      abstract     = {The HElmholtz LInear ACcelerator (HELIAC), currently under
                      construction at GSI, has high beam transmission requirements
                      due to the application of superconducting components in
                      continuous wave operation, which can only be achieved by
                      smart beam matching to the superconducting section. This
                      work is mainly concerned with the injection into the
                      superconducting HELIAC section, i.e., with the measurement
                      and optimization of the beam transport and with the design
                      of the normal-conducting injector linac. For this purpose, a
                      reconstruction algorithm is developed in this thesis to
                      calculate the parameters of the longitudinal particle
                      density-distribution. Its implementation and practical
                      application are presented, which is suitable for the
                      optimization of both the current HLI injector and the future
                      standalone HELIAC injector. Furthermore, a novel beam
                      collimation system has been designed and put into operation,
                      which will be used for beam-based alignment by means of a
                      so-called pencil beam. Finally, the new design of the
                      normal-conducting injector linac created in the course of
                      the thesis is presented, using a drift-tube accelerator
                      consisting of two Interdigital Hmode (IH) cavities with
                      Alternating Phase Focusing (APF) beam dynamics. Special
                      emphasis was placed on optimal beam characteristics. By
                      minimizing the emittance growth along the drift-tube
                      accelerator, and the consequent improvement of the beam
                      brilliance, the performance of the HELIAC can be
                      significantly improved.},
