Novel open cavity design for rotating mode rf pulse compressors

A new $X$-band high-power rotating mode SLAC energy doubler (SLED)-type rf pulse compressor is proposed. It based on a novel cavity type, single open bowl-shaped storage with high-quality factor and compact size, which coupled to the waveguide using launcher. The type applied compression system of main linac module klystron-based option Compact Linear Collider. Quasispherical modes ${\mathrm{TE}}_{1,2,4}$ ${\mathrm{TE}}_{1,2,13}$ are proposed for correction system, respectively. working at has quality above 240 000 diameter less than 33 cm. design in particular high-Q will be presented detail.
