Abstract :
This paper presents the results of an experimental study of the self-modulation in power of the pulsed microwaves produced by a 38 GHz relativistic backward-wave oscillator excited with an electron beam of duration 5 ns. The experimental data are in good agreement with the predictions of a PIC numerical simulation.
