The facility will aim a wide band beam of neutrinos toward a detector placed at the Sanford Underground Research Facility in South Dakota, about 1,300 km away. The main elements of the facility are a primary proton beamline and a neutrino beamline. The primary proton beam (60 -120 GeV) will be extracted from the MI-10 section of Fermilab's Main Injector. Neutrinos are produced after the protons hit a solid target and produce mesons wh","authors_text":"A. Marchionni, C.D. Moore, J. Hylen, P. Schlabach, R. Andrews, S. Tariq (Fermilab), T.
