Description

Neutrino interactions with a ton-scale liquid argon detector for the COHERENT experiment

The COHERENT collaboration operates an array of detectors at the ORNL Spallation Neutron Source (SNS) to measure coherent elastic neutrino nucleus scattering (CEvNS), low-energy inelastic neutrino interactions, and to search for dark matter. We observed the first CEvNS events in 2017 with a cesium-iodide scintillation detector. We followed up with a measurement using a 24 kg liquid argon detector (CENNS-10) thus confirming the CEvNS hypothesis. COHERENT is expanding in the next years with more detectors to increase the precision of those results thur increasing our physics reach into beyond-standard-model physics tests. As part of that, we are building a 750 kg liquid argon scintillation detector (COHAr-750) that will increase the event rate substantially to allow precision measurements of the CEvNS process as well as allow sensitivity to inelastic neutrino processes and accelerator-produced dark-matter. In this talk we will present the physics topics that will be investigated along with design details of COHAr-750.
