摘要/Abstract

摘要： 设计了一种前置放大器与探测器分离的中子测量系统,该测量系统将耐辐照性较差的电子学电路与探测器组件分离,通过同轴电缆远距离连接。测试结果显示,该中子测量系统相对固有误差≤8.6%,对Am-Be源与²⁵²Cf源相对响应之差为9%,性能满足设计要求。

Abstract: We have designed a neutron measurement system with the preamplifier separated from the detector. The electronic circuit with poor irradiation resistance from the detector assembly is isolated, and connected remotely through a coaxial cable. The test results show that, the maximum relative inherent error of the probe is only 8.6%, and the difference between the relative response of the Am-Be source and the ²⁵²Cf source is 9%. Its performance meets the design requirements.
