Manufacture of cryostat components for Wendelstein 7-X

Wendelstein 7-X (W7-X) is a follow-up of the successful stellarator W7-AS and is presently being built at the Greifswald branch institute of IPP. One of the main parts of the stellarator is the cryostat, which provides the thermal protection of the coil system. Construction of the cryostat of W7-X is based on the experience gained during design, construction and test of the demo-cryostat [Fusion Eng. Des. 56–57 (2001) 861]. The design of the main components of the cryostat, in particular the plasma vessel, the outer vessel, the ports and the support structure is finished, and manufacture by European industry has started.
