Virtues and problems of the high C-field Cs beam frequency standard.
The high C-field Cs beam frequency standard is presently a working machine that is undergoing first evaluations. The projected 10(-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.
