A 2,400-meter-deep physics laboratory in southwest China’s Sichuan Province became operational on Thursday, making it the deepest and largest underground lab in the world, Report informs via AZERTAC.
Scientists believe the laboratory provides a “clean” space for them to pursue the invisible substance known as dark matter. They said the extreme depth helps block most cosmic rays that mess with the observation.
The Deep Underground and Ultra-low Radiation Background Facility for Frontier Physics Experiments (DURF) is located beneath Jinping Mountain in Sichuan’s Liangshan Yi Autonomous Prefecture.
The DURF, with a total room capacity of 330,000 cubic meters, is the second phase of China Jinping Underground Laboratory. It started construction in December 2020 and was jointly built by Tsinghua University and Yalong River Hydropower Development Company, Ltd.
