摘要:

我们提出了一种高通量的冷镱原子源,它是坚固的,重量轻,维护成本低。我们的装置提供$10^9$原子/s到一个三维磁光阱,而不需要水冷却或高电流电源。我们实现这一点,采用塞曼慢和二维磁光阱完全基于永磁体在Halbach配置。这种策略最大限度地减少了机械复杂性、杂散磁场和发热,同时几乎不需要维护,使其适用于寻求最小化电力消耗的嵌入式系统和大规模实验,以降低其子系统的复杂性。

英文摘要:

We present a high-flux source of cold ytterbium atoms that is robust, lightweight and low-maintenance. Our apparatus delivers $10^9$ atoms/s into a 3D magneto-optical trap without requiring water-cooling or high current power supplies. We achieve this by employing a Zeeman slower and a 2D magneto-optical trap fully based on permanent magnets in Halbach configurations. This strategy minimizes mechanical complexity, stray magnetic fields, and heat production while requiring little to no maintenance, making it applicable to both embedded systems that seek to minimize electrical power consumption, and large scale experiments to reduce the complexity of their subsystems.
