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.
