ABSTRACT: A theory of relativistic traveling wave tube (RTWT) with magnetized cold plasma-filled
corrugated waveguide with solid electron beam is given. The entire system
influenced a strong longitudinal magnetic field that magnetized plasma and
electron beam. The characteristic of the dispersion relation is obtained by
numerical solutions. The effect of electron beam density, corrugated period,
waveguide radius on the dispersion relation and growth rate is analyzed. Some
useful results are given.
