On the accuracy of Cs beam primary frequency standardsA new and much more exact method for evaluation of the velocity distribution in 10 to the 15th power of the frequency of the clock. It seems feasible to improve the accuracy even further with better measurements. The evaluation of the C-field, however, is still limited to a few parts in 10 to the 14th power because of the uncertainties linked to the method used, and this uncertainty remains one of the major limitations of NRC's primary clocks.
