MICROWAVE POWER OUTPUT WINDOW Russian patent published in 2020 - IPC H01J23/36 H01P1/08 

FIELD: electronic equipment.

SUBSTANCE: invention relates to electronic and accelerating equipment, namely to vacuum-dense waveguide windows for output of microwave energy, and can be used in creation of super-powerful klystrons. Window for outputting microwave energy, integrated with output resonator of super-powerful klystron, comprises output rectangular waveguide, shorted at one end and having common wall with output resonator of super-powerful klystron, vacuum-tight ceramics made in form of ring. At that, rectangular waveguide consists of straight, ring-shaped and connecting sections, besides, straight and ring-shaped sections of waveguide are located perpendicular to each other and have identical section, and ring-shaped section of waveguide is enclosed by output resonator. In common wall of waveguide and resonator in vertical plane there is at least one communication slot with rounded edges, angle of slot opening is not more than ½ λ_e, number of slots n is determined by the relationship n = ((2π-0.5λ_e)/λ_e)+1, where n is an integer rounded down, λ_e is the electric wavelength in the circular waveguide, rad; ceramic ring near common wall of waveguide and resonator is located at minimum distance, providing its thermocompensated attachment to ring-shaped section of waveguide.

EFFECT: eliminating additional inhomogeneities in the output waveguide, providing reliability at power exceeding 30-40 MW in the S-band.
