3D fluid modelling of the edge plasma by means of a Monte Carlo technique

An extended version of the 3D Monte Carlo edge plasma transport code EMC3 including more complex physics is presented. The balance equations for mass, momentum and energies are formulated in a general conservation form suited for direct application of the Monte Carlo solving algorithm. The new extended version is applied to the planned W7-AS island divertor. First results of the investigations, which are focused on neutral pump-out efficiency, power load distribution on the plates and high recycling performance, are presented.
