“…These spectra were previously observed by Radtke et al [94,95] at the Berlin EBIT facility in the region 500-900 Å. The latter authors interpreted these spectra by collisional-radiative modeling using the Hebrew University Lawrence Livermore Atomic Code (HULLAC) [96].…”

This contribution reviews experimental and theoretical work on spectroscopy of tungsten published since the last critical compilation of the energy levels and spectral lines of highly ionized tungsten (Kramida and Shirai. At. Data Nucl. Data Tables, 95, 305 (2009)). Since then, 18 new experimental studies were published, which resulted in new identifications and (or) significantly improved wavelengths of spectral lines and energy levels of Li-like through As-like and Pm-like tungsten. A few tens of theoretical studies of tungsten spectra were published since 2008. A number of them report on high-precision calculations of energy levels, transition wavelengths, and radiative rates for tungsten spectra, such as neutral tungsten, Yb-like, Rh-like through Rb-like, Ag-like, Ga-like, Zn-like, Ni-like, Ca-like, Al-like, Mg-like, Na-like, Ne-like, B-like, Be-like, and Li-like. These developments are reviewed. Based on new experimental data, systematic errors are removed from some of the earlier measurements. Some new data are obtained by analyzing publications of other authors. Based on new published theoretical data, some old experimental results were confirmed and assessed. Revised and extended tables of energy levels and spectral lines of highly ionized tungsten are presented.

At. Data Nucl. Data Tables, 95, 305 (2009)). Depuis, 18 nouvelles études expérimentales ont été publiées, qui ont résulté en de nouvelles identifications et une amélioration significative des longueurs d'onde des raies et de l'énergie des niveaux des ions de tungstène allant du type Li jusqu'aux types As et Pm. Quelques dizaines études théoriques sur le tungstène ont été publiées depuis 2008. Certaines d'entre elles rapportent des calculs de haute précision de niveaux d'énergie, de longueurs d'onde de transitions et de taux radiatifs pour des spectres de tungstène, neutre et ionisé de types Yb, de Rh à Rb, Ag, Ga, Zn, Ni, Ca, Al, Mg, Na, Ne, B, Be et Li. Nous les passons en revue. Les mesures récentes ont permis d'éliminer certaines erreurs systématiques des mesures antérieures. Certains nouveaux résultats viennent de l'analyse de publications d'autres auteurs. Les nouveaux résultats théoriques ont permis de confirmer des résultats expérimentaux antérieurs dont l'identification restait incertaine. Nous présentons des tables nouvelles et étendues des niveaux d'énergie et des raies spectrales du tungstène hautement ionisé. [Traduit par la Rédaction]

We give a brief overview of our recent experimental and theoretical work involving highly charged tungsten ions in high-temperature magnetically confined plasmas. Our work includes X-ray and extreme ultraviolet spectroscopy, state-of-the-art structure calculations, the generation of dielectronic recombination rate coefficients, collisional-radiative spectral modeling and assessments of the atomic data need for X-ray diagnostics monitoring of the parameters of the core plasma of future tokamaks, such as ITER. We give examples of our recent results in these areas.

Magnetic dipole transitions in4dNconfigurations of tungsten ions

Magnetic dipole transitions between the levels of ground 4d N configurations of tungsten ions were analyzed by employing a large basis of interacting configurations. Previously introduced configuration interaction strength between two configurations was used to determine the configurations with the largest contribution to wave functions of atomic states for the considered configurations. Collisional-radiative modeling was performed for the levels of the ground configuration coupled through electric dipole transitions with 4p 5 4d N+1 and 4d N−1 4f configurations. New identification of some lines observed in the electron-beam ion trap plasma was proposed based on calculations in which wavelength convergence was reached.
