dc.description.abstractThis paper reports implementation and operation of a frequency synthesizer based on a cryocooled cryogenic Sapphire oscillator (cryoCSO) for the Cesium atomic fountain clock developing at KRISS, KRISS-Fl(Cs). With use of this highly stable local oscillator, the short-term stability of KRISS-F1(Cs) was greatly improved and reaches the quantum projection noise limit, resulting in the measured lowest Allan deviation of 2.6×10-14. In addition, the long-term drift (4.8×10-14/day) of the cryoCSO could be compensated and reach below 5×10-16/day as low as state-of-the-art active hydrogen masers.-
