The Dune Experiment

Neutrino oscillation is a quantum mechanical phenomenon whereby a neutrino, produced with a certain lepton flavor, can be detected with a different lepton flavor. This behavior was predicted by Bruno Pontecorvo in 1957 and it was experimentally observed for the first time in 1998. Since then many experiments have tried to measure the parameters describing the oscillations. The Deep Underground Neutrino Experiment (DUNE) will observe neutrinos produced by a high-power, broadband neutrino beam by means of two detectors, one close to the neutrino source (Near Detector) at Fermilab in Batavia (Illinois) and the other one at 1300 km at the Sanford Underground Research Facility in South Dakota. Thanks to an high-precision near detector and large liquid argon time-project chambers (LArTPC) as far detector, after 6 years of data taking, DUNE will precisely measure the oscillation parameters governing electron neutrino appearance and muon neutrino disappearance, with sufficient precision to discover leptonic CP violation and to determine the neutrino mass hierarchy. In addition neutrinos from a core-collapse supernova will be detected and search for baryon number violating processes such as nucleon decay can be investigated. Currently two prototypes Far Detector are under construction and test at CERN. The first takes data since September 2018, while since 2017 the construction of the Sanford Lab infrastructure has been started. DUNE is an international collaboration, including more than 20 countries and 1000 collaborators. The Genoa group is involved in the Near Detector design and simulations and in the photo sensor development and test for the Far Detector.
