The present status of system- and technical design and R&D for the new heavy ion synchrotrons SIS100 and SIS300 and the HEBT system is summarized. The overall machine planning and the general layout has been completed and the detailed technical machine design has been started. Device and component specifications, technical parameter lists and technical design reports are in preparation with the goal to enable international partners or industry to finalize the component design to achieve production readiness. In the frame of international working groups the distribution and sharing of the work packages, especially of the cryomagnetic system is under discussion.

The HIT medical accelerator at Heidelberg, Germany, is the first dedicated heavy-ion cancer therapy facility in Europe, consisting of a two-stage injector Linac followed by a compact synchrotron. It features three treatment places: two horizontal beam lines, where treatment will be carried out from 2008 using proton and carbon beams, and the first 360° rotating heavy-ion Gantry structure. The accelerator sections of this facility were designed and constructed by GSI, which thereafter was in charge of the commissioning. By now, the required medical beam quality has been achieved in both horizontal beam lines, and beam commissioning of the Gantry structure has started. In this contribution we describe the technical layout of beam diagnostic devices and present measurement data taken in high-energy beam transport lines and patient treatment places.

A specially designed accelerator facility for tumour irradiation located at the Heidelberg University Hospital was built up, the commissioning is still ongoing. Technically the Heidelberg Ion Therapy Center (HIT) fully relies on the three dimensional intensity-controlled rasterscan technique developed at GSI. This method demands for smoothly extracted ion beams (from protons to oxygen) from the HIT synchrotron. For this purpose a RF knock-out system consisting of a RF-exciter in combination with an electrostatic septum, two septum magnets and two sextupoles is used. To characterize the extracted beams scintillators for low intensities and ionization chambers for higher currents are installed in the high energy transport lines. Using a PXI-based DAQ system full spills are recorded with a time bin of 100 μs. Typical raw data will be shown as well as derived statistics like Fourier spectra and maximum-to-average ratios that proof the beam quality for its applicability to produce outstanding dose distributions via beam scanning. In addition, safety aspects like the performance of the spill interrupt procedure will be demonstrated with measured data.
