Abstract
A plasma wave tube is described in which a pair of counterpropagating electron beams are injected into a waveguide housing in which a plasma is formed, prefeferably by an array of fine wire anodes. The electron beams couple with the plasma to produce electron plasma waves, which radiate electromagnetic energy for beam voltages and currents above established threshold levels. A rapid control over output frequency is achieved by controlling the plasma discharge current, while the output power can be controlled by controlling the voltage and/or current levels of the electron beams.
