 Abstract: The ambipolar radial electric field and ion heat flux in the presence of this field are studied using Monte Carlo guiding centre orbit following code ASCOT. These are studied as a function of temperature gradient in different collisionality regimes. Good agreement with the analytic theory is found for heat fluxes in plateau and banana regimes but in Pfirsch- Schluter regime sub-neoclassical heat flux is found for steep temperature gradients. For radial electric field, deviations from analytic theory are significant.
