Abstract :
A few kinds of CdZnTe detectors are analysed in this paper. Considering of the property of CBS system, the electrode structure of discriminator grade CdZnTe detector and the associated low noised micro-preamplifier and shaping amplifier used for CBS system are designed. At room temperature, the detecting system´s energy resolution with 5 mm times 5 mm times 5 mm discriminator grade CdZnTe detector and micro-nuclear electronics circuits is 3.87%(FWHM) for 662 keV 137Cs gamma-ray source.
