A general solution of the ripple-averaged kinetic equation (GSRAKE)
A general solution of the ripple-averaged kinetic equation, GSRAKE, is presented and used to investigate neoclassical transport in the model magnetic field of a simple stellarator. Separate but fully self-consistent treatments of both localised and non-localised particles are provided; the interaction between these two classes of particles is calculated using appropriate physical boundary conditions. All drift terms present within the framework of the ripple-averaged theory are included. A detailed comparison of results with those of the FLOCS code is undertaken and estimates of neoclassical transport coefficients obtained from several codes are also presented. Good agreement of results is found in all of these comparisons, GSRAKE requiring but a tiny fraction of the computational time necessary for the other codes.
