Interaction of 662 keV Gamma Rays with LYSO(Ce) and BGO Single Crystal Scintillators

Abstract:

The study of photon interactions with matter is very important in many fields such as scientific, industry, medical imaging, biological applications, dosimetry, and radiation shielding for their potential use in radiation physics. Scintillating materials become a main part in detection and spectroscopy of high energy photons. The goal of this work is to study an interaction of 662 keV γ-rays with scintillating materials, namely the LYSO(Ce) and BGO crystals. The light output, energy resolution, intrinsic resolution, and photo-fraction of both crystals with the same size of 5x5x3 mm³ were measured using photomultiplier tube (PMT) readout. The result showed that the light yield of the LYSO(Ce) crystal is much more better than that of the BGO crystal, while its photo-fraction is worse than that of the BGO crystal.
