摘要：

Carbon and tungsten sputtering and transport in the DIII-D divertor is analyzed with the impurity transport codes REDEP and WBC. Analysis is carried out for a recent DiMES experiment in which a carbon sample with a tungsten marker in the center was exposed to six well controlled ELM-free plasma discharges. WBC analysis predicts a high rate of ionization of tungsten neutrals within the sheath and subsequent redeposition on the DiMES sample. Qualitative comparison of the tungsten redeposited flux agrees well with measurements. REDEP analysis of net carbon erosion shows good agreement with measured data on the outboard side of DiMES and poor agreement on the inboard side.
