Abstract

A neutron scintillation detector based on a position-sensitive photomultiplier has been developed for neutron spin echo and small angle neutron scattering measurements. This photomultiplier has good spatial resolution, less than 1 mm2. The detection efficiency of gamma ray background is very low for using a thin ZnS/6LiF scintillator. The effective area of this detector is around 60 cm2.

摘要

一种基于位置灵敏光电倍增管的中子闪烁探测器已被开发出来，用于中子自旋回波和小角中子散射测量。这种光电倍增管具有良好的空间分辨率，小于1平方毫米。使用薄的ZnS/6LiF闪烁体时，伽马射线本底的探测效率非常低。该探测器的有效面积约为60平方厘米。
