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…
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…
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…
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…
