The COHERENT neutrino experiment at the Spallation Neutron Source

ORAL

Abstract

The COHERENT collaboration employs a collection of neutrino detectors at the ORNL Spallation Neutron Source (SNS) to detect Coherent Elastic Neutrino Nucleus Scattering (CEvNS) and other neutrino interactions. The pulsed 1 GeV proton beam on a liquid mercury target provides a bright source of pion decay-at-rest neutrinos. The collaboration has measured CEvNS cross sections on multiple target nuclei, and also measured charged-current interactions in a well-shielded hallway at the SNS known as "neutrino alley". These measurements offer a test of the Standard Model and improve our understanding of neutrino-nuclear interactions in the 0-50 MeV range. Improved precision relies on the continued operation of detectors in neutrino alley, upgrading to larger detectors, and refining our knowledge of the neutrino flux. In this talk I will present an overview of recent results from the collaboration and highlight ongoing work to deploy the next-generation suite of detectors.
