Description
A compact scintillation detector system based on SiPM and GAGG:Ce crystals has been developed to provide a small $\gamma$-spectroscopy system for the deployment in pipe-work with suspected nuclear contamination. The sensor also shows very good performance in the detection of $\beta$-particles.
An energy resolution of 7% for $E_\gamma=662 keV$ has been achieved with a peak-to-total ratio of 34% at this energy.
The radiation hardness of the material was studied for the first time by examining the photo-luminescence spectrum for a variety of doses up to 100 kGy, delivered by a calibrated $^{60}Co$-source. A deterioration of 15% has been found.
The presentation will detail the design, tests and performance of the system and compare this to the requirements of nuclear and environmental science.
