ABSTRACT:
A microwave window assembly for transmitting high power microwave energy from microwave propagating means into the interior of a chamber and including first and second windows formed of a dielectric material substantially transparent to microwave energy with the first window sealed in a wall of the chamber and the second window spaced rearwardly from the first window 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 extends from the microwave propagating means to the rear surface of the second window to define a waveguide surface extending from the microwave source to the rear surface of the second window. A clamp plate positioned against the forward surface of the second window includes a window which defines a forward extension of the waveguide surface extending forwardly into the space between the windows to a location proximate the rearward surface of the window positioned in the wall of the vacuum chamber. The second window extends radially outwardly beyond the waveguide surface to define an annular outer window portion outwardly of the waveguide surface and the window assembly further includes a seal plate positioned against the rearward surface of the second window and defining an annular groove confronting the rear surface of the outer annular portion of the second window. An elastomeric annular seal is received in the groove and sealingly engages the rear surface of the outer annular window portion.
