Description
The Yemilab, a new deep underground laboratory, has been constructed to be located under the Yemi mountain at the Jeongseon in Korea. The overburden is 1,000 m from the top of the Yemi mountain which may provide 5 times better muon mitigation than Y2L, and the laboratory area is approximately 3,000 m^2 which is 10 times larger than Y2L. We can access the laboratory using a cage that has 4 m/s vertical speed through the 600 m shaft and electric vehicles as transportation through the 800 m tunnel. The electricity, mobile networks, and facility for safety have been prepared for operation since the end of 2022.
Two major physics programs, AMoRE-II to search for a neutrinoless double beta decay of 100Mo and COSINE to search for a WIMP as a strong candidate of dark matter, are preparing to start the initial operation at the end of 2023. To provide a low radioactive background environment for those experiments, the radioactivity of the rock, radon level, muon rates, and neutron flux are measuring and monitored since the initial operation.
We report on the construction of the Yemilab, the current status of the facility for the scientific programs, and discuss future applications.
