用于ADS次临界反应堆Keff测量微电流放大器的设计

A rapid micro-current amplifier used to measure the Keff of the sub-critical reactor of accelerator driven system

设计了一种基于噪声分析方法,利用反应堆堆芯中子涨落特性测量加速器驱动洁净核能系统(Acceleratordrivensystem,ADS)次临界反应堆动态参数的微电流放大器,并且根据需要设计了微电流源,运用Protel实时电路仿真工具对放大器进行仿真调试,使其达到设计要求。

In this paper a rapid micro-current amplifier used to measure the Keff of the sub-critical reactor of accelerator driven system（ADS） was introduced, which is based on the noise analysis method used in the stochastic neutron and photon transport theory, and a micro-current source was designed. At last the circuit was debugged by the Protel tool and the test result was given.
