中文摘要：
通过分析康普顿散射成像系统及CdZnTe探测器性能，并考虑到相应核电子学电路的噪声特性，设计了用于康普顿散射成像系统的甄别级CdZnTe探测器，并设计了与探测器相适应的低噪声小尺寸电荷灵敏前置放大器和主放大器。在常温下，5mm×5mm×5mm的甄别级CdZnTe探测器与小尺寸核电子学电路系统对于662keV的^137Cs源，其能量分辨率小于4％。
英文摘要：
The performances of CdZnTe detectors is scatter Imaging system,discriminator grade CdZnTe analysed, and considing of its applying in Compton detector used for Compton Scatter Imaging system is designed, and the nuclear circuit adapting the system is designed also, that is low noised rnicroprearnplifier and main amplifier. At common temperature, the detecting system＇s energy resolution is bellow 4 % to 662 keV ^137Cs γ source with 5 mm× 5 mm× 5 mm discriminator grade CAZnTe detector and micro--nuclear circuits.
