We demonstrate a convenient experimental method, that facilitates faster and more accurate evaluation of the distributed cavity phase, a leading systematic effect in atomic fountain clocks. We expand on earlier work by Nemitz et al., which showed tha

Following a refined NPL design, we have constructed several Cs fountain primary frequency standards for use in different metrology laboratories. In this paper we describe the design of these new systems and present measurements of their performance.
