SOLPS modelling of W for ITER

The issue of tungsten contamination of the main plasma is an important one for ITER. In order to clarify some of the issues, SOLPS modelling has been performed for ITER with a species mix of D+T+He+Be+Ne+W: D+T as the primary hydrogenic species, He produced by fusion reactions, Be and W produced by sputtering from the main wall and targets, and Ne as a control parameter to increase the power radiated.
