Résumé

The superconducting magnet system for the new stellarator Wendelstein 7-X to be placed at Greifswald, Germany, consists of 50 non-planar and 20 planar large magnet coils. The conductor used is a cable-in-conduit type, composed of copper stabilized NbTi strands and eveloped by an aluminium alloy jacket. The individual winding packs are built up from six resp. three double layers, glass insulated and resin impregnated. A cast steel casing encapsulates each winding pack to achieve sufficient mechanical stiffness. The toroidal set up of the coil system weighs 400 tons and has a diameter of 11 meters. Operation will be at 6 Tesla and a coil current of 1.75 MA. Cooling is provided by supercritical helium. A fast de-energizing system protects the magnet from overheating in case of a quench.
