SKIP - A PULSE COMPRESSOR FOR SUPERKEKB

A C-band RF pulse compressor “SKIP”, which stand for SuperKEKB Injector Pulse compressor, has been developed for the SuperKEKB project aiming luminosity upgrade of the present KEK-B factory. The design of the compressor using TE0,3,8 mode cylindrical cavity is based on the “LIPS” used in the LEP injector S-band linac. Detailed dimensions of the cavity have been optimized for C-band (5712 MHz) with low power models. In the high power test of the pulse compressor, a peak output power of 200 MW is achieved with the input RF power of 43MW in 2 µsec duration.
