Abstract :
A powerful X band oscillator is reported, with a frequency stability comparable to a quartz clock of high quality. It is realised by coupling externally a standard reflex klystron 2K 25 to a high-Q factor (108) superconducting cavity. The observed frequency standard deviations in one second (10¿10 in relative value) are in accordance with the theory.
