Wendelstein 7-X
Project
The corepiece of the experiment is the coil system composed of 50 non-planar,
superconducting magnetic field coils. They are to serve in Wendelstein 7-X
to demonstrate the essential stellarator property, steady-state operation.
The magnetic field cage produced is to confine a plasma with temperatures of up to 100 million degrees. Wendelstein 7-X should thus be capable of yielding convincing proof of the reactor properties of stellarators, without actually producing an energy-yielding plasma. As the properties of an ignited plasma in tokamaks can be largely extended to stellarators, the experiment can dispense with the use of the radioactive fuel, tritium, at great saving.
