| 摘 要： | 简要介绍了建立在清华大学的氦喷嘴激光离子源离线系统.并给出了在氦喷嘴出口处激光直接共振电离喷束中的钠原子的实验结果.此结果表明,在氦喷嘴出口处,用激光在束电离钠原子是可行的.由此出发可设计具有Z选择性、效率高、可测同位素寿命下限低又能适用于高温难熔元素的激光离子源.

| 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. |
