Code/Code comparision of impurity transport in EMC3 and DIVIMP

The 3D scrape off layer plasma code EMC3-eirene was recently augmented by a new “kinetic” trace impurity transport model that takes the inertia of the impurities into account and is thus better suited for heavy impurities like W than the original impurity transport module. To test the new “kinetic” a code/code benchmark with DIVIMP, which includes the same physics, was performed. This presentation will first introduce the kinetic impurity transport model, then outline the differences between EM3 and DIVIMP and finally show the comparison of Be and W transport calculated for a selected toroidally symmetric ITER background plasma case that could be handled by both codes.
