Research on Super Heavy Elements (SHE) is a fundamental component of scientific inquiry. The GSI Helmholtz Centre for Heavy Ion Research is an institution engaged in the discovery of new elements. It has successfully identified elements 108 to 112, made possible through the utilization of the UNILAC (Universal Linear Accelerator), which delivers 11.4 MeV/u heavy ion beams. For further synthesis of new elements, HELIAC (Helmholtz Linear ACcelerator) is currently constructed at GSI. In addition a new transfer channel from HELIAC to UNILAC for integration of HELIAC into existing beamlines, using bending- and focusing magnets, is being designed, transferring particles from HELIAC into experimental halls or further accelerators. To build this channel, the beamline is investigated using beam dynamics simulations for applicability for several energies and collimation. Through a parameter study, the optimal magnetic strengths of the magnets are determined. The HELIAC will provide variable energies between 3.5 and 7.3 MeV/u. Therefore, it is crucial to use the simulation to identify the parameters for various energies. The parameter study cannot be carried out for each energy individually. Accordingly, relationships between the parameters and energy are investigated. This allows the magnets to be adjusted for each energy, ensuring high transmission and beam quality for delivered heavy ion beams.
