Cavity-modulation tuning system maintains resonance of hydrogen-maser cavity automatically, stabilizing maser frequency, without introducing undesirable frequency modulation. System tunes maser cavity rapidly by modulating one of physical characteristics of cavity affecting resonant frequency. Frequency-controlling components of tuning system placed at maser cavity, within maser vacuum. Thermal environment well controlled, and device insensitive to driving signal. Features contribute to stability of maser frequency.
