Abstract

This comparative study ofthe performances ofCdTe and Cd1.,Zn,Te detectors at temperatures in the 25 -70°C range shows that CdZn2Te has a better performance as a ganimaray detector at elevated temperatures. Peak position shifts as ftinction oftemperature are less pronounced in spectra obtained with CdZn2Te detectors than in spectra from CdTe. The CdZn2Te detectors exhibited a FWHM of 24 % (at 60 °C) at 81 keV without significant deterioration due to the heating cycles.
