摘要
中子束的准直比、镉比、散射中子及注量率空间分布等是影响中子射线照相性能的主要因素,本文通过蒙特卡罗模拟仿真计算来分析各因素对中子照相图像质量的影响,并提出相应的应对措施。
The main influence factors of thermal neutron radiography include collimation ratio, cadmium ratio, scattering neutron, spatial distribution of neutron flux and so on. In this paper, the influence factors on thermal neutron imaging quality are analyzed by Monte Carlo simulation, and relevant measures are proposed for quality improvement of the thermal neutron imaging technique.
