Effects of wake fields on high intensity proton beam are studied, when it passes through idle coupled cavities. There is the same number of frequencies as the number of gaps that consist on the coupled cavity. Since cavities are designed for the accelerated beam, the shunt impedance for each mode is different from the designed value, when the beam is not accelerated. This change of shunt impedances reduces the detuning effect for the reduction of beam degradation.

KART (Kumatori Accelerator driven Reactor Test) project has started at Kyoto University Research Reactor Institute (KURRI) from the fiscal year of 2002. The purpose of this project is to demonstrate the basic feasibility of ADS, studying the effect of incident neutron energy on the effective multiplication factor of the subcritical nuclear fuel system. The proton FFAG accelerator complex as a neutron production driver for this project is now in the final stage of the test operation. The first ADS experiment will be held in this autumn by combining this FFAG complex with our Kyoto University Critical Assembly (KUCA) in KURRI. The developments and the current status of this FFAG accelerator complex, including the current status of this project, will be presented.
