论文摘要
我们报告了基于二维磁光陷阱（MOT）的盆地（SR）冷原子源的设计和表征，该原子源是从分配器的原子射流中直接加载的。我们通过测量三维MOT的加载速率来表征源的原子通量。我们发现每秒最高$ 10^{8} $原子的加载率。该设置紧凑，易于构造，并且功耗低。它解决了降低SR冷束源复杂性的长期挑战，这与基于Ultracold Sr的光原子时钟以及量子模拟和计算设备有关。
We report on the design and characterization of a cold atom source for strontium (Sr) based on a two-dimensional magneto-optical trap (MOT) that is directly loaded from the atom jet of a dispenser. We characterize the atom flux of the source by measuring the loading rate of a three-dimensional MOT. We find loading rates of up to $10^{8}$ atoms per second. The setup is compact, easy to construct, and has low power consumption. It addresses the long standing challenge of reducing the complexity of cold beam sources for Sr, which is relevant for optical atomic clocks and quantum simulation and computing devices based on ultracold Sr.
