For future experiments with heavy ions near the coulomb barrier within the super-heavy element (SHE) research project a multi-stage R&D program of GSI, HIM and IAP is currently in progress. It aims at developing a superconducting (sc) continuous wave (CW) LINAC with multiple CH cavities as key components downstream the upgraded High Charge State Injector (HLI) at GSI. The LINAC design is challenging due to the requirement of intense beams in CW-mode up to a mass-to-charge ratio of 6 while covering a broad output energy range from 3.5 to 7.3 MeV/u with minimum energy spread. After successful tests with the first CH cavity in 2016 demonstrated a promising maximum accelerating gradient of 9.6 MV/m, the worldwide first and successful beam test with this superconducting multi-gap CH cavity in 2017 was a milestone in the R&D work of GSI, HIM and IAP. In the light of experience gained in this research so far, the Beam Dynamics layout for the full LINAC was recently updated and significantly optimized. The corresponding simulations will be presented within this contribution.
