Non-proportionality and Photon Interaction Study of CLYC Scintillation Material by Compton Scattering Technique

Abstract

In this research, scintillation properties of Cs 2 LiYCl 6 :Ce (CLYC) scintillation material were studied by Compton scattering technique and the samples were irradiated with eight different photon energies using these technique. Photon interactions have been calculated by WinXCom program at 216-662 keV. The mass attenuation coefficient m )and partial interactions, light yield and non-proportionality were presented. The values of increased toward the decrease of gamma ray energies and are influenced by photon energy and chemical compositions. The partial interactions found that three energy relative to the partial processes first photoelectric absorption, second incoherent (Compton) scattering and third coherent (Rayleigh) scattering.Moreover, the crystal were higher at the low photon energy and decreased with increasing the photon energy. The results of scintillation properties show that slightly increased when increasing the photon energy.The non-proportionality shows demonstrated excellent proportional property in the energy range, the non-proportionality is about 1.5%.
