Abstract
Plasma wave tubes are disclosed having waveguide injection systems configured for injection of an RF signal to prebunch the electron beam of the tube and thereby control the frequency of an RF output signal. Preferred embodiments of the injection system include a plurality of rectangular waveguides arranged radially about a cylindrical waveguide member and joined to it for communication with its interior. Plasma wave tubes (140) are also disclosed that utilize the injection system as a collector (44C) to couple an RF output signal from the tube.
