  • Abstract
    Over more then 30 years, Shanghai Astronomical Observatory has developed three generations of hydrogen masers, 6 laboratory models and more than 40 engineering units of active hydrogen masers as well as a compact passive hydrogen maser. They have been used in several fields, including one which is in Australia. This paper describes their design features, applied performance specifications and their applications.
