The Wendelstein 7-AS (Advanced Stellarator) was located at the [http://www.ipp.mpg.de/ Max Planck Institut für Plasmaphysik (IPP)] in Garching, Germany. | |||
The denomination 'advanced' refers to the use of [[Modular coil|modular]] (non-planar) coils. | |||
It has been operated from 1988 to July, 2002. <ref>M. Hirsch, J. Baldzuhn, C. Beidler, et al., ''Major results from the stellarator Wendelstein 7-AS'', [[doi:10.1088/0741-3335/50/5/053001|Plasma Phys. Control. Fusion '''50''' (2008) 053001]]</ref> | |||
Its successor is the [[W7-X]] stellarator. | |||
