Rosswag Engineering is producing plasma-exposed, 3D-printed cooling heads for the Wendelstein 7-X fusion reactor at the Max Planck Institute for Plasma Physics in Greifswald, Germany.

The Wendelstein 7-X is an experimental reactor built to both investigate the physical and technical fundamentals of stellarators for nuclear fusion power plants and demonstrate their principle suitability as an alternative to the Tokamak principle.

The reactor uses Rosswag’s water-cooled heads for thermal monitoring of the diverters located in the plasma vessel and protection of the mounted mirrors inside. Due to the heads’ plasma-exposed location and complex mounting position, the components must meet corrosion resistance standards; tight tolerances; and high requirements for magnetic, heat and radiation exposure.

Rosswag Engineering's holistic process chain enabled the firm to carry out all of the production steps in-house, from 3D printing to CNC machining and material analysis, ensuring complete documentation of all data and interfaces.
