Stellarator
 scroll 
Experimental arrangement for controlled nuclear fusion.
In a stellarator, the screw-like twisting of field lines around the
torus centre is generated by external coils. In contrast to the Tokamak,
a stellarator does not need a direct-axis flow component in the plasma.
The stellarator can therefore function statically in principle. In a
stellarator, the magnetic field cage is formed by a single coil system.
The abandonment of the annular plasma flow signifies, however, the abandonment
of the axial symmetry existing in Tokamaks; plasma and magnetic coils
have a more complicated shape. For a fusion power plant, the stellarators
could provide a technically simpler solution than Tokamaks. This issue
cannot be answered theoretically; it must be decided by experiments
which is the aim of the WENDELSTEIN experiments of the Max Planck Institute
for Plasma Physics.
