ABSTRACT:
A cyclotron resonance maser microwave amplifier includes coaxial input and output waveguides. Coupling apparatus for cyclotron resonance maser microwave amplifiers and other microwave power systems is provided for transferring microwave power between first and second waveguides. Geometry permits unwanted modes to be effectively attenuated. The coupling apparatus includes first and second coaxial hollow metallic circularly cylindrical members. The first member forms a first waveguide section. A second waveguide section coaxial therewith is bounded internally by the first member, and externally by the second member. The first member has a plurality of apertures for transferring microwave power between the first and second waveguide sections. The apertures are small relative to the radius of the first member and are spaced around the circumference of the first member in a generally symmetrical array. The apertures may be located in a plurality of axially extending grooves arranged in a generally symmetrical array with a helical twist, and are substantially filled with dielectric inserts which have a relatively short length and small cross-sectional area. The inserts provide a hermetic seal so that the waveguides may contain different media, as desired. Coolant channels are provided adjacent the apertures to dissipate heat generated in the dielectric inserts.
