摘　　要：介绍了碲锌镉探测器对低能X射线的探测,并在不同温度下测试了其性能变化,包括电子学噪声,能量分辨率和漏电流的变化。同时研制了低噪、性能稳定的厚膜电路用于单路信号的读出,对241Am的60keV能量峰的能量分辨率达到了4%。The paper introduces the detection of CZT detectors to low energy photos. The performance variation of CZT detectors under different temperatures are measured including electronic noise, energy resolution and leakage current. At the same time we developed the low noise and performance stable thick film hybrid circuit which could be applied to single signal read out and portable spectroscopes. The energy resolution for 241Am is around 4 %.
