Electromagnetic wave transmission systems including a dielectric window for transmitting high-frequency highpower electromagnetic energy to a load from a source of suchenergy such as a resonant cavity of a klystron

Claim 1

A KLYSTRON INCLUDING AN ELECTRON GUN SECTION, A RADIOFREQUENCY INTERACTION SECTION AND A COLLECTOR SECTION DEFINING AN EVACUATED ENVELOPE, SAID RADIO-FREQUENCY INTERACTION SECTION COMPRISING A PLURALITY OF AXIALLY ALIGNED RESONANT CAVITY PORTIONS, EACH RESONANT CAVITY PORTION CONTAINS ELECTROMAGNETIC WAVE ENERGY AND INCLUDES AN INTERACTION GAP AND CONDUCTIVE METALLIC SURFACES WITHIN THE EVACUATED ENVELOPE, AND AN ELECTROMAGNETIC WAVE TRANSMISSION SYSTEM ASSOCIATED WITH AT LEAST ONE OF SAID RESONANT CAVITY PORTIONS, SAID ELECTROMAGNETIC WAVE TRANSMISSION SYSTEM COMPRISING A WAVEGUIDE SECTION CONTAINING STANDING WAVE ENERGY HAVING ALTERNATE REGIONS OF LOW AND HIGH INTENSITY ELECTRIC FIELDS, SAID WAVEGUIDE SECTION BEING PROVIDED WITH A DIELECTRIC WINDOW TRANSPARENT TO ELECTROMAGNETIC WAVE ENERGY MOUNTED THEREIN, SAID WINDOW BEING LOCATED IN THE LOW INTENSITY ELECTRIC FIELD REGION WITHIN SAID ELECTROMAGNETIC WAVE TRANSMISSION SYSTEM BETWEEN THE HIGH INTENSITY ELECTRIC FIELD REGION IN SAID WAVEGUIDE SECTION AND SAID ASSOCIATED RESONANT CAVITY.
