provides an intense flux of neutrinos in the few tens-of-MeV range, with a sharply-pulsed
timing structure that is beneficial for background rejection. In this white paper, we describe
how the SNS source can be used for a measurement of coherent elastic neutrino-nucleus
scattering (CENNS), and the physics reach of different phases of such an experimental
program (CSI: Coherent Scattering Investigations at the SNS).
