Caption
Schematic of Fountain Clock Juggling Cesium Atoms. Two clouds of cesium atoms are tossed upward with a short time delay so that they collide after passing through the microwave cavity (silver) on the way up and before they return down through the cavity. The microwaves in the cavity excite and probe the atoms, resulting in an atomic fountain clock.
