High intensity neutrino oscillation facilities in Europe
The EUROnu project has studied three possible options for future, high intensity neutrino oscillation facilities in Europe. The first is a Super Beam, in which the neutrinos come from the decay of pions created by bombarding targets with a 4 MW proton beam from the CERN High Power Superconducting Proton Linac. The far detector for this facility is the 500 kt MEMPHYS water Cherenkov, located in the Fréjus tunnel. The second facility is the Neutrino Factory, in which the neutrinos come from the decay of μ+ and μ− beams in a storage ring. The far detector in this case is a 100 kt magnetized iron neutrino detector at a baseline of 2000 km. The third option is a Beta Beam, in which the neutrinos come from the decay of beta emitting isotopes, in particular He6 and Ne18, also stored in a ring. The far detector is also the MEMPHYS detector in the Fréjus tunnel. EUROnu has undertaken conceptual designs of these facilities and studied the performance of the detectors. Based on this, it has determined the physics reach of each facility, in particular for the measurement of CP violation in the lepton sector, and estimated the cost of construction. These have demonstrated that the best facility to build is the Neutrino Factory. However, if a powerful proton driver is constructed for another purpose or if the MEMPHYS detector is built for astroparticle physics, the Super Beam also becomes very attractive

PANDORA, a new facility for interdisciplinary in-plasma physics
PANDORA, Plasmas for Astrophysics, Nuclear Decays Observation and Radiation
for Archaeometry, is planned as a new facility based on a state-of-the-art
plasma trap confining energetic plasma for performing interdisciplinary
research in the fields of Nuclear Astrophysics, Astrophysics, Plasma Physics
and Applications in Material Science and Archaeometry: the plasmas become the
environment for measuring nuclear decays rates in stellar-like condition (such
as 7Be decay and beta-decay involved in s-process nucleosynthesis), especially
as a function of the ionization state of the plasma ions. These studies are of
paramount importance for addressing several astrophysical issues in both
stellar and primordial nucleosynthesis environment (e.g. determination of solar
neutrino flux and 7Li Cosmological Problem), moreover the confined energetic
plasma will be a unique light source for high performance stellar spectroscopy
measurements in the visible, UV and X-ray domains, offering advancements in
observational astronomy. As to magnetic fields, the experimental validation of
theoretical first and second order Land\'e factors will drive the layout of
next generation polarimetric units for the high resolution spectrograph of the
future giant telescopes. In PANDORA new plasma heating methods will be
explored, that will push forward the ion beam output, in terms of extracted
intensity and charge states. More, advanced and optimized injection methods of
ions in an ECR plasma will be experimented, with the aim at optimizing its
capture efficiency. This will be applied to the ECR-based Charge Breeding
technique, that will improve the performances of the SPES ISOL-facility
currently installed at Laboratori Nazionali di Legnaro-INFN. Finally, PANDORA
will be suitable for energy conversion, making the plasma as a source of
electromagnetic radiation, for applications in Material Science and
Archaeometry
