COSINE是一个暗物质搜索实验，基于位于阳阳地下实验室的低背景NaI（Tl）晶体阵列。COSINE-100的组装于2016年夏天完成，目前正在收集物理质量数据，旨在重现DAMA/LIBRA实验，该实验报告了年度调制信号。已实现稳定运行，并将持续至少2年。在这里，我们描述了COSINE-100的设计，包括屏蔽安排，配置的NaI（Tl）晶体检测元件，否决系统，以及相关的操作系统，我们显示了目前的实验性能。
COSINE is a dark matter search experiment based on an array of lowbackground NaI(Tl) crystals located at the Yangyang underground laboratory. The assembly of COSINE-100 was completed in the summer of 2016 and the detector is currently collecting physics quality data aimed at reproducing the DAMA/LIBRA experiment that reported an annual modulation signal. Stable operation has been achieved and will continue for at least 2 years. Here, we describe the design of COSINE-100, including the shielding arrangement, the configuration of the NaI(Tl) crystal detection elements, the veto systems, and the associated operational systems, and we show the current performance of the experiment.
