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…
Validation of the COSINE-100U NaI(Tl) Encapsulation for Low-Temperature Operation in Liquid Scintillator
Kihong Park, Sungjin Cho, Luis Eduardo Franca +12
The COSINE-100U (upgrade) will enhance the sensitivity of the COSINE-100 dark matter search by operating the detector array immersed in liquid scintillator (LS) at . To val…
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…
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…
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…
