 note = {0000-0003-4139-7721, Tungsten spectra in visible, vacuum ultra-violet (VUV) and extreme ultra-violet (EUV) wavelength ranges have been studied in LHD, EAST and HL-2A toroidal devices for magnetic-confinement fusion research. Tungsten spectra from low-ionized tungsten ions are observed in VUV and EUV ranges, e.g. W VI at 605.926 Å and W VII at 216.219 Å and 261.387 Å, and Doppler temperature of the W5+ ion and edge tungsten influx rate of the W6+ ion are analyzed. Ionization stages of unresolved transition array mainly consisting of W24+-W33+ ions at 15–70 Å are determined at each small wavelength interval of 0.1 Å based on radial profile measurement. The density profile is analyzed for W24+ and W27+ ions in addition to highly ionized ions, e.g. W44+ and W45+. Several magnetic dipole forbidden lines are observed, e.g. W XXVII and W XXVIII, and the density profile is also analyzed for W27+ ions. Contributions are made on tungsten diagnostics for fusion research through the present studies.},
