A clinical facility for cancer therapy using energetic proton and ion beams (C, He and O) is under construction and will be installed at the Radiologische Universitätsklinik in Heidelberg, Germany. It consists of two ECR ion sources, a 7 MeV/u linac injector, and a 6.5 Tm synchrotron to accelerate the ions to final energies of 50-430 MeV/u. The linac comprises a 400 keV/u RFQ and a 7 MeV/u IH-DTL operating at 216.8 MHz. The commissioning of the linac with beam was performed in three steps for the LEBT, the RFQ, and the IH-DTL. For this purpose a versatile beam diagnostic test bench has been used consisting of a slit-grid emittance measurement device, transverse pick-ups providing for time of flight energy measurements, SEM-profile grids, and different devices for beam current measurements. In this contribution the procedure and the results of the successful commissioning in the year 2006 of the linear accelerator are reported.
