摘要：

The two-dimensional Monte Carlo code DIVIMP is used as an interpretative tool for the analysis of spectroscopic measurements in the edge and the divertor plasma of ASDEX-Upgrade. For a series of standard Ohmic discharges, the spectral lines of C+ and C2+ ions, recorded by two spectrometers viewing perpendicular and tangential to the outer divertor plates, were modelled. The simulations show that carbon production by physical sputtering alone is not sufficient to explain the observed signals. Further sources, possibly caused by chemical erosion processes must be taken into account.
