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‐Schlüter regime sub‐neoclassical heat flux is found for steep temperature gradients. For radial electric field, deviations from analytic theory are significant.
