Plasma-Materials Interactions and Impurity Control in Magnetically Confined Thermonuclear Fusion Machines ... 

This chapter restricts itself to the set of problems associated with plasma materials interaction which in some aspects, are related to plasma chemistry in a broader sense. 

As has already been pointed out, the plasma materials interaction represents one of many serious problems which have to be solved if controlled fusion based on Toka-maks is to become an adequate energy source. 

The previous discussion has shown that plasma impurities present a complex set of problems whose solution is crucial to the successful operation of fusion reactors. The many and often subtle factors that govern plasma-materials interactions are still only partially understood. Consequently, the methods used today to control impurities are to a degree empirical in nature and cannot yet be precisely defined. It is likely that in the end a variety of approaches will be used to keep plasma impurities at minimal levels. The techniques are conveniently divided into divertor and non-divertor methods. The latter depend on modifications of one sort or another of the composition or structure of the surfaces facing the plasma. As will be seen in Sect. 6.5., meth-...
