N2 - Measurements of the high-energy neutron flux spectra at the Spallation Neutron Source (SNS) are underway. The measurement technique activates multiple foils in the neutron beams, and then uses gamma spectroscopy to determine the activity due to threshold reactions. These activity measurements are used as input to the MAXED unfolding code, which outputs an unfolded neutron spectrum consistent with the measurements. Preliminary results measured at the ARCS beamline indicate the unfolded spectrum from 20 Mev to 120 MeV agrees with the predicted spectrum by a relative dose rate metric ΔḢ/Ḣ=0.06. Additional measurements are planned to confirm and improve this result.
