Charge breeding ions for nuclear physics with the PHOENIX ECRIS

At ISOLDE, CERN, an online PHOENIX ECR charge state breeder is being tested for the investigation of the 1+→n+ scenario for the next generation ISOL postaccelerators. As the program of tests reaches an end, the possible physics experiments with multiply charged radioactive ion beams are being investigated. Especially the use of the ECR charge breeder in combination with a high voltage platform would permit an acceleration of the radioactive ions produced at ISOLDE to total energies up to a few MeV. This opens up possibilities for nuclear astrophysics experiments such as various studies of low energy radiative capture reactions. Experiments requiring the implantation of radioactive ions in a substrate at varying depth can also be conceived. This contribution presents the various aspects of the current performances of the PHOENIX ECR charge breeder that could benefit physics applications.
