Abstract
We present synthetic spectra for light emission following charge exchange (CX) recombination for W64+ ions colliding with neutral atomic hydrogen at 100 keV/u and 500 keV/u, of relevance to the plasma diagnostics of the international experimental fusion device ITER now under construction. The spectra are calculated using a detailed collisional-radiative model for the W63+ ion that includes more than 6000 singly- and doubly-excited states and accounts for major physical processes in hot fusion plasmas. The CX cross sections into excited states are computed using the classical trajectory Monte Carlo method. A thorough analysis of the modifications to the spectra due to CX is presented.Citation
