The Deep Underground Neutrino Experiment is devoted to precision measurements of neutrino oscillation properties. In particular it will test if they affect equally neutrinos and anti-neutrino muon beams, which will travel 1300 km from Fermilab to SURF.
Small differences are expected due to the fact that neutrinos and anti-neutrinos are crossing a large distance in the matter (and not anti-matter) of the Earth’s crust – and measuring these will allow to finally set the order of the three neutrino masses.
Extra differences will arise if neutrino mixing does not obey the common charge-parity (CP) symmetry – those could have important implications for the understanding of the matter/anti-matter asymmetry in the Universe.
DUNE will use the most intense muon neutrino and anti-neutrino beams, a set on Near Detectors to characterize them close to the production point and four large Far Detectors.
The LIP group activities are focused on the development of calibration systems for the Far Detector (a 17 kTon Liquid Argon TPC) and testing them at the ProtoDUNE at CERN.
