معرفی
J.J. Choi is a researcher at Seoul National University's Department of Physics and Astronomy and the Institute for Basic Science (IBS), Center for Underground Physics (CUP) in Daejeon, South Korea. They specialize in dark matter research and particle physics, with a focus on scintillation detector technology using NaI(Tl) crystals.
Dr. Choi's research interests encompass Dark Matter Research, Particle Physics, Scintillation Detectors, Nuclear Physics, and Astroparticle Physics. Their work primarily involves developing and improving detector technologies for dark matter experiments, with particular emphasis on NaI(Tl) crystal-based detection systems, including crystal encapsulation, waveform analysis, and background reduction techniques.
Analysis of Dr. Choi's recent publications reveals a strong focus on advancing NaI(Tl) detector technology for dark matter searches. Their research spans detector development, signal processing, and background modeling essential for sensitive dark matter detection at low energy thresholds. Key contributions include lowering the detection threshold to 0.7 keV and improving background modeling for the COSINE-100 experiment.
- Major publications focus on NaI(Tl) crystal properties
- Key contributor to COSINE-100 and NEON collaborations
- Research addresses critical challenges in dark matter detection
Dr. Choi is actively involved in the COSINE-100 collaboration, designed to verify the DAMA/LIBRA annual modulation signal using the same NaI(Tl) target material, and the NEON experiment, representing Korea's next-generation dark matter detector program. They also contribute to Yemilab, Korea's new underground laboratory facility for particle astrophysics research.
