Abstract
We report operation of a microwave frequency standard based on the 12.6 GHz ground-state hyperfine transition in a cloud of laser-cooled /sup 171/Yb/sup +/ ions. The projected performance of this standard (frequency uncertainty /spl les/ 4 /spl times/ 10/sup -15/ and stability 5 /spl times/ 10/sup -14/ /spl tau//sup -1/2/ for a 10 s Ramsey time) is comparable to that of a cesium fountain.
