JAR WINDOW FOR INPUT AND/OR OUTPUT OF MICROWAVE ENERGY Russian patent published in 2012 - IPC H01J23/36 

FIELD: electricity.

SUBSTANCE: device to transmit microwave capacity at the E₁₁ wave comprises coaxially arranged section of a round wave guide with a vacuum-tight soldered-in dielectric disc (DD) and two sections of rectangular wave guides connected to the section of the round wave guide at its opposite ends, and also one or two metal tubes (MT) for a cooling liquid. Each MT is placed in an appropriate slot arranged in DD along its diameter at one DD side. Each MT is installed along the appropriate slot and is soldered with its walls along the entire length. Ends of each MT are soldered to the wall of the round waveguide section in a vacuum-tight manner. The longitudinal axis of each MT lies in the place of the axial section of the round waveguide section arranged in parallel to wide walls of the rectangular waveguide sections.

EFFECT: improved heat removal from a dielectric disc of a jar window and higher level of average microwave capacity sent via a jar window.
