Abstract:
1. An output window for a vacuum electron device, comprising: an output waveguide; an intermediate layer of dielectric material joined to the interior of the output waveguide with a vacuum-tight seal; upper and lower layers of dielectric material spaced apart from the intermediate layer and arranged above and below, respectively, the intermediate layer in a vertical orientation of the output waveguide, the upper and lower layers including respective openings; supports extending inwardly into the output waveguide and supporting the upper and lower layers, respectively; pillars extending through the openings in the lower layer and supporting the intermediate layer; wherein the openings in the upper and lower layers permit a venting of a region between the upper layer and the intermediate layer and a region between the lower layer and the intermediate layer during the sealing of the intermediate layer while the intermediate layer is supported by the pillars.
