Neutrino Elastic-scattering Observation with NaI[Tl](NEON)

Abstract

Standard-Model predicts the coherent elastic neutrino-nucleus scattering, which is interesting for the measurement of the neutrino properties and demonstration of the possibility of WIMP-nucleus interaction. The process hasn't been detected for reactor neutrinos yet. For this measurement, a NaI(Tl) array detector with high light yield and a low threshold will be used. The Hanbit reactor site in Korea provides 2.8 GW of thermal power and 7.1$\times$10$^{12}$ cm$^{-2}$s$^{-1}$ of neutrino flux to the detector located at 24 m away from the reactor core. The current research shows that a light yield of a crystal is around 23 photoelectrons(PE)/keV which would make a sub-keV scintillation signal detectable. The target mass of NEON(Neutrino Elastic-scattering Observation with NaI(Tl)) will be 10 kg, surrounded by a liquid scintillator veto detector, and passive shieldings.
