Reduced model for the Scrape-Off Layer

Participants: L. Navoret, M. Mehrenberger, P. Ghendrih (CEA Cadarache)

In this work, we consider a one-dimensional model for describing the two-species plasma dynamics in the scrape-off layer. This region is defined as the transition between the core of the plasma and the edge and is located around the first non-closed magnetic field line. The electron and ion distribution functions satisfy a Vlasov-Poisson system with source and absorption terms and a non-homogeneous equilibrium is expected to develop. A high-order semi-Lagrangian scheme has been implemented to correctly capture such a dynamics.
