Abstract：The Ramsey fringes with a linewidth of 45 Hz and a signal-to-noise ratio of 120 are demonstrated for a integrating sphere atom clock. The cycle time of the atom clock is reduced to 80 ms with the help of a pulsed cooling method. This result indicates that the short-term stability of the clock is in the order of 10?12.
