The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory is a pulsed source of neutrons and, as a by-product of this operation, an intense source of pulsed neutrinos via stopped-pion decay. The COHERENT collaboration uses this source to investigate coherent elastic neutrino-nucleus scattering and other physics with a suite of detectors. This work includes a description of our geant4 simulation of neutrino production at the SNS and the flux calculation which informs the COHERENT studies. We estimate the uncertainty of this calculation at the ∼10% level based on validation against available low-energy π+ production data.9 MoreReceived 31 March 2022Accepted 7 July 2022DOI:https://doi.org/10.1103/PhysRevD.106.032003Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
