The Korea Invisible Mass Search (KIMS) experiment presents new limits on the weakly interacting massive particle (WIMP)-nucleon cross section using data from an exposure of 3409 kg·d taken with low-background CsI(Tl) crystals at Yangyang Underground Laboratory. most stringent limit spin-dependent interaction for a pure proton case is obtained. DAMA signal region both spin-independent and interactions WIMP masses greater than 20 GeV/c2 excluded by single crystal scintillators.Received 3 April...
The Korea Invisible Mass Search (KIMS) Collaboration has been carrying out WIMP search experiment with CsI(Tℓ) crystal detectors at the YangYang Underground Laboratory. A successful reduction of internal background was done and a good pulse shape discrimination achieved. We report first result on obtained 237 kg days data using one full-size 6.6 mass.
Scintillation properties of calcium molybdate are investigated. The emission spectrum is broad with a maximum at 520 nm. At room temperature the light yield 4% CsI(Tl) (400 photoelectrons/MeV) and decay time 17 /spl mu/s. During cooling increase. Prospects optimization this scintillator also discussed. feasibility material for search neutrinoless double beta /sup 100/Mo analyzed. A half life limit T/sub 1/2/=1/spl middot/10/sup 25/ years (68% CL) seems feasible CaMoO/sub 4/ scintillator,...
Abstract Although the hippocampus has been implicated in both temporal organization of memories and association scene elements, some theoretical accounts posit that role episodic memory is largely atemporal. In this study, we set out to explore discrepancy by identifying hippocampal activity patterns related construction while participants performed a order task. Participants fMRI scanner were shown sequence photographs, each consisting central object contextual background scene. On...
Despite distinct neural representation of what, where, and when information, studies individual differences in episodic memory have neglected to test the three components separately. Here, we used a componential task measure cognitive profiles across wide age range Alzheimer disease (AD) examine role theta oscillations explaining performance. In Experiment 1, tested group 47 young adults (age 21-30 years, 21 women) while recording their scalp EEG. A separate behavioral experiment (Experiment...
KIMS is a dark matter search experiment using low background CsI(TB) crystals at Yangyang Underground Laboratory in Korea. With total exposure of 3409 kg⋅d data, we set new limit on WIMP‐nucleon cross section. We achieved the most stringent spin‐dependent interaction for pure proton case. were able to exclude DAMA signal region both and spin‐independent WIMP mass greater than 20 GeV/c2. upgraded with 12 corresponding 104 kg accumulating data since Jan. 2008.
