Efficiency stability of HPGe detectors under distinct count rates

Brazilian Journal of Radiation Sciences, 2021
In this work the reproducibility of the efficiency of different HPGe detectors was analyzed under a series of different conditions. The detectors studied were plugged either to a regular analogical amplifier or to a digital signal processing (DSP) device,
