The DUNE 35ton Prototype at Fermilab

DUNE FD ND 1300 km We have learned much about neutrinos in the last 70 years, but there is still much we don’t understand. DUNE combines a long baseline, an intense neutrino beam and a large liquid argon detector to continue studying neutrinos. The underground location allows us to study proton decay and neutrinos from the sun in addition to the neutrino beam.
