Abstract: KIMS is a dark matter search experiment using low background CsI(Tl) crystals at Yangyang Underground Laboratory in Korea. With a total exposure of 3409 kg-d data, we set a new limit on WIMP-nucleon cross section. We achieved the most stringent limit on the spin-dependent interaction for a pure proton case. We were able to exclude the DAMA signal region for both spin-dependent and spin-independent interaction for the WIMP mass greater than 20 GeV/c 2. KIMS experiment is upgraded with 12 CsI(Tl) crystals corresponding to a total mass of 104 kg and accumulating data since Jan. 2008. © 2008 American Institute of Physics.
