最近，提出了一种中性极性分子减速器，其基于宏观、三维、移动静电陷阱进行操作[A. Osterwalder、S.A. Meek、G. Hammer、H. Haak 和 G. Meijer，物理学家。修订版 A 81, 051401 (2010)]。在本文中，对该减速器进行了完整的描述，重点是电子和机械设计。实验结果显示了引导分子的横向速度分布，并与轨迹模拟进行了比较。通过将 (13)CO 的减速信号与 (12)CO 的减速信号以及模拟信号进行比较来评估非绝热损失。
Recently, a decelerator for neutral polar molecules has been presented that operates on the basis of macroscopic, three-dimensional, traveling electrostatic traps [A. Osterwalder, S. A. Meek, G. Hammer, H. Haak, and G. Meijer, Phys. Rev. A 81, 051401 (2010)]. In the present paper, a complete description of this decelerator is given, with emphasis on the electronics and the mechanical design. Experimental results showing the transverse velocity distributions of guided molecules are shown and compared to trajectory simulations. An assessment of non-adiabatic losses is made by comparing the deceleration signals from (13)CO with those from (12)CO and with simulated signals.
