scale length has been substituted for the density gradient scale
given in their paper following a comment made by Drake at the
1995 TTF Workshop[4]. Including diamagnetic and
elongation effects, the particle diffusivity is

The electron and ion thermal diffusivities are taken equal taken to be
an adjustable fraction of the particle diffusivity.
