Fabrication of the planar coils for WENDELSTEIN 7-X

Fusion Engineering and Design, 2005
WENDELSTEIN 7-X (W7-X) is a superconducting stellarator, which uses 50 non-planar coils for the main field and 20 planar coils to modify the magnetic configuration. The planar coils are cut into two differently shaped types and designed for 3 T on the plasma axis. A planar coil has an outer diameter of around 4 m.

Quality management for WENDELSTEIN 7-X

Fusion Engineering and Design, 2001
The WENDELSTEIN 7-X stellarator is the next step device in the stellarator line of IPP Garching and is being built in the new branch institute of IPP at Greifswald. Start of operation is scheduled for 2006. The W7-X project is presently the largest scientific project in Germany with a total spending of 300 MEU during the construction phase.

OPTEMIST: A neutral beam for measuring quasi-omnigenity in Wendelstein 7-X

Physics of Plasmas
A new neutral beamline (OPTEMIST) uniquely capable of exploring the predicted improvement of fast ion confinement in Wendelstein 7-X (W7-X), which comes with increasing plasma beta, is proposed.

Development of a compact bolometer camera concept for investigation of radiation asymmetries at Wendelstein 7-X.

Review of Scientific Instruments
Power exhaust is one of the central challenges in magnetically confined fusion plasmas. Radiative detachment can be employed to reduce particle and heat fluxes to the divertor target, mitigating divertor damage and erosion.

ICRF heating for Wendelstein 7-X

Fusion Engineering and Design, 2003
Abstract The stellarator Wendelstein 7-X is being built in Greifswald, Germany, by the Max-Planck-Institut fur Plasmaphysik. Initially, the heating system will consist of 10 MW ECRH and 4 MW ICRF heating (both cw) and 5 MW NBI (for 15 s every 3 min). ECRH is the principal heating method at a magnetic field of B =2.5 T.

The layout of the WENDELSTEIN 7-X magnet

Fusion Engineering and Design, 2001
Abstract The superconducting magnet system for the new stellarator WENDELSTEIN 7-X, to be located at Greifswald, Germany, consists of 50 non-planar and 20 planar large magnetic coils. A central support ring carries the coils and keeps them in their geometrical position.
