プラズマ原子·分子過程の展望 4. 輸送コード 4.2 The Atomic Physics of Impurity Transport in Fusion Devices

抄録

Study of the movement of plasma and impurity species in fusion devices depends strongly on theoretical/computational models. These are built from fluid or kinetic pictures which depend on the coupling between species at the atomic level as well as on gross magnetohydrodynamic fields. With the fusion goal almost within reach, these models are now designed to be accurate representations of real machine geometries, sources and conditions and are tied to spectroscopic, particle and other experimental measurements. In this article some examples are discussed in which the atomic and transport processes are closely linked and where recent measurements have clarified behaviour.
