The incidence of very low energy electrons on metal surfaces is mainly dictated by the phenomenon of quantum mechanical reflection at the metal interface. Low energy electron reflection is insignificant in higher energy regimes, where the…
Calculations of the heat flux carried by plasma to the wall of a magnetic fusion machine often assume that power flows only along the field lines, but this cannot be true in general. Instead, we treat the plasma as an anisotropic non-linear…
