Abstract:	NICT in Japan is developing a cesium atomic fountain NICT-CsF2 with the goal of operation at the 10^-16 level. It is the second atomic fountain to be constructed at NICT and it shares many features with the first fountain NICT-CsF1. A narrow Ramsey signal of less than 1Hz has been observed and the short-term stability is currently 3×10^-13/t 1/2. An evaluation of systematic frequency shifts and their uncertainties has commenced and preliminary results are presented here.
