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.

  The neutrino beam produced from muons decaying in a storage ring would be an ideal tool for precise neutrino cross section measurements and search for sterile neutrinos due to its precisely known flavour content and spectrum. In the proposed nuSTORM facility pions would be directly injected into a storage ring, where circulating muon beam would be captured. The racetrack FFAG (Fixed Field Alternating Gradient) option for nuSTORM decay ring offers a very good performance due to a large dynamic and momentum acceptance. Machine parameters, linear optics design, beam dynamics and injection system for nuSTORM FFAG ring are discussed in this paper.
