Preventing quart-NaI adhesion in Bridgman growth using ammonium iodide
Lam Tan Truc, N. T. Luan, Gul Rooh +7
Adhesion between NaI(Tl) single crystals and the walls of quartz ampoules remains a major limitation for Bridgman growth under sealed conditions, particularly for applications requ…
Development of a 10 mol% Rubidium-doped CsI Crystal for Rb Beta-Spectroscopy and Sterile Neutrino Searches
W. K. Kim, K. W. Kim, L. T. Truc +3
The third-forbidden non-unique beta-decay of Rb to Sr (Q keV) has long served as an important benchmark for understanding forbidden beta-decay. To inv…
Limits on WIMP dark matter with NaI(Tl) crystals in three years of COSINE-100 data
G. H. Yu, N. Carlin, J. Y. Cho +56
We report limits on WIMP dark matter derived from three years of data collected by the COSINE-100 experiment with NaI(Tl) crystals, achieving an improved energy threshold of 0.7 ke…
Combined Annual Modulation Dark Matter Search with COSINE-100 and ANAIS-112
N. Carlin, J. Y. Cho, J. J. Choi +71
The annual modulation signal, claimed to be consistent with dark matter as observed by DAMA/LIBRA in a sodium-iodide based detector, has persisted for over two decades. COSINE-100…
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).…
