Abstract
We demonstrate a Rb fountain clock which has a small cold collision shift that is cancelled by detuning the microwave cavity. We also demonstrate a juggling Rb clock and propose a novel quantum atom-optics precision scattering measurement for a juggling atomic clock. Finally we describe the design concept for RACE, a microgravity Rb clock for the ISS.
