The NS-FFAG is a novel idea of a fixed field accelerator which has advantages in flexible design and machine operation for fixed field accelerator. However, due to the large tune variation with energy, fast acceleration is a key issue to circumvent the resonance problem in a linear NS-FFAG. At the moment, there is no numerical study of how fast it needs be. In this paper, using a lattice of a NS-FFAG for particle therapy, results of tracking study including acceleration rate, positioning tolerance are presented.

Spot scanning irradiation is a next generation treatment scheme of particle therapy. The pulsed beam of FFAG accelerator is well fitted to the treatment. In order to form a uniform dose distribution in the target volume, intensity modulation is a requirement in spot scanning and it requires special consideration in injection in order to realize short time treatment using the pulsed beam of the FFAG. In this paper, injection related issues of NS-FFAG are discussed from the point of particle therapy, especially for spot scanning.

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.
