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…
Performance of an ultra-pure NaI(Tl) detector produced by an indigenously-developed purification method and crystal growth for the COSINE-200 experiment
Hyun Seok Lee, Byung Ju Park, Jae Jin Choi +17
The COSINE-100 experiment has been operating with 106 kg of low-background NaI(Tl) detectors to test the results from the DAMA/LIBRA experiment, which claims to have observed dark…
NaI(Tl) crystal scintillator encapsulated in two organic-scintillator layers with pulse shape data analysis
Jinyoung Kim, Yujin Lee, Byoung-cheol Koh +4
Thallium-doped sodium iodide (NaI(Tl)) crystals are widely used in radiation detection applications, from gamma-ray spectroscopy to particle dark matter searches. However, if the c…
A facility for mass production of ultra-pure NaI powder for the COSINE-200 experiment
Keonah Shin, Junseok Choe, Olga Gileva +6
COSINE-200 is the next phase of the ongoing COSINE-100 experiment. The main purpose of the experiment is the performance of an unambiguous verification of the annual modulation sig…
Lowering the energy threshold in COSINE-100 dark matter searches
G. Adhikari, E. Barbosa de Souza, N. Carlin +43
COSINE-100 is a dark matter detection experiment that uses NaI(Tl) crystal detectors operating at the Yangyang underground laboratory in Korea since September 2016. Its main goal i…
Comparison between DAMA/LIBRA and COSINE-100 in the light of Quenching Factors
Y. J. Ko, K. W. Kim, G. Adhikari +46
There is a long standing debate about whether or not the annual modulation signal reported by the DAMA/LIBRA collaboration is induced by Weakly Interacting Massive Particles~(WIMP)…
A search for solar axion induced signals with COSINE-100
P. Adhikari, G. Adhikari, E. Barbosa de Souza +45
We present results from a search for solar axions with the COSINE-100 experiment. We find no evidence of solar axion events from a data-set of 6,303.9 kgdays exposure and se…
Quenching factor measurement for NaI(Tl) scintillation crystal
H. W. Joo, H. S. Park, J. H. Kim +4
Scintillation crystals are commonly used for direct detection of weakly interacting massive particles (WIMPs), which are suitable candidates for a particle dark matter. It is well…
The COSINE-100 Data Acquisition System
100 Collaboration, G. Adhikari, P. Adhikari +44
COSINE-100 is a dark matter direct detection experiment designed to test the annual modulation signal observed by the DAMA/LIBRA experiment. COSINE-100 consists of 8 NaI(Tl) crysta…
Study of fast neutron detector for COSINE-100 experiment
G. Adhikari, P. Adhikari, C. Ha +11
A monitoring system for fast neutrons is planned in the COSINE experiment, a dark matter experiment with NaI crystals. We pursued several R&D approaches for a neutron detector usin…
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…
Initial Performance of the COSINE-100 Experiment
G. Adhikari, P. Adhikari, E. Barbosa de Souza +49
COSINE is a dark matter search experiment based on an array of low background NaI(Tl) crystals located at the Yangyang underground laboratory. The assembly of COSINE-100 was comple…
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…
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…
Neutron calibration facility with an Am-Be source for pulse shape discrimination measurement of CsI(Tl) crystals
H. S. Lee, H. Bhang, J. H. Choi +19
We constructed a neutron calibration facility based on a 300-mCi Am-Be source in conjunction with a search for weakly interacting massive particle candidates for dark matter. The f…
