Status of the future SPIRAL2 Resonance Ionization Laser Ion Source GISELE — •Fabian Schneider1, Jose Luis Henares2, Tobias Kron1, Nathalie Lecesne2, Renan Leroy2, Benoit Osmond2, Marica Sjödin2, and Klaus Wendt1 — 1Institut für Physik, Universität Mainz — 2GANIL, Caen, France
Resonance Ionization Spectroscopy is a most powerful tool for efficient and selective production of ion beams in particular useful at on-line isotope breeders. For this purpose the future upgrade S3 (Super Separator Spectrometer) of the SPIRAL2 accelerator at GANIL (Caen, France) includes a gas cell at its fission target. Therein high resolution RIS on short lived isotopes will be performed, addressing either the in-cell or in-jet technology. The corresponding Resonance Ionization Laser Ion Source project GISELE is furthermore designed to produce strong and pure radioisotope beams for experiments at the future hot cavitiy unit of SPIRAL2. Its laser system will combine sets of tunable high-repetition rate pulsed dye as well as titanium:sapphire lasers.
Currently, off-line preparation studies are performed with the titanium:sapphire lasers for the day 1 requested beams of Zinc and Tin. A suitable excitation scheme was developed for Zinc and the ionization efficiency was determined. For Tin three known ionization schemes, a 3-step and two widely identical 2-step schemes, were tested and compared with published results from other facilities.
