我们建议使用超导微波腔的冷极性分子束的聚焦和减速。具有高品质因数的超导腔在极性分子中产生大的交流斯塔克位移，这使我们能够有效地控制分子运动。我们的讨论是基于一个原型腔的实验表征：一个铅锡涂层的圆柱形铜腔，它的品质因数为106，并容忍几瓦的输入功率。这样的微波装置提供了一种强大的方式来控制分子，不仅在低场寻求状态，而且在高场寻求状态，如地面旋转状态。
We propose the use of superconducting microwave cavities for the focusing and deceleration of cold polar molecular beams. A superconducting cavity with a high quality factor produces a large ac Stark shift in polar molecules, which allow us to efficiently control molecular motion. Our discussion is based on the experimental characterization of a prototype cavity: a lead–tin-coated cylindrical copper cavity, which has a quality factor of 106and tolerates several watts of input power. Such a microwave device provides a powerful way to control molecules not only in low-field-seeking states, but also in high-field-seeking states such as the ground rotational state.
