Design of the Atomic Storage Time of a Miniaturized Hydrogen Maser

doi:10.11938/cjmr20192712

Abstract

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.

Key words: hydrogen maser, atomic storage time, relaxation time, frequency stability
