Since its invention in the 1950’s, the “Isotope Separation On Line” (ISOL) method has actively participated to the development of nuclear science by providing numerous facilities with a powerful technique of Radioactive Ion Beams (RIB) production. It was more recently associated to techniques of RIB manipulation: ion cooling and trapping, charge state breeding, mass and charge state separation techniques are fruitful ingredients for extending the physics potentials of the facilities. Today, the development of such techniques of RIB production and manipulation occupies a central place in the upgrade project of major nuclear facilities such as HIE-ISOLDE at CERN, or SPIRAL2 at GANIL. These upgrades are important milestones towards the ultimate ISOL facility EURISOL. Beyond the domain of nuclear science, neutrino physics could benefit from the efforts done for developing high intensity RIB’s: Beta-Beam is a concept of long baseline experiment for the measurement of neutrino oscillations, using the post-acceleration and storage of beta-emitters at large Lorentzian gamma (100) for producing pure neutrino and anti-neutrino beams. The sensitivity of Beta-Beam to 13 and to the CP violating angle is competitive with other projects of long baseline experiments such as Superbeam and neutrino factories, provided that enough radioactive nuclides are produced and accelerated. In this seminar, selected aspects of the RIB production and manipulation will be reviewed, in regard of the scientific objectives of the GANIL upgrade projects, EURISOL and Beta-Beam.
