基于硅光电倍增管的Cs2LiYCl6(CLYC)探测器快中子辐照效应研究

Abstract

Abstract: In this experiment, the SiPM device and Cs₂LiYCl₆ (CLYC) scintillator detector were exposed to a 14 MeV fast neutron field, and the maximum cumulative irradiation fluence reached 1.53×10¹¹ cm^-2. The effects of neutron irradiation on the SiPM device parameters and effects on CLYC detector performance were studied. The focus was on the gain, dark count rate, dark current, breakdown voltage, quenching resistance and other parameters of SiPM before and after irradiation with different fluences, as well as the changes and causes for the detection performance of the CLYC detector. Among them, the dark count rate increased the highest with 3 orders of magnitude, the dark current increased by up to 2 orders of magnitude, and the energy resolution of the CLYC detector decreased by 1.4% after removing the background. After the irradiation experiment, the SiPM and CLYC detectors were annealed at room temperature to study the SiPM device parameters and detector performance recovery. The performance of SiPM and CLYC detectors gradually deteriorates as the neutron fluence increases. For SiPM, the main performance is the increase in dark count rate and dark current. For the CLYC detector, the main manifestation is the reduction of energy resolution. The annealing process helps mitigate the effects of neutron irradiation and restores some performance of SiPM and CLYC detectors.
