A very high stability sapphire loaded superconducting cavity oscillator

Abstract We have implemented a sapphire loaded superconducting cavity resonator in a novel phase stabilised loop oscillator at 10 Ghz and achieved a fractional frequency stability of 10–14 for 3 to 300 seconds integration time and a resonator Q of 3 x 108. We present here an overview of the oscillator.
