优化自旋翻转塞曼减速器
Optimizing a spin-flip Zeeman slower
摘要:
本文介绍了一种用于钠玻色-爱因斯坦凝聚体装置的快速反馈控制自旋翻转塞曼慢化器的设计。我们还演示了如何缓慢的效率强烈依赖于其内在参数,并比较这些观察与一些理论模型。我们的研究结果导致一个简单的三步程序设计一个最佳的塞曼慢中性原子,特别是那些原子物种具有高的初始速度,如钠和锂原子。
英文摘要:
We present a design of a spin-flip Zeeman slower controlled by a fast feedback circuit for a sodium Bose-Einstein condensate apparatus. We also demonstrate how the efficiency of the slower strongly depends on its intrinsic parameters, and compare these observations with a few theoretical models. Our findings lead to a simple three-step procedure of designing an optimal Zeeman slower for neutral atoms, especially for those atomic species with high initial velocities, such as sodium and lithium atoms.
