Atomic Spectroscopy in Highly Ionised Plasmas
Observations of the JET tokamak are used to illustrate contrasting spectral emission from a range of plasma environments differing in temperature, density, interaction with boundary surfaces, dynamic state and excitation mechanisms. Some spectral features of diagnostic value are identified. Models based on collisional radiative theory are used to investigate these features. The generality of this approach to modelling the radiating properties of atoms in arbitrary dynamic plasmas is indicated.
