Techniques developed during previous studies of the ground-state hyperfine resonance of hydrogen atoms intermittently adsorbed on molecular hydrogen surfaces were used to develop a cryogenic atomic-hydrogen maser using a 5 K state-selected H-atom beam and solid-neon storage surfaces near 10 K temperature. The physical parameters affecting the use of such a device for frequency metrology and precision measurements of atomic parameters were determined.
