Microscopic theory of electron absorption by plasma-facing surfaces

11 Jul 2016 Bronold Franz X. Fehske Holger

We describe a method for calculating the probability with which the wall of a plasma absorbs an electron at low energy. The method, based on an invariant embedding principle, expresses the electron absorption probability as the probability for transmission through the wall's long-range surface potential times the probability to stay inside the wall despite of internal backscattering...
