The direct detection of dark matter is a crucial component in the search for the Universe's missing matter. In Korea, this research was started by Professors Sun-Kee Kim, Yeoungduk Kim, and Hong-Joo Kim, who in 1997 discussed the possibility of a dark matter search using CsI(Tl) crystals. In 1999, the Korea Invisible Mass Search (KIMS) collaboration was formed at CheongPyung Underground Laboratory. The KIMS collaboration secured a deeper place, the Yangyang Underground Laboratory, in 2003 and started its dark-matter search experiment with CsI(Tl) crystals. Since 2013, the research has been extended to develop ultra-low-background NaI(Tl) crystals, as well as cryogenic detectors, for the dark-matter search. In this article, we review the achievements of the dark-matter search experiment, as well as the future plan, at KIMS.

대부분의 우주 구성 질량으로 생각되는 암흑물질을 지구에서 직접 발견하는 것은 과학적으로 매우 흥미롭고 중요한 과제이다. 한국에서는 1997년 김선기, 김영덕, 김홍주 교수를 중심으로 CsI(Tl) 검출기를 암흑물질 탐색에 사용하는 연구를 시초로, 1999년 청평 지하실험실을 구축하고 KIMS (Korea Invisible Mass Search) 실험을 시작하였다. KIMS 연구진은 2003년부터 심도가 깊은 양양 지하실험실로 이전하여 CsI(Tl) 검출기를 이용한 본격적인 실험을 진행하였으며 2013년부터 극저방사능 NaI(Tl) 검출기 및 저온 검출기 개발에 뛰어들어 암흑물질 직접 탐색에 매진하고 있다. 본 논문에서는 KIMS 실험이 현재까지 진행한 암흑물질 탐색 실험의 성과와 향후 계획에 대해 논의하고자 한다.
