An accelerator facility of FFAGs at KURRI has been operated since 2009. It delivers 100 - 150 MeV proton beams to the subcritical nulcear fuel systems to investigate ADS ( Accelerator Driven System ). Also proton beams from our facility are used for studies of radiation damage for materials and living animals for BNCT basic studies. Intensity improvement programs are still on going. The c ... More

At the KURRI FFAG Complex, research and development work has been continued to improve the beam intensity. Since we still observed several beam losses at the 150 MeV FFAG main ring, several beam measurements had been done to investigate the reason of beam loss. In this presentation, the details about these measurements are described. In addition, beam measurement instruments and recent activit ... More

The closed orbit distortion in scaling FFAGs can differ significantly from that predicted by the linear response matrix. This is the result of dipole feed-down from the high order multipoles inherent in the magnets of such a machine. Feed-down also leads to detuning with COD amplitude. In this presentation these effects are studied in simulation and the results compared with theory.

The low-energy cyclotrons have been widely applied for positron emission tomography (PET), which is an advanced method for early diagnostic of cancer. To promote research and talent cultivation, Huazhong University of Science and Technology (HUST) has been developing a compact 10MeV cyclotron CYCHU-10, which could be used for short-life isotopes production. Automated successful operation of the CY ... More

FFAG accelerators offer unique properties like an ability to transport and accelerate beams with large momentum spread and large emittance. The applications of FFAG accelerators for various muon projects are reviewed. The status of developments on the Neutrino Factory, nuSTORM and PRISM is briefly presented and prospects for a future is outlined.

I will discuss high intensity FFAG design and related study. It may include a design of post-ISIS facility based on FFAG accelerators and its prototype knows as the FETS FFAG. Simulation of high intensity beams (with KURRI FFAG parameters) will be another topic if reasonable results were obtained by the workshop.

The main purpose of the ARIEL project is to provide TRIUMF with two new sources of radioactive ion beams. One of these two new sources will be using photo-fission reactions driven by the electron beam from our 50 MeV 500 kW linear accelerator (under commissioning). Electron to photon conversion has never been tried with such a high beam power. Possible technological solutions are being studied. We ... More

A new design scheme for a spiral-sector FFAG accelerator with the simple matching technique has been proposed. In ordinary design schemes for the spiral-sector FFAG with high momentum ratio and small mean radius, many geometrical parameters concerning to a chamfer of pole edge, the pole shape and field clamps should be optimized to match the design indexes of the lattice optics: local k value, eff ...

Muons, in particular, negative muons may become very useful for promising a resolution to the fundamental serious problems of nuclear energy development. In this application, obviously, it is needed that a super intense negative muon source whose intensity is more than 10$^{16}$ $\mu^-$/sec. But at the same time in the muon source, the energy cost for muon production (how much energy is needed ... More

Center for Accelerator and Beam Applied Science of Kyushu University has three accelerators; an injector cyclotron, a FFAG synchrotron and a tandem accelerator. Radiation safety inspections to utilize beams from the cyclotron and the tandem accelerator were successfully passed. The status of the center will be reported in the workshop.

Isochronous FFAG accelerators have highly potential applications in high power proton driver, hadron therapy and irradiation with low energy electron beams, due to the breakthrough of pulse mode adopted by classical FFAGs. Preliminary design of an electron FFAG with serpentine acceleration will be introduced. The development of a 10 MeV cyclotron for PET isotopes production, and a proposal of a pr ... More

In this talk I will give an overview of the progress toward high power hadron FFAGs, focusing on the KURRI-FFAG experimental campaigns and the IBEX Paul trap experiment being constructed at RAL. I will also give a perspective on some of the challenges we are yet to face, from theory and simulation through to more practical issues.

Modelling of the FFAG magnets is so far either with the simplified transfer matrix or with TOSCA field maps. The former is easy to calculate and very fast to obtain the results, but not accurate or missing details of the end fields. The latter is much more realistic, but takes time to calculate. It is not practical to optimise the parameters with these. We have developed the FFAG megnets mode ... More
