Abstract

A multicavity-magnetron (1) is used to generate microwaves for radar applications. Right-circular-cylinder cavities (2) in the multicavity-magnetron act like an electron whistle. When excited, the cavities produce a specific wavelength of microwave depending directly on the diameter of the cavity. These microwaves are then fed to a radar dish (4) where they are emitted as a radar beam. (Image Omitted)

Superconductor Enhanced Multicavity-Magnetron

      A multicavity-magnetron (1) is used to generate microwaves for
radar applications.  Right-circular-cylinder cavities (2) in the
multicavity-magnetron act like an electron whistle.  When excited,
the cavities produce a specific wavelength of microwave depending
directly on the diameter of the cavity.  These microwaves are then
fed to a radar dish (4) where they are emitted as a radar beam.

      Coating the interior of these cavities with a high- temperature
superconductor material (5) would enhance the efficiency of the
multicavity-magnetron.  This would provide more power to the radar
beam, thereby enhancing its signal-to-noise ratio.

      Cooling the multicavity-magnetron with liquid nitrogen to the
temperature required to maintain superconductivity is immediately
feasible and would not be detrimental to the operation of the
magnetron.
