Wendelstein 7-X Torus Hall Layout and System Integration

Wendelstein 7-X (W7-X) is an experimental magnetic fusion device presently under construction in Greifswald, Germany, to study the stellarator concept at reactor relevant parameters and steady-state conditions. It is located nearly in the center of a 30 m × 30 m × 24 m hall. A large number of components need to be placed in close proximity of the torus to provide the system with the required means, e.g. cryogenic gases, cooling water, electricity, and to integrate it with the peripheral diagnostic and heating components. The arrangement of these components has to be supported by suitable structures, and has to be optimized to allow for installation, maintenance, and repair. In addition, space has to be provided for escape routes and for sufficient distance between components that could negatively influence each other's performance, etc. This paper gives an overview over the guiding principles and used tools for optimizing the layout of all components in the torus hall.
