The soft X-ray lines emitted by highly ionized impurities are one of the most prominent spectral features of today’s tokamaks. In fact the hydrogen isotope plasmas produced in these devices attain temperature values ranging from about one to several keV. A great deal of information about the plasma conditions can be drawn, in particular, from the highly resolved spectra of medium-Z ions which are very rich in satellites excited via dielectronic recombination and innner shell excitation (Dubau and Volontè 1980, Bitter et al. 1979).
