<p>A microwave window assembly (14) for transmitting high power microwave energy from microwave propagating means (10) into the interior of a chamber (12) and including first (24) and second (26) windows formed of a dielectric material substantially transparent to microwave energy with the first window (24) sealed in a wall (12b) of the chamber and the second window (26) spaced rearwardly from the first window (24) to define a space therebetween. A cooling fluid is circulated in the space between the windows to cool the window positioned in the wall of the vacuum chamber and a waveguide tube (34) extends from the microwave propagating means to the rear surface (26b) of the second window (26) to define a waveguide surface. A clamp plate (30) positioned against the forward surface of the second window (26) includes a window opening (30d). The second window (26) extends radially outwardly beyond the waveguide surface to define an annular outer window portion (26c) outwardly of the waveguide surface.</p> |
