Low-level RF System for the SuperKEKB Injector LINAC

The low-level RF system of the KEKB injector linac has been upgraded for the SuperKEKB. To satisfy the operational requirement for the SuperKEKB that is 40times higher in luminosity compared with the KEKB, the main drive system in the low-level RF system of the KEKB injector linac was reconstructed. With recent technical developments in the solid-state amplifier, the configuration of the sub-booster system is expected to change. An outline of the low-level RF system for the SuperKEKB injector linac is described herein.
