  Beta Beams are designed to produce pure (anti)electron neutrino beams and
could be an elegant and powerful option for the search of leptonic CP violating
processes. In this paper will be quantified the physics reach of a CERN based
Beta Beam and of a Super Beam - Beta Beam combination. The CP phase $\delta$
sensitivity results to be comparable to a Neutrino Factory for
$\sin^2{\theta_{13}}$ values greater than $10^{-4}$.
