摘要：
ICARUS-T600液氩时间投影室在费米实验室的浅埋深度运行，因此暴露于高通量宇宙线中，这些宇宙线可能伪造中微子相互作用。为减轻宇宙线诱发的本底，研究人员开发了一套宇宙线标记（CRT）系统（约1100平方米），该系统采用两层内嵌光纤的塑料闪烁体环绕低温恒温器。利用纳秒级时间信息，CRT能够区分入射宇宙线与TPC内中微子相互作用产生的出射粒子。本文讨论了CRT系统的概况、其在费米实验室的安装与调试，以及其性能。
英文摘要：
The ICARUS-T600 Liquid Argon Time Projection Chamber is operating at Fermilab at shallow depth and thus exposed to a high flux of cosmic rays that can fake neutrino interactions. A cosmic ray tagging (CRT) system ($\sim$1100 m$^2$), surrounding the cryostat with two layers of fiber embedded plastic scintillators, was developed to mitigate the cosmic ray induced background. Using nanosecond-level timing information, the CRT can distinguish incoming cosmic rays from outgoing particles from neutrino interactions in the TPC. In this paper an overview of the CRT system, its installation and commissioning at Fermilab, and its performance are discussed.
