Abstract

The excitation of UHF-oscillations by an electron beam in a disk loaded coaxial transmission line with combs on the inner and external conductors are theoretically investigated. The structure passage channel, where an annular electron beam propagates, is fully filled by plasma. The eigen waves of the plasma filled coaxial transmission line and their dependencies versus plasma density are investigated. It is shown that the plasma has resulted in essentially an enhancement of gain and at the same time widens the excited oscillation spectrum
