Abstract :
The high C-field Cs beam frequency standard is presently a working machine which is undergoing first accuracy evaluations. The projected 10/sup -14/ accuracy goal is as yet unattained mainly because of inadequate C-field uniformity and stability. An analysis of the projected possible C-field improvements and the consequent uncertainty is here reported.
