Description

The resonance ionization laser ion source (RILIS) has become the most-used ion source type in the ISOL (Iso tope Separator for On-Line) facilities worldwide due to its element selectivity and high ionization efficiency. The hot-cavity type RILIS developed at RAON is based on resonant excitation of atomic transitions by the frequency tuned laser beams which are overlapped temporally and spatially and transported to the 3 mm aperture of the hot-cavity. The RILIS laser system consists of 4 Ti:Sapphire lasers pumped by a 100 W Nd:YAG laser at 10 kHz repetition rate. An additional Nd:YAG laser of 10 W with 10 kHz is also fitted up for off-resonance ionization scheme. For the laser ionization scheme study, the RAON RILIS has been already tested with stable Sn isotopes in the off-line test facility, demonstrating the improved ionization efficiency.
This presentation reports on ongoing Mg and Al ion beam studies for the development of a resonance ionization laser ion source at the IRIS ISOL facility.
