Neutrino Physics at the ORNL Spallation Neutron Source

ORAL  · Invited

Abstract

In recent years, Oak Ridge National Laboratory's Spallation Neutron Source (SNS) has proven itself as one of the world's premier stopped pion neutrino sources, due to the high neutrino flux, well-understood neutrino spectrum, and a timing structure that enables significant reductions of steady-state backgrounds. The COHERENT Collaboration has made effective use of the SNS to make the world's first measurements of Coherent Elastic Neutrino Nucleus Scattering (CEvNS), and constrain beyond-the-standard-model physics such as Non-Standard Neutrino Interactions (NSIs) and accelerator-produced dark matter. As plans for construction of a Second Target Station (STS) and an associated beam power upgrade develop, opportunities arise for enabling future fundamental physics searches at this unique facility. We will discuss performing neutrino physics measurements at the SNS, including recent results and developments by the COHERENT Collaboration, and future possibilities associated with the STS.
