Description
Taking advantage of recent NaI crystal detector development, we established stable data-taking of the NEON experiment with a 16.7 kg crystal array at 23.7 meters away from the reactor core of the Hanbit nuclear power plant (2.8-GWth) in April 2022. NEON aims at detecting a coherent neutrino-nucleus scattering process for reactor antineutrinos.
Using preliminary analyses of approximately 150 (143) days of reactor-ON(OFF) data, we found that the detector performs stably and better than expected, reaching crystal light yield of the unprecedented 24 photoelectrons per 1 keV energy deposit. Until now, 6 counts/day/kg/keV of the single-hit background rate at 0.6 keV have been achieved. The status of the experiment and its expected sensitivity assuming 0.2 keV energy threshold depending on quenching systematics will be reported.
