Cesium hafnium chloride scintillator coupled with an avalanche photodiode photodetector Open
Optical and scintillation properties of pure Cs2HfCl6 (CHC) single crystals were investigated. In particular, light output and energy resolution were measured using a Si avalanche photodiode (Si-APD), since the Si-APD has sufficient quantu…
