Abstract

We report on the fabrication and application of a novel neutron imaging test device made of gadolinium. It is designed for a real time evaluation of the spatial resolution, resolution direction, and distortions of a neutron imaging detector system. Measurements of the spatial resolution of (6)LiF doped ZnS scintillator screens with different thicknesses and of imaging plates were performed. The obtained results are in good agreement with comparison measurements using the standard knife edge detection method.

摘要

我们报告了一种由钆制成的新型中子成像测试装置的制造及应用情况。它旨在对中子成像探测器系统的空间分辨率、分辨率方向和畸变进行实时评估。对不同厚度的掺杂(6)LiF的ZnS闪烁体屏以及成像板的空间分辨率进行了测量。所得结果与使用标准刀口检测方法的对比测量结果高度吻合。
