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...
