Description
Multi-step resonance laser ionization has become an essential tool for the production of isobarically pure radioactive ion beams at the Isotope Separator On-Line (ISOL) facilities around the world. A resonant ionization laser ion source (RILIS) had been developed [1] for the former Holifield Radioactive Ion Beam Facility (HRIBF) of Oak Ridge National Laboratory (ORNL). The RILIS employs the widely-used hot-cavity ion source and all-solid-state Ti:Sapphire lasers. The laser system consists of three grating-tuned lasers and individual pump lasers, especially designed for stable and simple operation. The RILIS has been installed at the Injector for Radioactive Ion Species 2 [2], the second ISOL production platform at the former HRIBF, and has successfully provided beams of neutron-rich 78,83-86Ga isotopes for beta decay studies [3]. The features, advantages, limitations, on-line implementation, and performance of the RILIS in off-line and on-line operations will be presented.
