Abstract

In this paper, a unique physics package using slotted-tube cavity for rubidium atomic frequency standard has been described, including its structure, characteristics and performances. Due to the advantages of high cavity Q factor, large microwave filling factor, stable light intensity and so on, the physics package has obtained a high signal-to-noise ratio. The test results suggest that RAFS using this physics package has achieved an excellent short-term frequency stability of 1.2E-12 / tau^frac12 (1 s les tau les 100 s).
