Crossing of integer resonance in scaling FFAG accelerator has been studied experimentally with the injector of 150MeV FFAG complex at Kyoto University Research Reactor Institute (KURRI). The results were analyzed based on harmonic oscillator model and compared with beam tracking simulations.

Straight section in scaling FFAG accelerator has been explored and scaling law for straight section has been investigated. Under these studies, dispersion suppressed straight section, which could be useful for efficient RF acceleration, can be designed in ordinary scaling FFAG ring accelerator.

Harmonic number jump (HNJ) acceleration in scaling FFAG accelerator, especially for muon acceleration in neutrino factory, has been studied. Criterions for HNJ acceleration were clarified and beam tracking simulations have been carried out.

Accelerator based neutron source with an internal target (ERIT-emittance recovery internal target) placed into the proton storage ring has been developed. In this scheme, the beam and energy degradation caused by the target are cured by ionization cooling and the thermal and epi-thermal neutron flux of more than 1x10⁹ n/cm²/sec can be obtained. The experimental results will be given in the conference.

The accelerator–based neutron source using ERIT (Energy/emittance Recovery Internal Target) scheme has been constructed at KURRI (Kyoto University Research Reactor Institute). And the first beam test was successfully completed in March 2008. In this poster, recent status of beam studies will be presented.
