Thermal heat flux in a plasma for arbitrary collisionality

Abstract
The thermal heat flux along a uniform magnetic field due to a temperature gradient is calculated using a Monte Carlo solution to the Fokker–Planck equation. This numerical solution, which is computed for a particular electron temperature profile, is valid for arbitrary mean‐free‐path, λmfp. The calculated heat flux makes a smooth transition between the analytic expressions for the short and long λmfp limits.
