Neutral gas transport in fusion devices : Atomic and surface data aspects
The status of atomic and surface data as presently implemented in neutral gas transport models is reviewed. Recent extensions of neutral gas models are discussed, such as the incorporation of elastic atom-ion collisions. It is shown that transport coefficients for a hydrodynamic description of transport can be evaluated by averaging the rate coefficients in the kinetic equations. Data relevant to charge exchange collision processes, elastic neutral-ion collisions, collisional radiative ionisation and recombination are discussed, and an existing surface reflection database is described.
