In this paper, the loss rate in a cold rubidium-87 atom cloud was measured in a magneto-optical trap （MOT） and during its free flight. The residual gas pressure was analyzed by a residual gas analyzer, and the pressure distribution in a vacuum chamber was numerically calculated by the angular coefficient method. The decay factor, which describes the decay behavior of cold atoms due to residual gas collisions during a free flight, was calculated. It was found that the decay factor agrees well with theoretical predictions under various vacuum conditions.展开更多

The space-qualified ST Rb SCAC is composed of the physical package, the optical bench, the microwave synthesizer and the control electronics. After the system is integrated, about 108 ST Rb cold atoms are captured by magneto-optical trap. The linewidth of the Ramsey fringe is about lO Hz for the free evolution time of 50ms on the ground, and the signM-to-noise ratio is measured to be larger than 300. We demonstrate a good medium-term fractional frequency stability of 1.5×10^-14@1000s in the closed-loop operation on the ground. The main effects of the noise on the stability are a/so presented, and the optimized operating parameter is analyzed for the operation of SCAC in the microgravity environment.展开更多
