Abstract :
A microwave pulse compressor operated with a superposition of eigen quasi-degenerated modes is considered. A proper choice of eigen frequencies and Q-factors allows essential reduction of diffraction losses during power storage. Peculiarities of power extraction by means of a high-power RF switch are analyzed. 30 GHz projects of multi-megawatt compressors based on: 1) dual-mode circular cross-section cavity as well as 2) four- mirror cavity with active grating are discussed.
