Abstract
The purpose of this paper is to present the first steps towards coupling the IMPGYRO and SOLPS codes for a self-consistent treatment of tungsten as an impurity together with a background plasma. The kinetic IMPGYRO code transfers the effect of tungsten impurities to the SOLPS fluid code, as source / sink terms. As the first step of the coupling, we have implemented in the IMPGYRO code the calculation of the following source / sink terms: 1) electron particle source / sink due to tungsten ionization / recombination, 2) electron heat sink by tungsten radiation cooling, 3) background plasma ion momentum source / sink due to Coulomb collisions with tungsten ions, and 4) background plasma ion heat source / sink due to Coulomb collisions with tungsten ions. Test calculations have been done to check these source terms with a fixed background plasma from the SOLPS code and reasonable results have been obtained. In addition, some technical improvements have been done concerning the data transfer between the SOLPS and IMPGYRO codes on a Linux-cluster system under MPI environment. Based on this, the code is ready for full coupled calculations.
