Abstract
This article describes a long-life hydrogen gas discharge source for the JPL hydrogen maser. The lifetime of this source has been extended from approximately 6 months to 2 years or more by changing the geometry of the RF power coupling mechanism. Other improvements over the older type source are: (1) the gas discharge may be started without increasing hydrogen pressure, and (2) an acceptable impedance match to the RF power generator can be achieved over a broader range of operating hydrogen pressures.
