A NaI is conventional detector with a very long history and are still widely used. In particular, since the DAMA experiment claimed an observation of dark matter with the NaI(Tl) detector, the development of a low background and high scintillation efficiency detectors were widely researched.
In Korea, the COSINE experiment to verify the DAMA experiment by developing a high-purity NaI detector at the Center for Underground Physics in IBS is being operated at the Yangyang Underground Laboratory and reported interesting results. In addition, COSINE collaboration is preparing for the next phase COSINE-200 experiment by developing the world's best performing high-purity NaI detector. In addition, several efforts are underway to increase the light yield and the detector performances. Based on the results of these efforts, the NEON experiment, an experiment to observe the neutrino-nucleus coherent scattering from the electron antineutrinos in a nuclear power plant that requires an extremely low energy threshold, was started. In this presentation, we want to show the efforts and achievements on the development of high-purity NaI detectors for dark matter and neutrino experiments.
