Paper Abstract

This comparative study of the performances of CdTe and Cd1--x)ZnxTe detectors at temperatures in the 25 - 70 degree(s)C range shows that Cd0.8Zn0.2Te has a better performance as a gamma-ray detector at elevated temperatures. Peak position shifts as function of temperature are less pronounced in spectra obtained with Cd0.8Zn0.2Te detectors than in spectra from CdTe. The Cd0.8Zn0.2Te detectors exhibited a FWHM of 24% (at 60 degree(s)C) at 81 keV without significant deterioration due to the heating cycles.
