Abstract :
National Institute of Information Communications Technology (NICT) has been developing a Cesium atomic fountain primary frequency standard. In order to achieve the high stability as the frequency standard, we have made efforts to improve the signal to noise (SN) ratio of the signal. The frequency stability is 2 10-12tau1/2 presently. This report presents the current status of the development of NICT atomic fountain.
