Identification of forbidden emission lines from highly ionized tungsten ions in VUV wavelength range in LHD for ITER edge plasma diagnostics

Magnetic-dipole (M1) lines of W29+~W39+ were successfully observed in the vacuum-ultraviolet (VUV) wavelength range of 500–900 Å in the Large Helical Device (LHD). Tungsten ions are distributed in the NBI-heated LHD plasma by injecting a pellet consisting of a small piece of tungsten metal wire encl...
