Abstract

The electromagnetic radiation of an electron flow in a triode with a virtual cathode is studied from the viewpoint of a parametric resonance. It is shown that the phase modulation of the electrons and the radiation saturation take place due to the oscillations of the virtual cathode as a result of large space charge. An expression for the coherent radiation intensity of the electron flow in a resonator is derived. It is shown that the phase modulation depth and the radiation efficiency increase with an external electromagnetic wave.
