Abstract : This report covers: (a) the present status of the high-power microwave facility at the Long Island Graduate Center, Farmingdale, New York; (b) analysis, design and experimental work connected with a proposed C-band dischargeable traveling wave resonator (TWF), using oversized, low-loss, multimode waveguide and capable of magnifying appreciably the peak powers currently available in high-power pulsed microwave sources for delivery in the form of intensified but narrower pulses to an external load; and (c) interaction of high microwave powers and fields with dielectric and metallic materials. The development of two different broadband, gaseous discharge type, C-band high-power microwave switches motivated by the switching requirements of the TWF, is reported. These have very low (0.2 db) insertion loss, high switching speed (30 and 10 nanoseconds, respectively) and are capable of handling peak powers in excess of one megawatt. One device is a low-pressure hydrogen gas wave guide thyratron and the other a dc-triggered, microwave spark gap operating in air at atmospheric or higher pressure. (Author)
