| 520 | _ | _ | |a The ERO-TEXTOR code is described in detail. The code solves the kinetic equations of impurities
in the scrape-off layer of a tokamak plasma in the vicinity of material surfaces like limiters
or divertors. A relaxation time ansatz in the traced impurity limit is chosen, taking the gyromotion
of the particles into account. Since the background plasma is slightly non-maxwellian at
the plasma edge higher order corrections (thermal [orces) to the relaxation time ansatz are also
considered. Background plasma parameters are calculated from a simple plasma model, i.e. the
one dimensional continuity and moment um equations are used to derive the local electron density,
the local fiow velo city and the pre-sheath and sheath electric fields. Since these calculations
are not done in a selfconsistent way, the measured values of electron density and temperature
are used as basic input to derive the dependency of these quantities. The regarded magnetic
topology is still straight and uniform.
Also detailed account is given to the plasma surface inter action and the erosion/deposition
processes. A linear differential equation model for multi species impact on a material surface
has been developed and is used in a discrete time step approximation.
External databases include the ionization rates for atomic species, molecular pro ces ses of methane
and silane molecules and the sputtering and refiection yields, which are taken from binary collisi
on calculation codes (e.g. TRIM) or from semi-empirical fits (e.g. the Bodhansky and Yamamura
fits). |
