Abstract

Characteristics of a gamma-ray detector that utilizes a 24×24×15-mm3 bismuth germanate (BGO) scintillator are measured. Fluorescent light output measured with a BGO crystal coupled to a R1306 photomultiplier (Hamamatsu TV) is found to be 15% that of a NaI(T1) scintillator for incident photons of a given energy. The FWHM of the time spectrum, measured with two BGO crystals coupled to R329-2 photomultipliers, is equal to 2.0 ns for a 68Ge–68Ga source at room temperature.
