  A high field-gradient RF system for a spiral FFAG is described. It is wideband to cover the frequency of 3 to 7.5 MHz. The beam will be accelerated with a high repletion rate of 100 Hz to fit requirements for hadron therapy. The cavity has a wide aperture of 90 cm in horizontal direction to allow a large excursion for beam acceleration. It has less than 40 cm in length to fit a very short straight section.

  A hadrontherapy accelerator assembly based on an FFAG ring and a variable energy H- cyclotron injector has been designed in the frame of the RACCAM project. The FFAG ring allows 2.1 Tm top rigidity, corresponding to 180 MeV proton top energy and 21.6 cm penetration depth and to 50 MeV per nucleon for carbon ions suitable for biological R&D). Variable energy extraction, bunch to pixel 3D scanning and multiport beam delivery are proposed in this installation. A prototype of a spiral sector scaling type of FFAG dipole is being built for proving the feasibility of the FFAG ring, subject to a second contribution in the conference. This paper will describe the accelerator assembly parameters and the beam properties.

  Three different muon decay ring configurations are being considered for a neutrino factory. A racetrack design is the current ISS baseline (as it allows greater flexibility in the choice of detector sites) but triangular and bow-tie rings have advantages in neutrino production rates*. Using tracking code simulations, a study of the latter two designs is carried out. Since spin depolarisation measurements have been proposed for muon energy calibration**, spin tracking is included in this study. Dynamic aperture is important and is also calculated.

  This paper presents beam dynamics studies regarding the variable energy operation of a spiral scaling FFAG (Fixed Field Alternating Gradient) accelerator designed for producing 70 to 180 MeV protons and acceleration simulations for different operation modes, corresponding to different extraction energies.

  EMMA - the Electron Model of Many Applications - is to be built at the STFC Daresbury Laboratory in the UK and will be the first non-scaling FFAG ever constructed. EMMA will be used to demonstrate the principle of this type of accelerator and study their features in detail. The design of the machine and its hardware components are now far advanced and construction is due for completion in summer 2009.
