Abstract :
The Freiburg Materials Research Center (FMF) is developing a spectroscopic system with high efficiency and high energy resolution based on (Cd,Zn)Te detectors with coplanar grid (CPG) configuration. Our system features an improved multi-channel analyzer with digital signal processing and a large volume detector stack. Thermoelectric cooling is used to improve energy resolution and maintain detector temperature at a constant value. System performance under laboratory and outdoor conditions is investigated in this paper.
