Description
Coherent elastic neutrino-nucleus scattering (CEvNS) was predicted in 1974 as a consequence of the weak neutral current. 43 years later, the COHERENT collaboration first observed CEvNS using a 14.6-kg CsI detector. After 3 years, CEvNS on argon was measured using COH-Ar-10 (CENNS-10), 24-kg liquid argon detector. There are many physics opportunities related to CEvNS, but COH-Ar-10 has ~30% statistical uncertainty in the measured cross-section according to the published result. In this talk, I will introduce COH-Ar-750 (CENNS-1ton), a ton-scale liquid argon CEvNS precision detector under construction.
