Abstract

In this technical note, we present the analysis and results of neutron data collected in 2018 at the Spallation Neutron Source (SNS) by the MARS neutron detector and spectrometer. MARS has been deployed at the SNS "neutrino alley' basement with the purposed of monitoring and characterizing the neutron backgrounds for the COHERENT collaboration. The measured beam neutron rates at the MARS deployment location near some of the COHERENT neutrinos detectors are presented and we discuss what the measured rate and spectra can tell us about the incoming beam neutron flux and energy distribution.
