TI - Progress on a 30 - 350 MeV Normal-Conducting Scaling FFAG for Proton Therapy J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - We present our progress on a new design for a 30 - 350 MeV scaling FFAG for proton therapy and tomography - NORMA (NOrmal-conducting Racetrack Medical Accelerator) which allows the realisation of proton computed tomography (pCT) and utilises normal conducting magnets in both a circular and racetrack configuration which are designed using advanced optimisation algorithms developed in PyZgoubi. The ring and racetrack configurations have average circumferences of around 60 and 70 m respectively, peak magnetic fields of < 1.8 T, average orbit excursions < 50 cm and dynamic aperture calculations of > 50 mm.mrad using a novel technique. The racetrack design has a total magnet-free straight length of 4.9 m at two opposing points, designed to ease injection and extraction systems.
