Big discoveries need big detectors, and Fermilab’s Deep Underground Neutrino Experiment is one of the biggest. Fermilab plans to shoot beams of neutrinos and antimatter neutrinos through the Earth from Chicago to western South Dakota. The DUNE experiment will study neutrino interactions in great detail, with special attention on (a) comparing the behaviors of neutrinos vs. antineutrinos, (b) looking for proton decay, and (c) searching for the neutrinos emitted by supernovae. The experiment is being built and should start operations in the mid-to-late 2020s. In this video, Fermilab’s Dr. Don Lincoln gives us the lowdown on this fascinating project.
