The Development and Future of Hydrogen Maser Clock Technology

由氢脉泽原理对原子频率标准目前的发展进行了分析。对主动和被动氢脉泽限制频率稳定度的基本不稳定因素进行了分析。描述确保主动和被动氢脉泽高短期和长期频率稳定的设计方法。现在,主动氢脉泽指标可达到1.10-13/s和3.5.10-16/d,被动氢脉泽指标可达到4.10-13/s和2.5.10-15/d。还讨论了氢脉泽指标的进一步改善。

The analysis of current development of atomic frequency standards is given on the basis of hydrogen masers.Contains the analysis of basic destabilizing factors limiting frequency stability of active and passive hydrogen masers.Describes design solutions of active and passive hydrogen masers insuring high short-term and long-term frequency stability.Today,the values of ~1·10-13 per one second and 3.5·10-16 per day for active hydrogen maser,and of 4·10-13 per one second and 2.5·10-15 per day for passive hydrogen maser are achieved.The further improvements of performance specifications of hydrogen masers are discussed.
