Abstract

Magnetic field of helical symmetry in current free region is given by (17.1) and the rotational transform angle exists (refer (17.6) in Sect. 17.1). Therefore it is possible to confine plasmas without the plasma current. However toroidal stellarator looses the helical symmetry due to toroidal component of magnetic field. Neoclassical diffusion coefficient of plasma in helical field has the dependence of \(D_\mathrm{h} \propto 1/\nu \) in the intermediate collisional region (Sect. 17.3). Section 17.4 describes the experimental scaling laws of energy confinement times of stellarator (17.13)–(17.17). Section 17.5 describes designs of quasi-symmetric stellarator systems.
