“The Status of Center for Underground Physics (CUP), Institute for Basic Science”

We have performed some pioneering experiments for dark matter search and double beta decay experiments at Yangyang Laboratory (Y2L) in South Korea for last 15 years. Since year of 2013, a new research center in the Institute for Basic Science (IBS), Center for Underground Physics (CUP), is approved by the government. Due to the limited space in Y2L, we are constructing a new underground laboratory at 1100 meter depth with a space of more than 2000 square meters by the end of 2019.

CUP has two main experimental programs; (1) Identification of dark matter and (2) Neutrinoless double beta decay search. Experimentalists at Yale University and CUP are conducting a 100kg-scale low background NaI(Tl) crystal experiment (COSINE-100) which will be discussed extensively in this collaboration meeting. AMoRE (Advanced Mo-based Rare phenomena Experiment) is a state-of-art experiment based on low temperature MMC sensor and ultra pure molybdate crystals containing highly enriched isotopes. The sensitivity reach 1027 years of half-life and down to 15-30 meV of neutrino mass by running 5 years with 200 kg of molybdate crystals. In addition to the two main programs, a short baseline neutrino experiment (NEOS) has been conducted and the future perspectives are discussed. The general concept and goal of CUP will be briefly described.
