The ion source combining laser ablation of solid targets in helium gas and an RF ion guide system with an RF carpet was constructed for a reference measurement of isotope shifts. It is important for performing planned collinear laser spectroscopy of RI beams from the SLOWRI facility at RIKEN, especially for medium-mass nuclei of refractory elements. They are difficult to produce via the ISOL method owing to the chemical properties of the elements. The laser-ablated ions of Ni, Zr, Ag, Ta, W, and Ba were transported by the ion guide and mass spectra consistent with the natural abundance were successfully observed corresponding to 10⁵–10⁷ ions per laser pulse.

构建了将氦气中的固体靶材激光烧蚀与带有RF地毯的RF离子引导系统相结合的离子源，用于同位素位移的参考测量。对于RIKEN SLOWRI工厂的RI光束进行计划共线激光光谱分析非常重要，特别是对于难熔元素的中等质量核。由于元素的化学性质，它们很难通过ISOL方法生产。Ni，Zr，Ag，Ta，W和Ba的激光烧蚀离子通过离子导向器传输，成功观察到与自然丰度相符的质谱，对应于每个激光脉冲10 ⁵ –10 ⁷离子。
