The atomic structure and spectra of ten tungsten ions have been calculated using the Flexible Atomic Code. The calculations yield energy levels, radiative lifetimes, spectral line positions, transition probability rates, and oscillator strengths for the tungsten ions isoelectronic to germanium, W42+, through vanadium, W51+. Collisional-radiative models for high-temperature, low-density plasmas have been implemented to produce line emissivities for X-ray transitions in the 1-4 keV (3-12 angstrom) spectral interval. The Ge-like through V-like W ions are important in nuclear fusion research where their spectra may provide diagnostic information on magnetically confined plasmas. (C) 2013 Elsevier Inc.
