China Jinping Underground Laboratory, also known as the Extremely Deep Underground Very Low Radiation Background Frontier Physics Experiment Facility, referred to as Jinping Facility (CJPL), is located in the middle of the Jinping Mountain Tunnel of Jinping Hydropower Station in Liangshan Prefecture, Sichuan, and was built in 2009In this article, I will lead you to uncover its identity and importance, and let us step into this mysterious underground laboratory to explore its mysteries.
Overview of Jinping facilities
It is jointly built and operated by SDIC Yalong River Hydropower and Tsinghua University, and mainly carries out cutting-edge basic scientific research such as dark matter, neutrinos, nuclear astrophysics, and deep earth medicine.
The Jinping Facility uses Jinping Mountain as a natural barrier and is based on the deep buried long tunnel of Jinping II Hydropower Station running through Jinping Mountain. With an average buried depth of more than 2,400 meters and a total volume of more than 330,000 cubic meters, the laboratory is currently the deepest and largest underground laboratory in the world. Compared with other underground laboratories in the world, China Jinping Underground Laboratory has the deepest rock coverage, the smallest cosmic ray flux, the largest available space, and has the advantages of convenient transportation, sufficient power and water sources, and complete infrastructure.
Research direction of laboratory projects
The Jinping Facility Project is oriented to the major basic frontier research of new particles and new physics that surpasses the current standard model of particle physics, and carries out direct detection experiments of dark matter, neutrino-free double-beta decay experiments, as well as key nuclide synthesis processes and stellar evolution in the field of nuclear astrophysics. New technology, the development of new methods and technologies of extremely low radiation background shielding, to provide platform support for the research of major basic frontier physics problems in the field of particle physics and nuclear physics in China.
China Jinping Underground Laboratory has the world's advanced ultra-low radiation environment detection and testing capabilities and world-class user service capabilities, and will have the world's leading comprehensive conditions for deep earth physics experiments, and is expected to become the center of the world's deep earth physics experiments. Through the opening of the platform and the sharing of resources, it will promote the major basic frontier research in the fields of particle physics and nuclear physics in China to take the lead in making major breakthroughs. At the same time, it can also play the leading and radiating role of major national scientific and technological infrastructure, form a multidisciplinary cross-integration, resource sharing type of ultra-deep underground ultra-low radiation background research center, innovation base and comprehensive experimental platform, and help create a world-class scientific and technological business card.
Facing the world's frontier of science and technology and the major needs of the country, China Jinping Underground Laboratory has a high reputation at home and abroad, and has attracted the attention of the scientific community at home and abroad. Scientists at home and abroad praised the construction of China's Jinping underground laboratory with words such as "Tsinghua spirit, Yalong River speed" and "corner overtaking". Jinping has gradually become well-known to the world as the frontier of deep earth scientific research.
