Abstract
A microwave pulse compressor has an elongated, cross-sectionally oversized waveguide resonator for decreasing the attenuation of the resonator, thereby increasing the resonator's QO The increased Q of the resonator guide results in more stored energy and greater output pulse power. The pulse compressor is constructed to suppress high order modes that can be generated in oversized waveguides. The higher order modes are suppressed by any means, including, separately or in combination, the input coupling design, choice of the resonator length, and the design of the output coupling structures. In one alternative aspect of the invention, the switch at the switch-out end of the waveguide resonator is a plasma switch, employing at least one dielectric window positioned in the resonator guide to have minimum effect on the resonator Q. The dielectric window contains a relatively large volume of a switch gas at low pressure within a switching section of the resonator guide at the guide's switch-out end. A static magnetic field can be provided for confining the plasma produced upon triggering to the region which produces the most effective switching action.
