一种低温度敏感性铷频标物理部分研究

Research On Package Physics of Rubidium Frequency Standard with Low Temperature Sensitivity

物理部分是原子频标的核心部件,对温度变化比较敏感。因此,温度敏感性是铷频标稳定度提高的一个重要限制因素。以一种改进型铷频标物理部分为研究对象,在分析温度波动对铷频标稳定度影响的基础上,提出了改进铷频标物理部分温度敏感性的措施。通过试验验证,这些措施能够有效地降低铷频标物理部分温度系数。

The physics package is the core of atomic frequency standard,and temperature sensitivity is the most signification limitation to improve the frequency stability of rubidium frequency standard（RFS）.In this paper,researched on the basis of analysis of the affection of temperature fluctuation to the frequency stability of RFS,a kind of physics package was designed and its physical properties were studied to validate the reduction of its temperature sensitivity.
