      abstract     = {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).},
