COSINE-100暗物质搜索实验已经开始获取物理数据，目标是对DAMA/LIBRA观测到的年度调制信号进行独立测量。在COSINE-100探测器周围屏蔽层的最外层使用塑料闪烁体面板，构建了μ子探测器。它探测宇宙射线μ子，以了解μ子年度调制对暗物质分析的影响。每个模块的组装和初始性能测试已在地面实验室进行。2016年夏天，探测器在阳阳地下实验室（Y2 L）的安装完成。使用三个月的数据，μ子地下通量测量为328 +/- 1（统计）。+/- 10（系统）μ介子/m（2）/天。在这份报告中，组装的μ子探测器和分析的结果。
The COSINE-100 dark matter search experiment has started taking physics data with the goal of performing an independent measurement of the annual modulation signal observed by DAMA/LIBRA. A muon detector was constructed by using plastic scintillator panels in the outermost layer of the shield surrounding the COSINE-100 detector. It detects cosmic ray muons in order to understand the impact of the muon annual modulation on dark matter analysis. Assembly and initial performance tests of each module have been performed at a ground laboratory. The installation of the detector in the Yangyang Underground Laboratory (Y2L) was completed in the summer of 2016. Using three months of data, the muon underground flux was measured to be 328 +/- 1( stat.) +/- 10( syst.) muons/m(2)/day. In this report, the assembly of the muon detector and the results from the analysis are presented.
