Description
The Deep Underground Neutrino Experiment (DUNE) is a long-baseline neutrino oscillation experiment using an accelerator neutrino beam produced at Fermilab. Additionally, the far detector, four liquid argon time projection chambers, each with 10 kt of fiducial mass, with an overburden of 4300 mwe, is sensitive to a rich range of astroparticle measurements. In this talk, we outline DUNE’s expected sensitivity to measuring the solar neutrino flux. We are sensitive to charged current scattering off argon and neutrino-electron elastic scattering, leading to two separate flux measurements DUNE can achieve. However, we expect large radiological background rates from capture of neutrons generated in the detector cavern and inelastic alpha-Ar interactions from alpha-emitting isotopes in the 222Rn decay chain within the detector volume. We focus on the triggering and reconstruction of solar neutrino events along with simulated predictions for expected background rates.
