Neutrino Projects 18 -3 -2016

Mandate “Rapid progress in neutrino oscillation physics, with significant European involvement, has established a strong scientific case for a long-baseline neutrino programme exploring CP violation and the mass hierarchy in the neutrino sector. CERN should develop a neutrino program to pave the way for a substantial European role in future long-baseline experiments. Europe should explore the possibility of major participation in leading long-baseline neutrino projects in the US and Japan. ”

Large prototyping activities for LBNF/DUNE CERN provides Civil Engineering and Infrastructure, …. . investment for the future also for other applications

Single phase proto. DUNE Single phase LAr TPC Operational in 2017, SPS calibration beams in 2018 Active volume ~ 7 x 7 x 6 m 3

Double phase proto. DUNE Double phase LAr TPC Operational in 2017, SPS calibration beams in 2018 Active volume 6 x 6 x 6 m 3

Large prototyping activities for LBNF/DUNE To learn about: LAr - Large cryostats of a new generation (LNG carrier technology) ~1000 tons - Very pure cryogenics at the ppt level, large plants - New technologies for LAr Time Proportion Chamber technology (single phase, double phase) - Large data sets (similar to LHC-heavy Ions) - New photon detector technologies (large area Si. PM arrays? ), interesting for other applications (space, dark matter, telescopes, …) - Large size detector engineering integration - Automatic patter recognition (new in the community !) - Team/Collaboration building in the Neutrino Community At CERN ~ 300 Collaborators involved, ~100 from USA
