Abstract

The argon spectra in the 2.3-3.4 nm region from the Jet tokamak on a single null divertor configuration is simulated. The spectra include lines from five ionization states, namely from Ar15+Li-like to Ar11+N-like ions. Collisional-radiative models are constructed for these five Ar ions, considering electron collisional excitation and radiative decay as the populating processes of the excited states. These models give photon emission coefficients for the emitted lines at electron density and temperature values corresponding to the experimental situations.
