根据初步模拟和测量,中国锦屏地下实验室 的宇宙线通量约为每年每平方米小于100个宇宙线 的水平.精确的宇宙线通量数据还需要长时间的实 验测量. "According to initial simulations and measurements, the cosmic ray flux of the China Jinping Underground Laboratory (CJPL) is around 100 cosmic rays per year per m2. Accurate cosmic ray influx data still requires measurements from experiments over a long period of time." The diagram in the paper claims that CJPL receives the lowest penetration of cosmic rays of all of the world's underground laboratories of the time.

2010年1月,中国锦屏地下实验室的岩石挖掘工作全部完成。2010年6月,中国锦屏地下实验室的配套工程建设完成,并顺利通过了评审和验收,标 志着我国首个、国际上垂直岩石覆盖最深的极深地下实验室正式建成。2010年7月,中国锦屏地下实验室内第一个暗物质实验项目———中国暗物质实验(China Darkmater [sic] Experiment, CDEX)正式开始了其暗物质实验屏蔽体的建设工作,并于2010年9月完成屏蔽体建设工作。2010年12月12日,中国锦屏地下实验室正式投入使用。CDEX 项目组率先利用中国锦屏地下实验室开始了其基于点接触技术的,极低能量阈高纯锗探测器直接探测暗物质实验 项目的,探测器系统安装和调试。

"In January 2010, the excavation work of CJPL was completed. In June 2010, construction of its supporting projects was complete, and it smoothly went through review and acceptance. It marked the formal completion of the construction of China's first underground laboratory, and the world's most deeply covered by vertical rock. In July 2010, the first dark matter experiment project at CJPL, China Darkmatter Experiment (CDEX), formally began the construction of its dark matter experiment shield, and in completed it in September 2010. On 12th December 2010, CJPL formally began operations. The CDEX group was the first to use CJPL, and began the installation and commissioning of its ultra-low energy threshold, pure germanium probe detector system, which was based on point-contact technology, for the project on the direct probing of dark matter."
