Continuous loading of ultracold molecular gases to a microwave trap

我们研究了如何利用在谐振腔中增强的微波驻波来控制分子的平移运动。作为第一步，在进行减速和捕获之前，我们已经实现了一个微波分子聚焦器，它的作用就像一个光的透镜。实验中使用了慢速氨束。我们还开发了超导谐振器，大大增强了微波场。我们已经实现了这些谐振器的高质量因子超过10^5。

We have pursued how to control the translational motion of molecules by using a standing wave of microwave enhanced in a resonator. As the first step, before performing deceleration and trap, we have realized a microwave molecular focuser which acts like a lens for light. A slow ammonia beam was used for that experiment. We have also developed superconducting resonators to greatly enhance the microwave field. We have realized a high quality factor of more than 10^5 for those resonators.
