The goal for future neutrino facilities is the determination of the [Ue3] mixing and CP violation in neutrino oscillations. This will require precision experiments with a very intense neutrino source. The future experiments such as T2K, NOVA and Double CHOOZ will measure the [Ue3] mixing. In order to explore CP violation, we present a novel method to create a monochromatic neutrino beam based on the recent discovery of nuclei that decay fast through electron capture in a superallowed Gamow-Teller transition. The boost of such radioactive ions will generate an intense monochromatic directional neutrino beam when decaying at high energy in a storage ring with long straight sections. We show that the capacity of such a facility to discover new physics is impressive, so that the principle of energy dependence in the oscillation probability of the suppressed {nu}e {yields} {nu}{mu} channel is operational to separate out the two parameters of the mixing {theta}13 and the CP-violating phase {delta}.
