The Deep Underground Neutrino Experiment (DUNE) will make a beam of muon neutrinos or antineutrinos at Fermilab starting in 2026. This beam will pass through two detectors: the near detector will be 574 metres from the target and will consist of a liquid argon time projection
chamber (LArTPC) and either a straw-tube tracker or a high-pressure argon gas TPC, while the far detector will be a suite of 4 LArTPCs located at a distance of 1300 km from Fermilab. These detectors will be on the axis of the beam, which will give neutrino flux over a broad range of energies including the first and second oscillation maxima. Sensitivity studies are presented that suggest that, in 7 years’ running, DUNE will be able to resolve the neutrino mass hierarchy to at least $\sqrt{∆χ^{2}}$ = 5 for all true values of $δ_{CP}$ using beam neutrinos. In 10 years’ running, DUNE will be able to measure $δ_{CP}$ to better than 10 degrees if its true value is 0 or better than 20 degrees if it is π, resolve the $θ_{23}$ octant with 5σ significance if the true value of sin$^{2} θ_{23}$ is ≤ 0.45 or ≥ 0.57, and make precise measurements of other neutrino oscillation parameters.
