Continuous loading of ultracold molecular gases to a microwave trap

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.
