The production and generation of radioactive beams at Louvain-la-Neuve

Recent development work on various aspects of the generation of radioactive ion beams at Louvain-la-Neuve is reported. The performances of CYCLONE44, the new isochronous cyclotron designed for the combined acceleration and isobaric separation of RIB at low energy are discussed. The results obtained with a new target dedicated to the production of /sup 15/O, and able to stand 9 kW of 30 MeV proton beam power are presented. The present status of the research and development efforts aiming at the acceleration of an intense /sup 7/Be beam is given.Anglai

Commissioning of CYCLONE44, a cyclotron for low energy radioactive beams

CYCLONE44 is a compact cyclotron dedicated to the acceleration and isobaric separation of unstable ions. It will cover an energy domain between 0.2 and 0.8 MeV per nucleon, and will be used for experiments in nuclear astrophysics. The design features of the machine, which has to combine a high acceleration efficiency and a high mass resolving power in order to provide pure radioactive beams in the presence of intense isobaric contaminants, is presented. The status of CYCLONE44, which has accelerated its first stable beam a few days before the conference, is reported.Anglai
