초록
In this study, gamma radiation detectors are created by integrating the following combinations of different YSO scintillators and PMT(photomultiplier-tubes) respectively: 3mm3mm2mm, 3mm(Dia)15mm, 3mm(Dia)20mm, 10mm(Dia)20mm. In addition, the scintillator with a 10mm diameter was integrated with a light guide with a 2mm thickness, 10mm entry and 3mm exit, using LightTools. The constructed detector used the standard gamma ray sources 137Cs(662keV) to analyze the spectral characteristics of gamma rays. The results indicate that at 662keV, the energy resolutions were 14.46%, 21.10%, and 10.71% for the first three combinations respectively. The best results were recorded for the 10mm(Dia)20mm detector with light guide, which had an energy resolution of 7.48%.
