Description

A collisional-radiative model for tungsten highly charged ions is developed with atomic data calculated by HULLAC code. The present model is validated by comparing Extreme-Ultra-Violet spectra measured by a compact electron-beam-ion-trap (CoBIT). Tungsten spectra in Large Helical Device (LHD) core plasmas are analyzed with the present model and it is applied to tungsten ion measurements at LHD. (author)
