Abstract

Development of space passive hydrogen maser in Shanghai Astronomical Observatory was briefly reported. Main techniques, including novel cavity-bulb assembly, absorption pump, nickel tube purifier and time-separated control scheme of electronics package, were described. By using the techniques, performances and life time of the prototype were improved. Engineering modification is under way.
