摘要:

针对小型化高精度铷原子频标应用需求,设计了体积为11 mL的小型化开槽管微波腔.实验测量了微波腔内微波场的方向因子,结果为0.83.利用该微波腔设计了小型化铷频标物理系统,形成了铷频标桌面系统.测试了系统的短期频率频率稳定度,结果优于2×1012/√τ,远高于一般商用小型化铷原子频标.

Abstract:

A slotted-tube microwave cavity with a volume of 11 mL was designed for miniaturized high-performance rubidium atomic frequency standards (RAFS). The magnetic field orientation factor of the cavity was measured to be 0.83. A miniaturized physics package for RAFS was designed based on the dimensions of the cavity, and a desk prototype of RAFS was built. Short-term frequency stability of the miniaturized RAFS built was measured to be better than 2×1012/√τ, suggesting that the microwave cavity can be utilized for construction of RAFS with small size and high performance.

Key words: rubidium atomic frequency standards (RAFS), slotted-tube microwave cavity, miniature, high performance
