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…
Background modeling for dark matter search with 1.7 years of COSINE-100 data
G. Adhikari, P. Adhikari, E. Barbosa de Souza +47
We present a background model for dark matter searches using an array of NaI(Tl) crystals in the COSINE-100 experiment that is located in the Yangyang underground laboratory. The m…
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…
Study of cosmogenic radionuclides in the COSINE-100 NaI(Tl) detectors
E. Barbosa de Souza, B. J. Park, G. Adhikari +48
COSINE-100 is a direct detection dark matter search experiment that uses a 106 kg array of eight NaI(Tl) crystals that are kept underground at the Yangyang Underground Laboratory t…
Search for a Dark Matter-Induced Annual Modulation Signal in NaI(Tl) with the COSINE-100 Experiment
100 Collaboration, G. Adhikari, P. Adhikari +46
We present new constraints on the dark matter-induced annual modulation signal using 1.7 years, of COSINE-100 data with a total exposure of 97.7 kgyears. The COSINE-100 expe…
The First Direct Search for Inelastic Boosted Dark Matter with COSINE-100
C. Ha, G. Adhikari, P. Adhikari +45
A search for inelastic boosted dark matter (iBDM) using the COSINE-100 detector with 59.5 days of data is presented. This relativistic dark matter is theorized to interact with the…
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…
Understanding NaI(Tl) crystal background for dark matter searches
G. Adhikari, P. Adhikari, C. Ha +8
We have developed ultra-low-background NaI(Tl) crystals to reproduce the DAMA results with the ultimate goal of achieving purity levels that are comparable to or better than those…
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…
Pulse-shape discrimination between electron and nuclear recoils in a NaI(Tl) crystal
H. S. Lee, G. Adhikari, P. Adhikari +24
We report on the response of a high light-output NaI(Tl) crystal to nuclear recoils induced by neutrons from an Am-Be source and compare the results with the response to electron r…
