Neoclassical current and transport in auxiliary heated tokamaks

Description
A generalized Ohm's law is derived which includes the neoclassical Spitzer current, the Pfirsch-Schlueter current, the bootstrap current, and the fast-ion-induced current, including trapped-particle effects. Also, the additional neoclassical radial transport induced by the parallel momentum and heat flow inputs from the fast ion tail are determined. Detailed expressions for these transport coefficients are derived for a tokamak in the banana collisionality regime for a magnetic geometry of arbitrary aspect ratio with an elliptical plasma cross section. The magnitudes of the various possible effects are illustrated by calculations for high power auxiliary heating in JET. (author)
