We describe a method that allows accumulation in a Paul trap of a large number of ions obtained from multiple laser ablation pulses, and therefore solving the problem of a single pulse that usualy gives rise to final trapping of too few ions. The proposed method of the cumulative trap loading was based on interaction with a buffer gas that provided a friction force. The method was applied to triply charged thorium ions and trapped a total of 10⁶ ions. Numerical analysis of the ion motion allowed the experimental parameters to be optimized for the most effective implementation of the technique.

激光烧蚀buffer气中target靶的离子阱累积载荷

我们描述了一种方法，该方法允许在Paul阱中积累从多个激光烧蚀脉冲获得的大量离子，因此解决了通常导致最终捕获太少离子的单个脉冲的问题。所提出的累积捕集阱负荷的方法是基于与提供摩擦力的缓冲气体的相互作用。该方法应用于三重带电的or离子，总共捕获了10 ^6个离子。离子运动的数值分析使实验参数得以最优化，以最有效地实施该技术。
