Variational Calculation of Neoclassical Transport Coefficients by Using Full Fokker-Planck Collision Operator

Abstract

The neoclassical transport coefficients from the plateau regime to the Pfirsch-Schlüter regime are calculated by using the linearized full Fokker-Planck collision operator. The inverse aspect ratio is assumed to be small and the mass ratio of the electron to the ion is much less than unity. The lowest-order terms of these ratios are retained in this calculation. The results obtained give correction to those of Rawls et al. who employed a model collision operator. In the Pfirsch-Schlüter regime, the results of this paper agree fairly well with those given by Hazeltine and Hinton.
