  Danfysik and Siemens have entered a cooperation to market and build Particle Therapy* systems for cancer therapy. The accelerators will consist of an injector (7 MeV/u proton and light ions), a compact and simple synchrotron and a choice of fixed-angle horizontal and semi-vertical beamlines together with gantry systems. The optimized lattice configuration, including the design of injection and extraction systems, provides large transverse phase space acceptance with minimum magnet apertures. The resulting synchrotron will have light magnets, low values of peak power for pulsed operation and minimum dc power consumption. The beam can be accelerated to the maximum magnetic rigidity of 6.6 Tm in less than 1 s. A beam of 48-250 MeV protons and 88-430 MeV/u carbon ions can be slowly extracted during up to 10s. The intensity for protons and carbon ions will be well beyond the needs of scanning beam applications. The design and performance specs of the synchrotron will be described in detail including simulations. Design and manufacture of the subsystems are in progress. *Particle Therapy is a work in progress and requires country-specific regulatory approval prior to clinical use.
