Experiences From the Assembly of the Magnet System for Wendelstein 7-X

Wendelstein 7-X represents the continuation of fusion experiments of the stellarator type at the Max-Planck-Institute for Plasma Physics. The size of device (725 t, height of 5 m, diameter 16 m) and the superconductive magnet system distinguish W7-X from earlier stellarators at the Max-Planck Institute. The paper describes the technologies and methods used for the assembly of the magnet system and it compiles the experiences gained. The assembly of the W7-X facility will be accomplished in 2014.
