Abstract
A modulated bunched electron beam incident on the inner conductor 16 of a coaxial structure launches TEM waves that are distributed to multiple radial waveguides 22 around the outer conductor 14 of the coaxial structure. A tuning piston 32 may be moved axially within the outer conductor for matching the impedance of the coaxial structure to the waveguide array.
Claims20
A converter apparatus for converting kinetic energy of an electron beam into radio frequency (RF) energy, comprising:
- a drift tube for bunching said electron bream;
- a tubular outer conductor disposed along an axis, said tubular outer conductor having a first end connected to said drift tube for receiving said bunched electron beam, and a closed second end;
- a tubular inner conductor disposed coaxially within said outer conductor, said inner conductor spaced from said outer conductor, said inner conductor having a first end for receiving said bunched electron beam and a second end;
- and
- a plurality of coplanar waveguides extending in radial directions with respect to said axis of said outer conductor and disposed between said first and second ends of said inner conductor, each waveguide of said plurality of coplanar waveguides having a waveguide end connected to said outer conductor and a waveguide opening at each said waveguide end.
A converter apparatus for converting kinetic energy of a modulated electron beam into radio frequency (RF) energy, comprising:
- a drift tube for bunching said electron beam;
- a coaxial structure for receiving said bunched electron beam and for launching TEM waves, said coaxial structure comprising a tubular outer conductor and an inner conductor, said outer conductor disposed along an axis, said outer conductor having a first end connected to said drift tube and a closed second end, said inner conductor disposed coaxially within said outer conductor, said inner conductor spaced from said outer conductor and having a first end and a second end;
- and
- at least one waveguide array connected to said outer conductor for receiving said TEM waves.
