Recent ion source developments resulted in the generation of high brilliance, high current beams of protons and light ions. After extraction and transport the beam with large internal space charge forces has to be captured, bunched and pre-accelerated for injection into the following driver of the new generation high intensity beam facilities as being discussed for neutron generation, energy production, transmutation e.g.. A combination of RFQ and DTL is considered to be a good solution for such a high current injector. Some beam dynamics lay-outs have been investigated by multiparticle simulations, when basic parmeters like frequency, ion energy or sparking limit are varied. The main interest was directed to low losses and emittance preservation. The sensitivity of the beam matching into the RFQ as well the transition from RFQ to DTL will be discussed.
