Abstract

For the purpose of a consistent treatment of tungsten impurity together with background plasma, coupling of the IMPGYRO and SOLPS codes has been undertaken. The fluid part of SOLPS transfers the background plasma data to the IMPGYRO kinetic impurity code, while IMPGYRO transfers the effect of tungsten impurities to SOLPS as particle, momentum and energy source/sink terms. An initial test calculation has been performed under a simple model for impurity generation. The impurity content in the system reaches a quasi-steady state in the coupled calculation. The temporal history of the simulation shows that an initial impurity generation results in a relatively large radiation loss and plasma cooling. The cooler plasma suppresses further impurity generation, leading to a quasi-steady state in the coupled calculation.
