An important remaining issue in the field of cold molecules is a general technique to manipulate the motion of polar molecules in high-field-seeking states, which is crucial for the investigation of molecules in their ground states and of all large and more complex molecules. In contrast to the already demonstrated and experimentally rather challenging alternating gradient methods, we exploit the interaction of polar molecules with electromagnetic radiation in a microwave cavity.
Based on the concept of our microwave lens  we have developed a decelerator for polar molecules, that allows motion control in 3D. We will present a detailed characterisation of the microwave decelerator, e.g. its phase-space acceptance, and discuss prospects for future experiments.
