摘要
介绍了涂硼正比计数管工作原理,分析了电磁干扰、接地干扰和环境温度变化对涂硼正比计数管中子探测的不利影响;开展了一种抗干扰涂硼正比计数管研制,探讨了其结构、关键工艺和主要参数;实验测试结果表明,探测器抗干扰能力强,可用于核电站堆外核测量系统源量程中子注量率测量,以及四代堆型等高温场合下中子注量率监测。
The basic principles of boron-lined proportional counter are introduced in this paper.Interference sources such as electromagnetic interference,grounding interference,temperature change are analyzed.Development of an anti-interference boron-lined proportional counter,and design of structural,key processes,main parameters are described.The experimental results show that strong anti-interference ability of detector,and can be used to measure the neutron fluence rate of reactor ex-core nuclear instrument system,and neutron fluence rate under elevated temperatures conditions such as the generation IV nuclear energy systems.
