Summary
Among the Deep Underground Neutrino Experiment's main goals are the
precise measurement of neutrino oscillation parameters using a beam
consisting primarily of $\nu_\mu$ or $\bar{\nu_\mu}$ but with
contamination from wrong-sign and wrong-flavor neutrinos. The
uncertainties on the flux predictions and the interaction cross
sections are large and they will require experimental constraints in order
for the DUNE experiment to have maximal sensitivity. Furthermore, biases
in the energy scale of the DUNE far detector are sensitive to cross
sections, especially for neutron production, that are currently poorly
understood. The proposed detectors at the Fermilab near site are
described -- the pixel liquid-argon time projection chamber, a
magnetized high-pressure gaseous argon time projection chamber with an
integrated electromagnetic calorimeter, and a 3D scintillator-tracker.
Each of these three detectors provides unique capabilities necessary
to constrain the flux and cross section uncertainties necessary to
make precise oscillation measurements.
