Description
The next round of long-baseline neutrino oscillations measurements, currently supported by a joint European/USA effort within the LBNF-DUNE project, is going to address an ambitious physics program including the assessment of the neutrino mass hierarchy and the search for CP violation in the neutrino sector. The achievement of these goals implies as well strong experimental challenges like the construction of very massive and accurate neutrino detectors, such as liquid argon time projection chambers for a total active mass of 40 kton. A new liquid argon detector technology, based on the dual-phase charge readout, has been intensively developed during the last ten years with the explicit goal of making possible the construction of very large and better performing neutrino detectors. This technology is now being implemented at CERN in a detector of 6x6x6 m3 active volume which will be exposed in 2018 to beams of charged particles and which will also represent a full engineering test of the design of 10kton modules for the DUNE experiment.
