Electron-neutrino inelastic charged-current scattering on argon with COHERENT at the SNS

Electron-neutrino inelastic charged-current scattering on argon, the dominant supernova neutrino interaction channel in the upcoming Deep Underground Neutrino Experiment, has never been measured at energies below 52 MeV. Using low energy neutrinos produced by pion decay at rest at the Spallation Neutron Source at Oak Ridge National Lab, the COHERENT collaboration will measure this interaction. COHERENT has recently decommissioned the COH-Ar-10 detector, a 24 kg single-phase liquid argon scintillator detector, that has over 18.5 GWhr exposure of POT. This exposure will be used to perform a search for low-energy electron-neutrino inelastic charged-current scattering on argon. COH-Ar-750, an upgraded, tonne-scale liquid argon scintillator detector, is currently being deployed. Unlike COH-Ar-10, COH-Ar-750 will employ a muon veto to achieve precision measurement of electron-neutrino inelastic charged-current scattering on argon. The status of the COH-Ar-10 charged-current scattering analysis and the COH-Ar-750 muon veto will be presented.
