Ionization and Recombination Rates for Argon Ions Ar xii–xvi from Time-Resolved Spectroscopy of Tokamak Plasmas

The effective ionization and recombination rate coefficients Ar xii–xvi were obtained by studying the modulation of line emission by sawtooth oscillations in the Texas Experimental tokamak (TEXT). Experimental data are matched with the simulation of argon ion emission by a one-dimensional code.
