Description

technical field [0001] The present application relates to the field of radiation detectors, in particular to digital SiPM array detectors. Background technique [0002] In the past, scintillation crystals were usually coupled with photomultiplier tubes (PMTs) to develop radiation detectors. However, due to the large size of PMTs, high operating voltage (1000-1500V), and sensitivity to electromagnetic fields, a new type of detector is urgently needed in some application fields. to replace PMT-based scintillator detectors. Silicon photomultiplier (SiPM) is replacing PMT in many application directions due to its small size, low operating voltage, insensitivity to magnetic field, and low cost. It is gradually becoming the photoelectric conversion device of choice for scintillation crystal detectors. Array detectors have also become a hot spot for relevant researchers in recent years. Contents of the invention [0003] The purpose of this application is to provide a digital S...
