A fully 3D self-consistent Monte Carlo code EMC3 (edge Monte Carlo 3B)
for modelling the plasma transport in island diverters has been devel
oped. In a first step. the code solves a simplified version of the 3D
time-independent plasma fluid equations. Coupled to the neutral transp
ort code EIRENE, the EMC3 code has been used to study the particle, en
ergy and neutral transport in W7-AS island divertor configurations. Fi
rst results are compared with data from different diagnostics (Langmui
r probes, H-alpha cameras and thermography).
