  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.

  The ion-optical layout of the two main synchrotrons and the high energy beam transport system of the FAIR project is summarized. SIS100 will be used to generate high intensity beams of all ion species from protons to uranium with a maximum rigidity of 100 Tm. The ion optical layout is optimized for the operation with heavy ions of medium charge states. For this purpose we developed a new ion optical design which provides a separation of the ionized beam particles from the circulating beam in each lattice cell. The chosen lattice structure provides a peaked loss distribution and enables the suppression of beam loss induced pressure bumps. Furthermore a compact layout of the extraction systems for slow and fast extraction at 100 Tm and 300 Tm has been developed. Since both synchrotrons are situated in the same tunnel, the SIS300 ion optical layout has to match the geometrical shape of the SIS100 precisely - although both rings use different lattice structures. The design of the beam transport system allows an effective parallel operation of the two synchrotrons, storage rings and experiments of the FAIR complex.
