| 摘 要： | 宇宙射线斗子成像检测技术具有穿透力强、对高Z材料敏感等特点，特别适合检测特殊核材料，是监控核材料走私的有效方式之一。在搭建μ子成像检测硬件系统的同时，我们开发了一套针对实际硬件系统的模拟系统，并利用该系统开展斗子成像方法的研究。本文将介绍该模拟系统的有关情况，并给出利用该系统得到的仿真结果。相信这一工作将对实际宇宙射线μ子成像系统的设计给出指导意见。

| Abstract: | Cosmic ray muon radiography which has good penetrability and sensitivity to high-Z materials is an effective way for detecting shielded nuclear materials. During the production of muon radiography hard-ware system, we have completed a simulation system based on the real hardware system, and we have be-gun our research in muon radiography algorithms using this simulation system. In this paper, an introduction of this simulation system and present our reconstruction results are given. We believed this work will play a significant role to provide some good insights for the design of a practical muon radiography hard-ware system. |
