摘要
一种简单的铝壁比例计数器已经被开发出来，通过照射计数器本身和随后计数(n,p)反应产生的9.8 min Mg27活度产生的β射线来测量低快中子通量。描述了其工作特性，并讨论了其灵敏度。该计数器能够检测快中子通量≈103 n·cm−2·sec−1。
Aluminum proportional counter for the measurement of low fast neutron flux
A simple aluminium-walled proportional counter has been developed to measure low fast neutron flux by irradiation of the counter itself and subsequent counting of the β-rays from the 9.8 min Mg27 activity produced by the (n,p) reaction. The operational characteristics are described and the sensitivity discussed. The counter is capable of detecting a fast neutron flux ≈ 103 n·cm−2·sec−1.
