摘要

对不同能量（2 0— 10 0keV）的X射线在充 3个大气压Xe的多丝室中与Xe原子相互作用的过程进行了蒙特卡罗模拟研究

讨论康普顿散射和Xe的特征X射线对高气压丝室的定位性能的影响

并通过对低密度试模成像的模拟

观察KX射线在高气压丝室中引起的图象畸变。同时提出了一种对特征KX射线和散射射线引起的图象畸变的修正方法

Abstract

The multi- wire proportional counter (MWPC) has been intensively applied to the image formation measurement in high energy physics. The interaction of various energy X-rays (20—100keV) with Xe atoms in a MWPC filled with high pressure Xe gas was studied by Monte Carlo simulation. The influence of scattered X-ray and Xenon’s KX-ray on the accuracy of position determination with the counter was investigated. The distortion of image coused by scattered and KX-rays was studied by low density virtual model simulation. A method was proposed to correct the image distortion.
