我们讨论了由长谷川和博林格[《物理评论A》72，043403(2005)]提出的旋转射频(rrf)阱的实验实现。与传统的线性射频(lrf)保罗阱相比，rrf阱更类似于流行的保罗阱机械演示。在具有实际的、非理想电极几何形状的离子阱中，rrf阱对有效势中的角度变化进行平均。与lrf阱相比，这种平均提供了更均匀的限制，并在相同限制强度下减少了离子损失。这一特性使得rrf阱配置有利于精密计量应用，如电子电偶极矩(eEDM)测量。
英文摘要
We discuss the experimental realization of the rotating radio-frequency (rrf) trap, proposed by Hasegawa and Bollinger [Phys. Rev. A 72, 043403 (2005)]. Compared to a traditional linear rf (lrf) Paul trap, the rrf trap is a closer analogy to the popular mechanical lecture demonstration for a Paul trap. In an ion trap with reslistic, non-ideal electrode geometry, the rrf trap averages over angular variations in the effective potential. This averaging provides more uniform confinement and reduces ion loss at equal confinement strength compared with the lrf trap. This feature makes the rrf trap configuration advantageous for precision metrology application, such as electron electric dipole moment (eEDM) measurements.
