Dispersion relation and growth rate in thermal plasma-loaded traveling wave tube with corrugated waveguide hollow electronbeam

A theory of relativistic traveling wave tubewith magnetized thermal plasma-filled corrugated waveguidewith annular electron beam is given. The dispersionrelation is obtained by linear fluid theory. The characteristicof the dispersion relation is obtained by numericalsolutions. The effect of plasma density, corrugated period,waveguide radius and plasma thermal effect on the dispersionrelation and growth rate are analyzed. Some usefulresults are given.
