Abstract:

Inorganic scintillators of CsI(Tl), LYSO and BGO crystals were characterized using photomultiplier tube R1306 PMT readout for gamma ray detection. The photoelectron yield, light yield and photofraction were measured at gamma energies in range 59.5 keV to 1332 keV. It is found that the photoelectron yield of LYSO is much better than that of CsI(Tl) and BGO crystals. CsI(Tl) crystal showed the high light yield of 63855.25 ph/MeV in this energy range, which is better than that of LYSO and BGO crystals. The photofraction for all crystals was determined and compared with the cross-section ratio for the photoelectric effect to the total one which calculated by WinXCom program.
