摘要: 根据康普顿散射原理，建立了康普顿散射导致发光玻璃屏模糊的简化模型，并通过数值模拟计算，给出了转换屏厚度对屏空间分辨的影响，数值计算结果与12 MeV 加速器上发光玻璃屏空间分辨率的实验测量值基本吻合。Abstract: A simplified blur model of luminescent glass screen caused by Compton electron scattering is set up based on the Compton scattering theory. The influence of the screen thickness on the screen spatial resolution is given through numerical analysis. Then the screen spatial resolution is experimentally measured by an experiment carried out on 12 MeV linear accelerator, and the result accord with the calculated ones.
