According to comprehensive reports from CCTV News and Xinhua News Agency, just today, the Jinping large facility located 2,400 meters underground in Jinping Mountain in Liangshan Yi Autonomous Prefecture, Sichuan Province was officially put into scientific operation. According to reports, on December 7, the civil engineering and public works of China’s Jinping Underground Laboratory Phase II Extremely Deep Underground Ultra-Low Radiation Background Frontier Physics Experiment Facility (referred to as “Jinping Large Facility”) were completed and experimental conditions were met, which marked theThe world's deepest and largest ultra-deep underground laboratory is officially put into scientific operation.
It is reported that the Jinping facility is located 2,400 meters underground in Jinping Mountain, Liangshan Yi Autonomous Prefecture, Sichuan Province.It is equivalent to a height of 800 floors and has a total volume of 330,000 cubic meters..
Because it is deep underground, the laboratory's cosmic ray flux is only one hundred millionth of that on the surface. The experimental environment is the purest in the world, and it has many advantages such as "extremely low environmental radon emission", "extremely low environmental radiation", "ultra-low cosmic ray flux" and "ultra-clean space".
It can provide experimental conditions for dark matter research, neutrino measurements, and nuclear astrophysics, and will be developed to coverParticle physics, nuclear astrophysics, cosmology, life sciences, rock mechanicsand other multi-disciplinary world-class deep earth science research centers.
Currently, the first batch of 10 experimental project teams from universities and research institutes such as Tsinghua University, Shanghai Jiao Tong University, Beijing Normal University, China Institute of Atomic Energy, and Wuhan Institute of Rock and Soil Mechanics of the Chinese Academy of Sciences have stationed to carry out scientific experiments.
