The Tungsten Project: A complete set of isonuclear dielectronic recombination rate coefficients for use in magnetically confined fusion plasmas

A requirement of collisional-radiative models of magnetic fusion plasmas is that a detailed set of atomic data for the constituent ions is included. For the upcoming fusion reactor ITER, this is a difficult requirement to fulfill as the divertor will be made of tungsten. For this metal, partial final-state resolved dielectronic recombination (DR) rate coefficients are required. For this purpose we created The Tungsten Project. We give a brief overview of the methods used, and present results for a revised steady-state ionization balance.
