Since 2001, the SPIRAL I Facility (Système de Production d’Ions Radioactifs en Ligne, version I) located at GANIL in Caen (France) has delivered radioactive ion beams mainly of “light” gaseous elements, from He to Kr. In March 2004, a beam of some pps of 31Ar (15ms) was produced. Very soon, a new target-and-ion-source system (TISS) will be tested for the production of radioactive multi-charged ions of alkaline elements. For making radioactive ion beams of heavier elements, the SPIRAL II project is under study. The proposed technique is to produce heavy fragments by fission of uranium induced by neutrons, themselves produced by a 200kW deuteron beam hitting a carbon converter. The technical studies should be completed by the end of 2004. After a short presentation of results from the operation of SPIRAL I, the design of the SPIRAL II target and ion-source system is presented.
