AbstractThe Dick effect is an important factor limiting the frequency stability of sequentially-operating atomic frequency standards. Here we study the impact of the Dick effect in the integrating sphere cold atom clock (ISCAC). To reduce the impact of the Dick effect, a 5MHz local oscillator with ultra-low phase noise is selected and a new microwave synthesizer is built in-house. Consequently, the phase noise of microwave signal is optimized. The contribution of the Dick effect is reduced to 2.5x10(-13) tau(-1/2) (tau is the integrating time). The frequency stability of 4.6x10(-13) tau-(1/2) is achieved. The development of this optimization can promote the space applications of the compact ISCAC.
