标准模型预言了中微子-原子核的相干弹性散射，这对于测量中微子的性质和论证WIMP-原子核相互作用的可能性很有意义。目前还没有检测到反应堆中微子的这一过程。
对于这种测量，将使用具有高光产额和低阈值的NaI(Tl)阵列探测器。
韩国汉比特反应堆场址向距离反应堆堆芯24m的探测器提供2.8GW的热功率和7.1倍的中微子通量S。
目前的研究表明，晶体的光产额约为23个光电子(PE)/keV，这将使亚keV闪烁信号可被探测到。
Neon的目标质量(用NaI(Tl)进行的中微子弹性散射观测)将是10公斤，周围有一个液体闪烁体否决权探测器和被动屏蔽。
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.
