Abstract
Gd/sub 2/SiO/sub 5/(Ce/sup 3+/) (GSO) and BaF/sub 2/ electron responses were characterized using the Compton Coincidence Technique (CCT). The CCT has been used previously to characterize several scintillators and has proven to be an accurate and reliable technique. The GSO measured electron response was observed to increase by 28% as the electron energy increased from 5 keV to 445 keV. BaF/sub 2/ measured electron response increased by 22% as the electron energy increased from 18 keV to 436 keV. The observations made with GSO and BaF/sub 2/ in this study are consistent with the general trend reported for previously characterized non-alkali halide scintillators. The GSO and BaF/sub 2/ measured electron responses were further used to calculate their respective photon responses. MCNP4C together with simplified electron cascade sequences for GSO and BaF/sub 2/ were used in these photon responses calculations. Calculated photon responses for both crystals are in good agreement with measured photon responses. This agreement confirms the accuracy of the GSO and BaF/sub 2/ measured electron responses.
