Preliminary Results From the USNO Atomic Fountain Development Project

Thomas B. Swanson, Eric A. Burt, Christopher R. Ekstrom

Abstract:	Atomic fountain clocks are emerging as an important new technology for the realization of extremely precise passive atomic standards. The U.S. Naval Observatory (USNO) has undertaken a project to develop atomic fountains for eventual incorporation into the USNO Master Clock. We have recently demonstrated short-term stability of 2xI0^-13 at I second with white frequency behavior into the mid I0,’5s in our first cesium R&D device. We report on these results and hope to have frequency measurements relative to internal timescales at the USNO. We also discuss plans for more heavily engineered operational devices and their incorporation into the USNO Master Clock.
