Non-scaling fixed field alternating gradient (NS-FFAG) accelerators combine a number of advantages, such as rapid particle acceleration and large acceptance. These features make NS-FFAGs particularly interesting for medical applications. NS-FFAGs could be used for cancer therapy, which may lead to significant size and cost reductions in comparison to other accelerator types. Cancer therapy with protons or carbon ions is advantageous in comparison to conventional radiation treatment amongst other things due to the higher biological effectiveness. This paper discusses the basic magnet design issues for the PAMELA project. PAMELA is a prototype proton/carbon-ion therapy facility.

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.
