A multiple timescale expansion and anomalous plasma transport

At the last meeting we had presented the application of a multiple timescale derivative expansion to the dimensionless Fokker-Planck equation. In continuation of this work, the zero order Fokker-Planck collision operator appearing in the second-order equation is integrated and the first three velocity moments are performed leading to the transport equations on the collision timescale. The transport processes resulting from the finite zero-order fluid velocities and from the MHD fluctuation spectrum turn out to be one order larger than those of classical or neoclassical transport.
