Abstract Energy resolution and the detection efficiency for gamma quanta are fundamental properties in the construction of detectors for ionizing radiation. In this study, a SiPM-based photodetector coupled to a monolithic inorganic CeBr 3 crystal is exposed to gamma rays in order to study the performance of the CeBr 3 crystal. Measurements are made using three different radioactive sources - 137 Cs, 22 Na and 60 Co. For each source, the measurements are made using a few different values for the Bias voltage of the SiPM. Furthermore, two CeBr 3 crystals with different thicknesses are used in order to study how detector efficiency is affected by crystal dimensions. A preliminary analysis of the data is presented.
