Development and Initial Performance of an Upgraded NaI(Tl) Crystal Encapsulation for COSINE-100U
Doohyeok Lee, Jae Young Cho, Chang Hyon Ha +23
The COSINE-100 experiment was designed to test the DAMA/LIBRA annual-modulation claim using low-background NaI(Tl) detectors. For the COSINE-100U upgrade, we developed a new crysta…
Upgrading the COSINE-100 Experiment for Enhanced Sensitivity to Low-Mass Dark Matter Detection
D. H. Lee, J. Y. Cho, C. Ha +23
The DAMA/LIBRA experiment has reported an annual modulation signal in NaI(Tl) detectors, which has been interpreted as a possible indication of dark matter interactions. However, t…
COSINE-100 Full Dataset Challenges the Annual Modulation Signal of DAMA/LIBRA
N. Carlin, J. Y. Cho, J. J. Choi +56
For over 25 years, the DAMA/LIBRA collaboration has claimed to observe an annual modulation signal, suggesting the existence of dark matter interactions. However, no experiment emp…
Lowering threshold of NaI(Tl) scintillator to 0.7 keV in the COSINE-100 experiment
G. H. Yu, N. Carlin, J. Y. Cho +56
COSINE-100 is a direct dark matter search experiment, with the primary goal of testing the annual modulation signal observed by DAMA/LIBRA, using the same target material, NaI(Tl).…
First Direct Search for Light Dark Matter Using the NEON Experiment at a Nuclear Reactor
J. J. Choi, C. Ha, E. J. Jeon +14
We report new results from the Neutrino Elastic Scattering Observation with NaI (NEON) experiment in the search for light dark matter (LDM) using 2,636 kgdays of NaI(Tl) exp…
New Constraints on Axion-Like Particles with the NEON Detector at a Nuclear Reactor
Byung Ju Park, Jae Jin Choi, Eunju Jeon +17
We report new constraints on axion-like particles (ALPs) using data from the NEON experiment, which features a 16.7 kg of NaI(Tl) target located 23.7 meters from a 2.8 GW thermal p…
