The China Jinping Underground Laboratory (CJPL), located in southwest China's Sichuan Province, is currently under construction for its second phase. The laboratory, which is nestled beneath the Jinping Mountain, aims to unveil the mysteries of the universe through advanced physics experiments. The first phase of the laboratory was completed in 2010 and has achieved significant scientific breakthroughs in dark matter detection. The second phase, called the Deep Underground and Ultra-low Radiation Background Facility, started construction in 2020 and is scheduled to be completed in 2024. It will have a total room capacity of about 330,000 cubic meters and will facilitate research on dark matter, neutrino detection, deep underground medical science, and rock mechanics. The construction of a polyethylene shield cabin, which is a key part of the second phase, has recently been completed. The shield cabin, composed of high-density polyethylene plates, is designed to provide an extremely low radiation background for the laboratory. The CJPL will become a top-tier underground experiment platform with the deepest rock coverage, the lowest cosmic ray flux, and the largest available research space in the fields of particle and nuclear physics, astrophysics, and cosmology.
