Description
SPIRAL1 (Système de Production d’Ions Radioactifs Accélérés en Ligne phase 1) is an ISOL system installed at GANIL (Grand Accélérateur National d’Ions Lourds) at CAEN/France. Since 2001, it uses a large variety of primary beams, from C to U, at energies up to 95 MeV/u to produce low energy or post-accelerated Radioactive Ion Beams (RIB). The possibilities of primary beam and target coupling allow SPIRAL1 [1] to use a large variety of nuclear reactions, which eases access to regions of the nuclide chart often difficult to explore with ISOL installations.
Within this framework, the TULIP project [2] aims to produce original RIBs in the very exotic neutron-deficient region of the nuclide chart. The approach consists of favouring the atom-to-ion transformation efficiency for short-lived isotopes rather than the in-target production rate. The Target Ion Source System (TISS) design was guided by the improvement of the efficiency of each process involved, i.e. in-target production, diffusion of atoms out of the stopping material, effusion and ionisation.
A first TISS prototype was designed to produce ions of neutron deficient isotopes of Rb. Once the proof of principle shown [3,4], the TISS was coupled to a FEBIAD [5] ion source to reach the final aim of the TULIP project, namely the production of metallic ions near 100Sn.
The status of this project and the first results will be presented.
