Theory of the Advanced Stellarator Reactor
The main features of an advanced stellarator reactor are the optimized coil system, the improved properties of plasma equilibrium with reduced Shafranov shift and a stability limit which is sufficient to meet the requirements of a commercial fusion reactor. To achieve these goals the magnetic surfaces must be properly shaped and the geodesic curvature of magnetic field lines must be minimized. This leads to small Pfirsch-Schlüter currents and reduced radial transport of particles. A systematic procedure to compute plasma equilibria with reduced Pfirsch-Schlüter currents has been established. Reduction of geodesic curvature not only reduces radial transport but also leads to a reduction of viscous damping, and thus facilitates the rotational spin-up of the plasma. The main feature of an advanced stellarator reactor are described.
