摘要:

我们展示了一种离子穿梭技术,通过将射频阱中的离子平移通过磁光原子阱来高分辨率控制原子-离子碰撞能量。该技术的实验和数值模拟表明,与实验结果表明,从$0.05-1$ K的离子动能控制与$\sim10$的分数分辨率和模拟表明,动能控制高达$120$ K的最大预测分辨率为$\sim100$是可能的,提供了数量级的改进,大多数替代技术。最后,我们使用这种技术进行了一个原理验证化学实验,并概述了该方法在未来如何改进并应用于分子离子化学的研究。

英文摘要:

We demonstrate an ion shuttling technique for high-resolution control of atom-ion collision energy by translating an ion held within a radio-frequency trap through a magneto-optical atom trap. The technique is demonstrated both experimentally and through numerical simulations, with the experimental results indicating control of ion kinetic energies from $0.05-1$ K with a fractional resolution of $\sim10$ and the simulations demonstrating that kinetic energy control up to $120$ K with a maximum predicted resolution of $\sim100$ is possible, offering order-of-magnitude improvements over most alternative techniques. Lastly, we perform a proof-of-principle chemistry experiment using this technique and outline how the method may be refined in the future and applied to the study of molecular ion chemistry.
