摘要:

我们提出了我们的铁芯电磁体的设计BEC,以及如何解决这种技术所提出的具体实验问题。在介绍了实验装置后,我们解决了塞曼效应非线性时失控蒸发冷却的中断问题。我们提出的方法来规避这个问题,使用多个射频频率,交感冷却,并显示这些高磁场(腔耦合,高约束)的一些应用。

英文摘要:

We present the design of our iron-core electromagnet for BEC, and how to solve the specific experimental problems raised by this technique. After presenting the experimental set-up, we address the interruption of runaway evaporative cooling when the Zeeman effect is not linear. We present the ways to circumvent this problem, use of multiple RF frequencies, sympathetic cooling and show some applications of these high magnetic fields (cavity coupling, high confinement).
