Description

The Coherent elastic scattering of neutrinos off nuclei was predicted over 40 years ago after the realization of the neutral weak current. This standard-model process remains unobserved due to the daunting technical requirements: very low nuclear recoil energy thresholds, intense sources/large target masses, and low backgrounds. Employing state-of-the-art low-energy-threshold detector technology coupled with the intense stopped-pion neutrino source available at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL), the COHERENT Collaboration aims to measure CEvNS and to use it as a tool to search for physics beyond the standard model. A suite of detector systems (CsI[Na] and NaI[Tl] scintillating crystals, p-type point-contact germanium detectors, and single-phase liquid argon (LAr) is being deployed in the basement of the SNS, taking advantage of decades of detector development in the dark-matter direct-detection community. The first-phase of the COHERENT multi-detector approach will enable unambiguous discovery of CEvNS and test for non-standard neutrino interactions. This systematic characterization of low-threshold recoil detectors will validate experimental background and detector-response models, given that CEvNS of natural neutrinos is an irreducible background for dark matter WIMP searches. As secondary goals, COHERENT will perform measurements of the charged-current cross sections on I, Pb, Fe, and Cu; the last three of which result in the emission of background-inducing fast neutrons. The measurement of this cross section on lead also has implications for supernova neutrino detection in the HALO supernova neutrino detector.
