摘要
Cs2LiYCl6 : Ce3+ (CLYC) is a promising new inorganic scintillator for gamma-ray spectroscopy and thermal neutron detection with the capability for pulse-shape discrimination (PSD). We verify the scintillation mechanisms responsible for optical emission under gamma-and neutron-induced excitation by fitting decay functions to the waveform structures. Under gamma-excitation, we observe the ultrafast, fast, intermediate, and slow scintillation mechanisms reported in the literature. Thermal neutron waveforms, however, show no evidence of ultrafast decay. We then investigate the thermal dependence of the waveforms in a range from -20 to +50 degrees C. Despite some thermally-variant emission components, we conclude that PSD is feasible at the range of temperatures investigated.
