Abstract :
The measurements of the short-term and long-term stability of an X band klystron, stabilised by a high-Q-factor super-conducting cavity, show that this signal has a stability of 3 parts in 1012 for a period of measurement of 10 s and a frequency shift of 1.7 Hz during 30 min. These performances have been obtained by improving the operating parameters of the oscillator.
