Archivio Istituzionale della RicercaIn this paper we present the current status in the realization of a new generation of high accuracy frequency standards at INRIM, whose relative frequency uncertainty is expected to achieve and possibly pass the 10-16 range. Currently we are developing a nitrogen cooled cryogenic Cs fountain and a dipole trap neutral Yb optical clock. This development will allow us to make an absolute measurement of the Yb clock frequency against a primary frequency reference in the low 10-16 range.

Abstract
In this paper we present the current status in the realization of a new generation of high accuracy frequency standards at INRIM, whose relative frequency uncertainty is expected to achieve and possibly pass the 10-16 range. Currently we are developing a nitrogen cooled cryogenic Cs fountain and a dipole trap neutral Yb optical clock. This development will allow us to make an absolute measurement of the Yb clock frequency against a primary frequency reference in the low 10-16 range.
