The soft x-ray spectra of heavy element plasmas are frequently dominated by unresolved transition array (UTA) emission. We describe the spectral evolution of an intense UTA under optically thin conditions in platinum plasmas. The UTA was observed t

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 co
