High-Q frequency-temperature compensated solid-nitrogen-cooled resonator-oscillators: first results

摘要

Experimental results for two solid-nitrogen-cooled microwave resonator oscillators are presented. The Allan deviation was measured to be just less than 2x10~(13) for 10s<τ<100s in the dual-mode oscillator and 2-3 x 10~(13) for 1s<τ<6 s in the sapphire-rutile composite design.
