  A cesium atomic fountain clock is under development at Huazhong University of
Science and Technology (HUST) in China. In this paper, we describe the
construction of the entire fountain clock system and report the preliminary
results. A frequency stability of $2.5\times 10^{-13} {\tau}^{-1/2}$ has been
achieved by inter-comparison with a hydrogen maser, and the factors limiting
the frequency stability are also discussed.
