Abstract :
We present new experimental results of the generation of a high-frequency modulated electron beam in a diode with a ferroelectric plasma cathode. The energy of electrons in the modulated beam is significantly higher than that obtained in previous experiments, reaching 150 keV. The maximum amplitude of the modulated beam current reaches 65 A, which corresponds to a beam power of 4.5 MW. Efficient transport of the modulated electron beam in a guiding external magnetic field without distortion of its waveform is demonstrated. In addition, it was shown that the modulated beam could be efficiently transported through a slow wave structure without the application of the external magnetic field.
