Abstract

In this paper we consider a Beta Beam setup that tries to leverage at most existing European facilities: i.e. a setup that takes advantage of facilities at CERN to boost high-Q ions (8Li and 8B) aiming at a far detector located at L=732 km in the Gran Sasso Underground Laboratory. The average neutrino energy for 8Li and 8B ions boosted at γ∼100 is in the range E ν ∈[1,2] GeV, high enough to use a large iron detector of the MINOS type at the far site. We perform, then, a study of the neutrino and antineutrino fluxes needed to measure a CP-violating phase δ in a significant part of the parameter space. In particular, for θ 13≥3°, if an antineutrino flux of 3×1019 useful 8Li decays per year is achievable, we find that δ can be measured in 60% of the parameter space with 3×1018 useful 8B decays per year.
