Abstract
In this study, the scintillation performance of Ce doped Cs2LiYCl6 (CLYC) from −30°C to 180°C is presented. Pulse shape discrimination (PSD) of CLYC at various temperatures is investigated. Previously, it had been shown that PSD based on Core-Valence-Luminescence fades away at temperatures >120°C. However, it has been discovered that there is a secondary mechanism which can be utilized for neutron-gamma Pulse Shape Discrimination in addition to the well-known Core-Valence-Luminescence (CVL). In contrast to CVL, this mechanism is found to be insensitive to temperature change. Temperature dependent PSD algorithms are developed to enable reliable neutron-gamma PSD up to 180°C.
