The Heidelberg Ion Beam Therapy Facility (HIT) is the first dedicated proton and carbon cancer therapy facility in Europe. It uses a full 3D intensity controlled raster scanning dose delivering method. The ion energy ranges from ca. 50 to 430 MeV/u corresponding to ion penetration depths of 20 to 300 mm in water. The HIT facility comprises the only heavy ion gantry worldwide designed for the beam transport of beams demanding a magnetic rigidity from 1 to 6.6 Tm. The gantry rotation of 360° enables beam scanning patient treatment from arbitrary directions. The libraries of carbon and proton pencil beams at the gantry are now offered with the whole variety of ion beam properties, i.e. 255 energy steps, 4 beam foci, 360°, and 10 intensities (10⁶-1010/spill). The beam has to be adjusted only for a fraction of possible combinations of energy, focus, and gantry angle. These are taken as base points for a calculation of an overall number of about 37,000 different set values per ion type, and one intensity step according to the data supply model. This paper gives an outline on the practical concepts and results of adjusting the required beam properties independent of the gantry angle.
