我们描述了一种线性Paul RF离子陷阱的构型。这种陷阱可以存储一长串离子，具有很小的二阶多普勒频移，可以与四极Paul陷阱中的单个离子相媲美。在陷阱中观察到了结晶的俘获离子串以及更复杂的结构。本文报道了用微波-光学双共振光谱技术观测到的Hg-199(+)的40.5 GHz基态超精细间隔，并讨论了基于俘获离子弦的微波频率标准的前景。
We describe a configuration for a linear Paul rf ion trap. This trap can store a long string of ions with a small second-order Doppler shift, comparable to that achieved with a single ion in a quadrupole Paul trap. Crystallized strings of trapped ions, as well as more complicated structures, have been observed in the trap. We report an observation of the 40.5-GHz ground-state hyperfine interval of Hg-199(+) by microwave-optical double-resonance spectroscopy and discuss prospects for a microwave frequency standard based on a trapped string of ions.
