Coefficients of neoclassical transport in tokamaks and stellarators with non-axisymmetric equipotential surfaces mis-aligned with magnetic flux surfaces are derived for the 1/ν regime. In the general case, they are given ...

The collisionless confinement of all reflected particles with orbits that star within the inner half of the plasma of a stellarator with the poloidal direction of the contours of the magnetic field strenght B is shown ...
