X-ray powerful diagnostics for highly-ionized plasmas: He-like ions
D. Porquet, R. Mewe, J. S. Kaastra +2
The calculations of the ratios of the Helium-like ion X-ray lines from C V to Si XIII are revisited in order to apply the results to density, temperature and ionization process dia…

Helium-like triplet diagnostics
Jacques Dubau, Delphine Porquet
The 1s2-1s2l lines are the most intense He-like ions lines. They are used as spectroscopic diagnostics for solar active regions as well as for different laboratory plasmas. Nowaday…

Helium-like ions as powerful X-ray plasma diagnostics
D. Porquet, R. Mewe, A. J. J Raassen +2
We revisited the calculations of the ratios of the Helium-like ion ``triplet'' (resonance, intercombination, and forbidden lines) for Z=6 to 14 (C V, N VI, O VII, Ne IX, Mg XI, Si…
