As a first step, the cw-Linac demonstrator was the first part for the proposed cw-LINAC@GSI. A superconducting CH-cavity, embedded by two superconducting solenoids has been tested with beam in 2017/2018 successfully. The sc CH-structure, designed at Goethe-University of Frankfurt, is the key component and offers a variety of research and development. As a next step the first cryostat of the HELIAC, the so called Advanced Demonstrator will be tested in the same testing environment at GSI. Therefore, a bigger concrete Bunker as well as the connection to the cryo plant is under development. The cold string was assembled in a rehabilitated clean room at GSI. For future clean room assemblies a fully equipped clean room is under preparation at Helmholtz-Institut Mainz. The mechanical suspension, composed of hanging components on crossed steel ropes, is a reliable concept to prevent the displacement during cool down. The cryogenic systems as well as all other mechanical tasks were solved. These and the future Advanced Demonstrator preparation will be presented.
