OscSNS: Precision Neutrino Measurements at the Spallation Neutron Source

Abstract

The Spallation Neutron Source (SNS), located at Oak Ridge Laboratory in the United States, will be coming online over the next few years. In addition to producing fluxes of high-intensity neutrons, the interaction of the proton beam with the liquid mercury target produces copious pions. The pi+ and subsequent mu+ decay at rest, providing a neutrino beam comprising numu, nue, and anti-numu components. This neutrino beam is ideal for high-precision neutrino experiments. OscSNS is a proposed multi-purpose experiment that will perform a search for light sterile neutrinos, search for beyond the Standard Model interactions using neutrino oscillations, and provide tests of Standard Model predictions through world-record precision neutrino cross section measurements. OscSNS plans to submit a full proposal for funding in 2009.
