Probing unexplored spin-dependent dark matter-proton coupling with few-photoelectron threshold in COSINE-100
W. K. Kim, N. Carlin, J. Y. Cho +58
We report new constraints on the spin-dependent scattering cross section between low-mass dark matter and protons using data collected by the COSINE-100 experiment. By implementing…
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).…
Nonproportionality of NaI(Tl) Scintillation Detector for Dark Matter Search Experiments
S. M. Lee, G. Adhikari, N. Carlin +59
We present a comprehensive study of the nonproportionality of NaI(Tl) scintillation detectors within the context of dark matter search experiments. Our investigation, which integra…
Scintillation characteristics of an undoped CsI crystal at low-temperature for dark matter search
W. K. Kim, H. Y. Lee, K. W. Kim +4
The scintillation characteristics of 1 g undoped CsI crystal were studied by directly coupling two silicon photomultipliers(SiPMs) over a temperature range from room temperature to…
Alpha backgrounds in NaI(Tl) crystals of COSINE-100
G. Adhikari, N. Carlin, D. F. F. S. Cavalcante +60
COSINE-100 is a dark matter direct detection experiment with 106 kg NaI(Tl) as the target material. 210Pb and daughter isotopes are a dominant background in the WIMP region of inte…
