Long term outdoor performance evaluation of stacked coplanar grid (Cd,Zn)Te detectors by spectroscopic environmental radiation monitoring

Abstract

This work focuses on the evaluation of spectroscopic background radiation measurements performed at an outdoor facility on the Schauinsland mountain in Germany. The detector system that was used consisted of two temperature stabilized Coplanar Grid (Cd,Zn)Te detectors together with a custom digital Multi Channel Analyzer. The research presented includes the evaluation of the spectroscopic outdoor performance, the analysis of the correlation of count rates in certain energy regions with meteorological factors and the quantification of the temperature stability.
