Abstract

An open waveguide electromagnetic wave radiator is used to radiate electromagnetic waves of cyclotron frequency to plasma within a vacuum container. This radiator comprises a waveguide having evacuation holes and containing ridges having a T-shaped cross-section, a radiator section connected to, and integrally formed with, the open end of the waveguide, evacuation pipes connected to the evacuation holes, a chamber enclosing the closed end portion of the waveguide and the evacuation pipes, and a pump for evacuating the chamber. The evacuation holes are made in that wall of the waveguide to which the leg of one of the ridges is connected.
