Description

对物体内部结构和成份进行无损探测和成像,是认识物质世界的最直接手段之一。当前,X射线、电子、质子、中子等辐射成像技术已经应用到生产、生活以及科学研究的方方面面。然而,由于人造射线穿透力和覆盖面积有限,在特殊核材料检测和大尺度物体成像方面,仍存在很大的局限性。除了上述人造射线外,在地球表面,还有一种无处不在的射线——宇宙线缪子,其具有穿透强、覆盖范围大、无辐射危害等优点,能解决上述应用所面临的困难。 目前,宇宙线缪子成像技术发展尚未成熟,有大量的难点与挑战亟待攻克。本研究利用Micromegas探测器开展高分辨缪子成像系统研究,旨在研制一套高分辨、多用途的缪子成像装置(μSTC——μ Scattering and Transmission imaging faCility)。本套装置利用热熔胶工压接工艺实现的大面积、高位置分辨Micromegas探测器作为径迹测量模块,使用位置编码压缩方法和高集成度、可扩展读出电子学系统进行读出。根据不同用途,该成像装置可配置为散射成像和透射成像两种模式。基于散射成像模式,目前已开展物质成像和区分实验,可以在数小时内实现2cm尺寸的物质成像。基于透射成像模式,对中国科学技术大学教学科研楼展开了测试,可以在数天实现建筑物成像。 本研究将继续开展大面积、高分辨成像系统研制,并展开中小型重核材料成像和火山、大型人工建筑成像。
