The Wendelstein 7-AS stellarator was in operation at Garching from 1988 till 2002.
The Wendelstein 7-AS stellarator experiment was a member of the advanced stellarator generation developed at IPP. It subjected basic elements of stellarator optimisation to first tests. This served as basis for successor Wendelstein 7-X, at IPP’s Greifswald branch.
Wendelstein 7-AS differed from previous stellarators by virtue of a newly calculated, physically improved magnetic field that was likewise generated by novel, three-dimensionally distorted coils.
