Electron Beam Dynamics

This paper presents particle-in-cell simulation of the reflex triode with radially diverging magnetized electron beam. Dynamics of the electron beam and generation characteristics of the reflex triode are studied in the work. It is shown that two virtual cathodes are formed in it. It was calculated that the peak power of the microwave radiation reaches P=19 MW at the beam current I0=5 kA and potential of the cathode Uc=‒100 kV. There is a peak in the microwave radiation spectrum at the frequency ν = 5.2 GHz.
