Precision measurement of ocean tides using cosmic-ray muons

Jiwon Seo, Jongseok Chung, Chang Hyon Ha +8

Cosmic-ray muons provide a natural probe of the integrated mass along their trajectories. Here we show that cosmic-ray muons can monitor ocean-tide-induced variations in seawater o…

Charged-particle topology reconstruction with an in-liquid SiPM array

H. Kimku, J. S. Chung, C. Ha +8

Liquid scintillator detectors instrumented with photosensors inside the scintillation volume preserve local optical information that is largely lost in conventional boundary-readou…

Characterization of immersed SiPM arrays in liquid scintillator between room temperature and

M. S. Kwak, J. S. Chung, C. Ha +9

Liquid scintillator detectors instrumented with distributed silicon photomultiplier (SiPM) arrays can be used in compact, topology-sensitive, and low-background experiments, but th…

Pulse shape discrimination in an organic scintillation phoswich detector using machine learning techniques

Yujin Lee, Jinyoung Kim, Byoung-cheol Koh +2

We developed machine learning algorithms for distinguishing scintillation signals from a plastic-liquid coupled detector known as a phoswich. The challenge lies in discriminating s…
