Coherent Elastic Neutrino-Nucleus Scattering(CEvNS) is a neutral-current neutrino interaction that has recently been observed by the COHERENT Collaboration. COHERENT has deployed detectors with a range of target nuclei to the Spallation Neutron Source at Oak Ridge National Laboratory.
As part of this effort, a single-phase liquid argon detector, CENNS-10, was deployed to the SNS in Fall 2016, and the 24kg fiducial volume target has recently made the first low-N measurement of CEvNS. Using the lessons learned from running CENNS-10, a ton-scale single-phase liquid argon detector, CENNS-750, is currently being designed and prototyped. CENNS-750 is expected to see around 20 times more CEvNS events per year than CENNS-10 as well as be sensitive to inelastic neutrino events. Development of CEvNS detection capabilities also provides tools for direct dark matter WIMP searches. Current progress on CENNS-750 will be presented.
A ton-scale single phase liquid argon detector for measuring CEvNS is currently in development.
