Abstract

At the National Research Council Canada we are currently performing the first accuracy evaluation of our newly developed caesium fountain clock, NRC-FCs2. This primary frequency standard operates with a short term stability of \sigma-{\mathbf{y}}(\tau)=1.1\ \mathbf{x}\ 10^{-13}\tau^{-1/2} and, upon full evaluation, we expect to achieve a type B uncertainty in fractional frequency below 5\ \mathbf{x}\ 10^{-16}. We will discuss the current status of the evaluation, including several evaluated shifts, as well as the outstanding systematics yet to be fully characterized.
