【摘要】 氢微波激射器（氢脉泽）采用原子储存泡对氢原子进行囚禁,在低损耗谐振腔内形成稳定的自持振荡.本文采用具备低腔频温度系数的介质加载谐振腔替换传统的腔-泡结构,实现了氢脉泽的小型化;并分析了这种小型化方案对频率稳定度和准确度的影响.原子储存时间设计值为0.4 s,闭环后的频率稳定度为5.6×10^-15/（1 000 s）,与储存时间设计结果相吻合.更多还原

【Abstract】 A hydrogen maser confines hydrogen atoms in the storage bulb and produces self-sustained oscillation in a low-loss resonance cavity. In this work, a miniaturized hydrogen maser was designed and fabricated utilizing a dielectric loaded cavity having a low frequency-temperature coefficient. The frequency stability and accuracy of the hydrogen maser were analyzed. The experimentally measured atomic storage time of the hydrogen maser was 0.4 s, and the frequency stability 5.6×10^-15/（1 000 s）, agreeing with the design.更多还原
