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…
