Underground laboratory, especially deep underground laboratory has been very important and key platform for many rare events experiments such as dark matter direct detection, double beta decay, solar neutrino experiments, and the quite long-standing proton decay experiments, and so on. Most of these rare event experiments are the crucial approach to search for new physics above the Standard...

Ultra-pure construction materials are required for the next generation experiments on neutrino physics and dark matter. Copper has excellent mechanical, electrical and, thermal properties and is easily purified by electrochemical methods. Electroforming is an electrochemical process that enables the manufacture of metallic parts with high chemical and radioactive purity, process...

China Jinping underground laboratory (CJPL) is the deepest laboratory in the world and an ideal site for particle physics, astrophysics and other low background experiments. It is located in the Jinping Mountain, Sichuan Province, southwest China, with an overburden of about 2400m. The laboratory is operated by Tsinghua University and Yalong River Hydropower Development Company, LTD. The...

The Black Hills State University Underground Campus (BHUC) located at the Sanford Underground Research Facility in South Dakota was completed in the fall of 2015. Since that time, four ultra-low background, high-purity germanium detectors have been relocated to its class 1,000 cleanroom. More plans are underway for additional germanium detectors as well as other specialized low-background...
69. A development of an ultra-low radioactivity measurement facility at the Center for Underground Physics in Korea
Dr Moo Hyun Lee (IBS)

As a few ultra-low background rare decay experiments at the Yangyang underground laboratory in Korea are being prepared and under operation, a number of ultra-low radioactivity detectors are being developed. For a screening of raw materials or detector components, an ICP-MS, an argon gas ionization counter, a ZnS counter, and a number of High Purity Germanium (HPGe) detectors are developed,...
