Commissioning of the Neutron Irradiation Station at the University of Notre Dame

We have developed and commissioned the Neutron Irradiation Station (NIS) facility at the University of Notre Dame Nuclear Science Laboratory, which produces high-flux, quasi-monoenergetic neutrons via the reaction ⁷Li(p,n) for use in neutron-induced reaction measurements for nuclear energy and stockpile stewardship applications. To commission NIS, neutron energy distributions were characterized for various proton energies and neutron standard foils were activated to determine neutron fluxes at different locations relative to the production target. This presentation will discuss neutron energy spectra and flux results as well as plans for upcoming reaction measurements with NIS.
