As the first step in the modelling of the plasma-wall interaction of t
he proposed dynamic ergodic, divertor (DED) of TEXTOR-94, the topology
of the magnetic field lines of the divertor is analysed. Despite the
strong ergodization, the magnetic field lines intersecting the wall in
one poloidal turn form continuous sets. These sets are visualized by
a two dimensional (2-D) imaging technique; the field lines are traced
one poloidal turn clockwise and counter-clockwise from the outer midpl
ane, marking those lines intersecting the wall. An overlay of the mark
ed starting points defines areas with the properties of a scrape-off l
ayer (SOL) and areas with field lines ending on one side in the ergodi
c layer and one side on the wall. The edge plasma can be described by
a 2-D model; the model treats part of the plasma as that of a conventi
onal SOL and another part as that with 'half open' field lines connect
ing the divertor target plate with the ergodic layer. Calculations of
the power flux distribution in the DED near field divertor are present
