Abstract:
The off-line test setup of the laser ion source built in Tsinghua University is described briefly. The experimental result of laser resonant ionizing Na atoms carried by He gas at the outlet of He-jet are presented. The results indicate that the in-beam ionization of Na atom is viable. Based on these results, vve can design a laser ion source that has high Z selectivity,-high efficiency, low limits of lifetime for isotopes being studied, and is applicable for studying refractory elements.
