Abstract :
The vacuum ultraviolet spectra of highly charged tungsten ions W25+–W63+ are calculated with the collisional-radiative modeling. The synthesized spectra of total tungsten ions are obtained using the fractional abundance of the ionization equilibrium. The synthesized spectra explain the vacuum ultraviolet spectra observed for JT-60U plasmas at central electron temperatures of 6 and 10 keV.
