	Increasing the repetition rate of FFAG accelerators is one way of obtaining high average beam current. However, in order to achieve beam powers of up to 10 MW for applications like ADSR, the number of particles per bunch has to be approximately the same order in an FFAG as in a high power synchrotron. Collective effects such as space charge then become crucial issues. To understand high current beam behaviour in FFAGs, an international collaboration has been established to carry out an experimental programme using the FFAGs at Kyoto University's Research Reactor Institute, KURRI. The goal is to demonstrate acceleration of high bunch charge and identify the fundamental limitations. In this paper, we will show simulation results toward the first beam experiment which is planned for later in 2013.

Increasing the repetition rate of FFAG accelerators is one way of obtaining high average beam current. However, in order to achieve beam powers of up to 10 MW for applications like ADSR, the number of particles per bunch has to be approximately the same order in an FFAG as in a high power synchrotron. Collective effects such as space charge then become crucial issues. To understand high current beam behaviour in FFAGs, an international collaboration has been established to carry out an experimental programme using the FFAGs at Kyoto University's Research Reactor Institute, KURRI. The goal is to demonstrate acceleration of high bunch charge and identify the fundamental limitations. In this paper, we will show simulation results toward the first beam experiment which is planned for later in 2013.
