We have compared the frequency of a room- temperature cesium-fountain primary frequency standard with that of a cryogenic (~80K) cesium fountain. This comparison yields a measurement of the blackbody frequency shift of the room-temperature fountain.

Abstract

We have compared the frequency of a room- temperature cesium-fountain primary frequency standard with that of a cryogenic (~80K) cesium fountain. This comparison yields a measurement of the blackbody frequency shift of the room-temperature fountain.
