The COSINE-100U experiment upgrades the COSINE-100 detector to improve the search for dark matter interactions using ultra-low background NaI(Tl) crystals. By enhancing light collection efficiency and reducing background noise through a new encapsulation design, the experiment achieves higher sensitivity, advancing the investigation of the DAMA/LIBRA annual modulation signal.
