Description
Coherent elastic neutrino-nucleus scattering (CEvNS) has been detected in a 24 kg single-phase liquid argon (LAr) scintillator detector. Further data has been collected for a 5σ measurement and analysis is ongoing. To obtain an event rate 20 times that of the 24 kg detector, a 750 kg LAr scintillator detector has been designed by the COHERENT collaboration to be deployed at the Spallation Neutron Source at Oak Ridge National Laboratory. This tonne-scale detector is designed to operate at a low threshold to do a precision measurement of the CEvNS recoil spectrum, which can be used to probe other physics such as non-standard neutrino interactions. Unlike the 24 kg detector, the 750 kg detector will be sensitive to inelastic charged-current and neutral-current events. It will allow for a stringent limit to be placed on light accelerator produced dark matter. This poster will be an update on the work done towards a 750 kg detector. It will focus on light collection tests and status of simulations.
