Research Topics


The major goal of the proposed program is to develop a long-pulse (greater than 1 microsend) microwave generator capable of delivering 2 kilojoules per pulse of microwave energy. The proposed source is called a Triaxial Klystron, and it incorporates unique and innovative features to eliminate the pulse shortening that has plagued other high-power microwave sources. During Phase II, experiments will be performed to quantify the relative importance of the techniques identified in Phase I to lengthen the output pulse. To implement these techniques and facilitate the commercialization of sources based on this technology, MRC is collaborating with major industrial companies as well as researchers at various government laboratories involved in HPM research. The final version of the Triaxial Klystron developed in Phase II will be tailored for microwave effects testing and delivered to Phillips Laboratory at the conclusion of the program. This will be a turn-key system powered by a unique modulator built by our SBIR partner, North Star Research Corporation.
