摘　　要：低能(50keV以下)光子探测器广泛应用于外大气层核爆监测,天体物理现象研究。采用半导体探测单元试制了低能X射线探测器模块。说明了配置多探测器系统的方法,并介绍了探测单元模块的设计、主要试验和技术指标。室温下噪声等效输入光子能量为2.1keV。Low energy （less than 50 keV） photon detector is applied extensively to monitoring exoatomsphere nuclear detonation and investigating astrophysical phenomenon.A low energy X-ray detector modular with Si-PD element was developed.The method was explained for scheming multi-detector system.Its design,detector test and technologic characteristics were described.Under room temperature,the noise equivalent input photon energy is 2.1 keV.
