The Helmholtz Linear Accelerator HELIAC is a superconducting (sc) continuous wave linear accelerator for heavy ions currently in development at GSI, the Helmholtz Centre for Heavy Ion Research in Darmstadt. The HELIAC offers variable output energies in between 3.5 MeV/u and 7.3 MeV/u and its main acceleration will be done in three cryo-modules. The assembly of the first cryo-module has just been finished in June 2023. The module houses three sc multi gap Cross bar H-mode (CH) acceleration cavities and a sc rebuncher cavity, as well as two sc solenoid lenses. The cavities are operated at 4 K at an accelerating gradient of up to 7 MV/m. The cold-string assembly took place in an ISO-class 4 cleanroom, which was finished in March, subsequently it was integrated into the cryo-module in a dedicated area in front of the cleanroom. Afterwards the module with a total weight of about 7 tons and a length of 5.5 m was shipped to GSI where it was integrated in a test area with connection to a 700 W cryo-plant and a beamline for tests with heavy ion beams. We will report on the assembly and the setup at GSI. First results of the tests, which started in November 2023, will be presented.
