<p>An open waveguide electromagnetic wave radiator is used to radiate electromagnetic waves of cyclotron frequency to plasma (36) within a vacuum container (38). This radiator comprises a waveguide (30) having evacuation holes (42-1, 42-2) and containing ridges (32, 34) having a T-shaped cross section, a radiator section (31) connected to, and integrally formed with, the open end of the waveguide (30), evacuation pipes (44-1, 44-2) connected to the evacuation holes (42-1, 42-2), a chamber (46) enclosing the closed end portion of the waveguide (30) and the evacuation pipes (44-1, 44-2), and a pump (50) for evacuation the chamber (46). The evacuation holes (42-1, 42-2) are made in that wall of the waveguide (30) to which the leg of one of the ridges (32, 34) is connected.</p> |
