Abstract
Search for weakly interacting massive particles (WIMPs) is being carried out at the underground laboratory, Yangyang, Korea. Characteristics and internal background of CsI(T ℓ ) crystal have been investigated. In our extensive R&D, we reduced internal background in the CsI ( T ℓ ) crystal. With the latest, we have achieved 5.50 ± 0.10 cpd (counts/keV/kg/day) at 10–15 keV low-energy region. Further reduction of internal background is foreseen with the CsI powder lately produced.
