Abstract：
The off-line system of He-jet laser ion source at Tsinghua University was tested and described briefly. Experimental results of direct resonant ionization of Na atoms at the outlet of He-jet of the system by laser were reported. The results show that in-beam ionization of Na atoms at the outlet of the He-jet is practicable. A laser ion source based on such design will possess good Z selectivity, high efficiency, short delay time, and applicability to refractory elements.
