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.
最近，一种基于宏观三维行进式静电阱工作的中性极性分子减速器已被提出[A. 奥斯特瓦尔德、S. A. 米克、G. 哈默、H. 哈克和G. 迈耶，《物理评论A》81, 051401 (2010)]。在本文中，对该减速器进行了完整描述，重点在于电子学和机械设计。展示了表明被引导分子横向速度分布的实验结果，并与轨迹模拟结果进行了比较。通过比较来自(13)CO和(12)CO的减速信号以及模拟信号，对非绝热损失进行了评估。
