Coherent elastic neutrino-nucleus scattering (CEvNS) was predicted as a consequence of the existence of neutral current and is the dominant neutrino scattering channel for neutrino energies below 50 MeV. We observed CEvNS on an argon target using the CENNS-10 detector, a 24-kg single-phase liquid argon detector, but with a statistical uncertainty of approximately 30%. To improve the precision of the measurement and to probe various physics topics in the low-energy Weak Interaction range, CENNS-1ton, a ton-scale single-phase liquid argon detector, has been designed, constructed, and tested at Seoul National University, Korea. After initial tests at SNU, the detector was relocated to the Neutrino Alley of Spallation Neutron Source at Oak Ridge National Laboratory for commissioning and neutrino source experiments. In this talk, I will report on the current status of the CENNS-1 ton experiment. I will also cover a few topics in detector R&D aimed at discovering various low-energy particle interactions.
