摘要

我们提出了一种基于二维磁光阱的冷铊原子源的设计，并对其操作进行了数值模拟。确定了冷却辐射和磁场的最佳参数；结果表明，对于50mW的总辐射功率和800K的原子炉温度，所提出的配置可以提供每秒4×108个冷原子的通量，并且随着炉温度的升高，通量可以达到~1011个原子/s。这种源可以用于建立频率标准，也可以用于量子模拟器和玻色-爱因斯坦凝聚体的实验。

Two-Dimensional Magneto-optical Trap for Producing a Flux of Cold Thulium Atoms

We propose a design of a source of cold thulium atoms based on a 2D magneto-optical trap and perform numerical simulation of its operation. Optimal parameters of cooling radiation and the magnetic field are determined; it is shown that for a total radiation power of 50 mW and an atomic oven temperature of 800 K, the proposed configuration can provide a flux of 4 × 10⁸ cold atoms per second, and with an increase of the oven temperature, the flux can reach ~ 10¹¹ atom/s. Such a source can be used for building frequency standards as well as in experiments with quantum simulators and the Bose–Einstein condensate.
