing detection of individual photons. In recent years, SSPMs are increasingly widely used in nuclear
physics, high-energy physics, medicine, biology, and other fields, replacing vacuum photomultipliers and avalanche photodiodes
(APDs). The negative feedback in SSPMs provides a high multiplication factor (105–106) and an ultralow noise factor (1.01–1.05); however, noises of crosstalk and afterpulsing processes come to the fore in this
case. In this communication, we present the results of experimental measurements of crosstalk processes in various SSPM samples
and analyze the measurement techniques. |
