| Popis: | We present the current status of the atomic fountain clock KRISS-F1 under development at KRISS. An ultrastable cryogenic sapphire oscillator (CSO) is used as a local oscillator of the fountain. The short-term stability measured with the CSO reaches $3.2\times 10^{-14}$ at an averaging time of 1 s. The systematic uncertainty of the fountain is expected to reach low 10–16level. The evaluation of the distributed cavity phase shift and its uncertainty is currently underway. |
