Abstract
| A new X-band high-power rotating mode SLAC energy doubler (SLED)-type rf pulse compressor is proposed. It is based on a novel cavity type, a single open bowl-shaped energy storage cavity with highquality factor and compact size, which is coupled to the waveguide using a compact rotating mode launcher. The novel cavity type is applied to the rf pulse compression system of the main linac rf module of the klystron-based option of the Compact Linear Collider. Quasispherical rotating modes of TE1,2,4 and TE1,2,13 are proposed for the correction cavity and storage cavity of the rf pulse compression system, respectively. The storage cavity working at TE1,2,13 has a quality factor above 240 000 and a diameter less than 33 cm |
