(231207) -- JINPING, Dec. 7, 2023 (Xinhua) -- This photo taken on Nov. 7, 2023 shows a piece of waterproof radon-inhibiting layer at the Deep Underground and Ultra-low Radiation Background Facility for Frontier Physics Experiments (DURF) in Liangshan Yi Autonomous Prefecture of southwest China's Sichuan Province. 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. 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

(230715) -- XICHANG, July 15, 2023 (Xinhua) -- A water-and-radon-proof layer is seen on the wall of the C hall of the second phase of China Jinping Underground Laboratory in southwest China's Sichuan Province, July 4, 2023. Jinping Mountain, located in the drainage basin of the Yalong River, the largest tributary of Jinsha River, has the highest altitude of 4,410 meters. The China Jinping Underground Laboratory (CJPL) is located in the middle of the 17.5 kilometer-long Jinping tunnel in southwest China's Sichuan Province. The laboratory, inaugurated in 2010, is an underground research facility with a rock overburden of about 2,400 meters. CJPL-I, the first phase of China Jinping Underground Laboratory (CJPL), has an experimental space of 4000 cubic meters. Since its launch, the China Dark Matter Experiment (CDEX) led by Tsinghua University and the PandaX led by Shanghai Jiaotong University have achieved more than 30 internationally leading dark matter research results. At present, the construction of the De
