本文介绍了一种位置灵敏~ 3 He热中子正比计数器，它采用了一种新颖的信号读出方法，即在计数器体的一端有两个前置放大器。它具有在特殊环境中使用的优势，例如在亚临界设施或水中，或插入狭窄空间。用热中子评价了计数器的特性。位置分辨率为7 mm，有效长度为1,200 mm，位置信号的积分非线性小于0.5%。
A position sensitive 3He proportional counter for thermal neutrons with a novel signal read- out method which has two pre-amplifiers at only one end of the counter body has been developed. It has an advantage for usage in a special environment, such as in a subcritical facility or in water, or for insertion into a narrow space. The characteristics of the counter were evaluated with thermal neutrons. The position resolution was 7 mm with an effective length of 1,200 mm. The integral non-linearity of position signal was less than 0.5%.
