Abstract
Apparatus for generating high power microwaves and for radiating the microwave power in the HE.sub.1,1 mode into a confined plasma is disclosed. The apparatus includes a microwave generator and mode converters to convert the generated microwave power into the rectangular HE.sub.1,1 mode. A hermetically sealed rectangular HE.sub.1,1 mode power coupler is used between the plasma and a main waveguide run to seal the main waveguide run and the generator from the plasma. The power coupler comprises an input rectangular HE.sub.1,1 mode waveguide, an output rectangular HE.sub.1,1 mode waveguide and a plurality of dielectric sealed apertures through a common wall between the input and output waveguides. Power absorbed by the power coupler is removed by cooling fluid which is circulated through the common wall between the apertures.
