A Study of NaI(Tl) crystal Encapsulation using Organic scintillators for the Dark Matter Search
J. Y. Lee, G. Adhikari, C. Ha +5
Scintillating NaI(Tl) crystals are used for various rare decay experiments, such as dark matter searches. The hygroscopicity of NaI(Tl) crystal makes the construction of crystal de…
Background model for the NaI(Tl) crystals in COSINE-100
P. Adhikari, G. Adhikari, E. Barbosa de Souza +46
The COSINE-100 dark matter search experiment is an array of NaI(Tl) crystal detectors located in the Yangyang Underground Laboratory (Y2L). To understand measured backgrounds in th…
Measurement of low-energy background events due to Rn contamination on the surface of a NaI(Tl) crystal
K. W. Kim, C. Ha, N. Y. Kim +4
It has been known that decays of daughter elements of Rn on the surface of a detector cause significant background at energies below 10 keV. In particular Pb and $^…
Performance of a prototype active veto system using liquid scintillator for a dark matter search experiment
J. S. Park, P. Adhikari, G. Adhikari +7
We report the performance of an active veto system using a liquid scintillator with NaI(Tl) crystals for use in a dark matter search experiment. When a NaI(Tl) crystal is immersed…
Tests on NaI(Tl) crystals for WIMP search at the Yangyang Underground Laboratory
K. W. Kim, W. G. Kang, S. Y. Oh +17
Among the direct search experiments for WIMP dark matter, the DAMA experiment observed an annual modulation signal interpreted as WIMP interactions with 9.2 significance. Howeve…
