Abstract
Electron-impact excitation of argon ions is a vital component in the modelling of fusion tokamak experiments. Currently the available electron-impact excitation rates for the argon isonuclear sequence are a collection of isolated calculations carried out within various theoretical scattering models. With the development of our parallel suite of Breit–Pauli codes and the accessibility of massively parallel architectures, there was the opportunity to calculate the entire argon isonuclear sequence and provide a single, comprehensive and complete excitation data set. These data will subsequently be archived as Maxwellian averaged rate coefficients. We report on Breit–Pauli R-matrix electron-impact excitation calculations that have been performed for Ar3+, Ar4+, Ar5+, Ar7+, Ar8+, Ar10+, Ar11+, Ar12+, Ar13+, Ar14+ and Ar17+. Together with existing R-matrix calculations, this completes the generation of excitation data for the argon isonuclear sequence.
