Design of high gradient, high repetition rate damped C-band rf structures
The gamma beam system of the European Extreme Light Infrastructure–Nuclear Physics project
foresees the use of a multibunch train colliding with a high intensity recirculated laser pulse. The linac
energy booster is composed of 12 traveling wave C-band structures, 1.8 m long with a field phase
advance per cell of 2?=3 and a repetition rate of 100 Hz. Because of the multibunch operation, the
structures have been designed with a dipole higher order mode (HOM) damping system to avoid beam
