Evaluation of the Cs atomic fountain frequency standard at NMIJ/AIST

We have developed the first cesium atomic fountain frequency standard (JF-1) at National Metrology Institute of Japan. The accuracy evaluation is in progress and the uncertainty of the JF-1 is currently estimated to be 1.4/spl times/10/sup -15/.
