The Wendelstein 7-X stellarator, now being built at the
Greifswald Branch of IPP, will test a magnetic field optimised to overcome
the difficulties of previous stellarator concepts. The quality of plasma
equilibrium and confinement will be comparable to that of a tokamak.
The predecessor, Wendelstein 7-AS (1988 - 2002), the first experiment of the new
generation of "Advanced Stellarators", was putting this concept
for an improved magnetic field to the first test. The further developed
follow-up device, Wendelstein 7-X, is now to demonstrate the reactor relevance
of the new stellarators.
