Research and development in preparation of the proposed HElmholtz LInear ACcelerator (HELIAC) is performed by a collaboration of GSI, HIM and Goethe University Frankfurt. It is intended for various future experiments with special focus on heavy ion energies near the coulomb barrier for super-heavy element research. The linac will be operated in cw-mode and with a mass-to-charge-ratio up to 6. With a required minimum energy spread over a wide output energy range from 3.5 to 7.3 MeV/u the beam dynamics design is challenging. It is based on EQUUS (equidistant multi-gap structure) using highly efficient superconducting (sc) CH-DTL cavities with an accelerating gradient up to E_a = 7.1 MV/m. The worldwide first beam test with a sc multi-gap CH-DTL cavity in 2017 was a milestone in the R&D work of GSI, HIM and IAP. The layout for the entire linac has recently been updated and optimized and an advanced beam dynamics design for the HELIAC was developed.
