Wendelstein 7-AS (1988 - 2002)
Project
The Wendelstein 7-AS stellarator experiment, which was operated at IPP in Garching
from 1988 till 2002, belonged to the further developed generation of "Advanced
Stellarators": Wendelstein 7-AS was distinguished from conventional
stellarators by its re-computed, physically improved magnetic field generated
by likewise innovative, specially shaped coils.
Objectives
Objectives
- investigation of a net-current-free plasma
- demonstration of improved equilibrium and transport behaviour due to the improved magnetic field structure
- investigation of the stability limits of the plasma
- heating of the plasma by various heating methods
