Light Yield Non-Proportionality and Energy Resolution of BGO and CsI(Tl) Scintillation Crystals

Abstract

This work was investigated on gamma ray scintillation response of inorganic scintillators. BGO and CsI(Tl) was carried out in the energies ranging from 59 keV to 1332 keV. The scintillation responses of the crystals were measured using photomultiplier tube (R1306 PMT) readout. The light yield non-proportionality and energy resolution were analyzed with Gamma Acquisition & Analysis program. The photofraction for both crystals was determined and compared with the cross-section ratio which calculated by WinXCom program.
