18. Stellarator optimisation: a brief review (I.3)

In this talk, I will give an overview of the history and present state of stellarator optimisation. Wendelstein 7-X was optimised for good magnetic flux surfaces, small Pfirsch-Schlüter and bootstrap currents, high MHD beta limit, and good neoclassical confinement. Most of these properties have already been confirmed experimentally, giving confidence that theory-based optimisation can pay off...

The stellarator is an attractive concept for magnetic confinement fusion reactors, as it offers some advantages over the tokamak. Whereas in tokamaks part of the magnetic field is produced by driving a large inductive current in the plasma, the magnetic field of the stellarator is generated by external coils, avoiding the risk of current-driven instabilities and making steady-state operation...
