ATOMIC AND MOLECULAR COLLISIONS IN THE PLASMA BOUNDARY
The objective of this paper is to provide an introduction to those aspects of atomic collision physics which underly the unavoidably generalised base of cross section data and scaling relationships which is currently employed in plasma modelling. Both experimental and theoretical methods are outlined and, where practicable, general trends in collisional behaviour are illustrated by ? examples of measured data. Atomic and molecular processes are considered on the basis of their particular relevance to the plasma edge region so that the discussion emphasises the properties of collisions in the regimes of low plasma temperature and low charge state of impurity ions. Particular attention is devoted to recycling of hydrogen atoms and molecules because of its powerful influence upon plasma properties adjacent to boundary surfaces.
