Abstract
The Resonance Ionization Laser Ion Source (RILIS) system has been developed for the future on-line laser ion source for a new heavy ion accelerator, RAON, in Korea. A tunable laser system consisting of four Ti:Sapphire lasers pumped by a Nd:YAG laser has been set up for the application in the RILIS laser ion source development in the ISOL facility of the Rare Isotope Science Project (RISP)/IBS. As a milestone of extraction of rare isotopes produced through uranium fission, double magic nucleus of 132Sn is our first target. Three step resonance ionization schemes with four laser wavelengths, at 286 nm, 301 nm, 811 nm and 823 nm, have been investigated for Sn. In this paper, we present the recent results and the current status of the hot-cavity type laser ion source development in the off-line ion source test facility of RISP, including measurements of ionization efficiency and mass resolving power.
