摘　　要：通过对次临界反应堆中子噪声特性的分析,设计了一种能反映ADS系统启明星1#实验装置中子涨落特性的微电流放大器。通过设计和调试,该放大器能够实现10^(-9)—10^(-11)A的电流—电压通频带转换放大,达到了设计的要求。Through the analyses the neutron noise character of the sub-critial reactor, a micro-current amplifier was designed that can be used to authentication neutron fluctuations characteristics of the sub-critical experiment facility “Venus 1#” of Accelerator Driven System. At last, 10^-9-10^-11A micro-current can be pass band amplified and conversion to voltage signal.
