Description
Summary:Optical and scintillation properties of pure Cs sub(2) HfCl sub(6)(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 quantum efficiency of around 70 % at emission wavelength region of CHC around 420 nm. This CHC single crystal grown using the vertical Bridgeman method showed light output of 37,000+ or - 2,000 photons/MeV . The FWHM energy resolution was determined to be 3.7+ or - 0.5x (E/662 keV) super(-0.85+ or - 0.03)[%], where E[keV] is the gamma-ray energy. Moreover, the temperature dependence of the light output was stable from -5 to 30 super(o) C, while the light output increased below -10 super(o) C.
