Beam Dynamics Studies for a High Current Ion Injector
  Recent ion source developments resulted in the generation of high brilliance, high current beams of protons and light ions. After extraction and transport the beams with large internal space charge forces have to be captured, bunched and preaccelerated for the injection into the following driver part of a new generation of high intensity beam facilities for neutron sources, energy production, transmutation e.g. A combination of RFQ and DTL is considered to be a good solution for such a high current ion injector. Some preliminary beam dynamics layouts have been investigated by multiparticle simulations. Basic parameters like frequency, ion energy and sparking have been varied for the International Fusion Material Irradiation Facility (IFMIF) scenario as an example. The main interest was directed to high transmission, low losses and emittance conservation. The beam matching to the RFQ is shortly discussed as well as the matching between RFQ and DTL.
