Abstract The high-velocity tail of the electron distribution has been calculated by solving the high-velocity form of the Landau equation for a thermal structure representative of a flaring coronal loop. These calculations show an enhancement of the tail population above Maxwellian for electrons moving down the temperature gradient. In the transition region they also show enhancement at higher velocities for electrons with all pitch angles, except those streaming up the gradient within ≤ 45° of the vertical direction. These results have been used to test the reliability of the BGK approximation. The comparison shows that the BGK technique can estimate contributions to the heat flux from the high-energy tail, to within an order of magnitude.
