Design of a Hydrogen Maser for Space

E.M. Mattison, R.F.C. Vessot

Abstract:	An atomic hydrogen maser for long-term use in space has been designed and built as part of the Smithsonian Astrophysical Observatory's Hydrogen Maser Clock (HMC) project. We describe features of the maser's mechanical, magnetic, and thermal design that are important to its performance in space. The flight hardware has been tested in a laboratory vacuum chamber. We report measurements of the performance of the maser's control systems.
