| Abstract |
At the Heidelberg Ion Beam Therapy Centre HIT we operate a 4-rod RFQ as first stage of a 7 MeV/u injector linac followed by an IH-DTL. During the first years of patient treatment the injector performance was perfectly adequate, even though the transmission of the linac remained below the theoretical expectations. New developments in dose delivery technology already realised or to come in the future increase the demand on higher beam intensities which will finally result in shorter irradiation times. As measurements performed at our test bench have confirmed that there is a margin for higher transmissions especially for the RFQ we are currently preparing for a new RFQ design. While keeping the original design parameters, the new RFQ should be optimised with respect to the transmission of beams from different ion sources such as electron cyclotron resonance or electron beam ion sources. All parts of the RFQ will be put up for discussion including electrodes, stems, tank and the integrated rebuncher. The design work will profit from new concepts that have evolved at our own and other medical heavy ion facilities in operation and from the progress modern simulation tools have run through.
