Neutrino-Induced Neutron Detectors at the Spallation Neutron Source

Not scheduled


Dr Jacob Daughhetee (University of Tennessee)


The COHERENT collaboration seeks to measure neutrino interaction cross sections using the high-intensity, pulsed neutrino flux provided by the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL). In addition to ongoing CEvNS measurements, the collaboration deploys a set of detectors dedicated to the observation of neutrons produced via neutrino interactions in iron and lead, common shielding materials. Neutrino-nucleus interactions in the shielding material can yield excited nuclear states which may decay via the emission of neutrons. These neutrino-induced neutrons (NINs) represent a potential background for CEvNS measurements as well as a detection channel for SNe neutrinos. However, current theoretical cross sections suffer from large uncertainty. The design, operations, and analysis status of COHERENT's NIN detectors will be presented.


Detectors search for neutrino-induced neutrons, a possible background for rare event searches.
