Book excerpt: High-resolution spectra of the elements Fe, Ni, Ge, Se, and Mo injected into the Princeton Large Torus tokamak were recorded by the 2-m Schwob- Fraenkel soft-x-ray multichannel spectrometer. Spectra were recorded every 50 msec during times before and after injection. The spectral lines of the injected element were very strong in the spectrum recorded immediately after injection, and the transitions in the injected elemented were easily distinguished spectrum recorded immediately after injection, and the transitions in the injected element were easily distinguished from the transitions in the intrinsic elements (C, O, Ti, Cr, Fe, and Ni). An accurate wavelength scale was established using well-known reference transitions in the intrinsic element. The spectra recorded just before injection were subtracted from the spectra recorded after injection, and the resulting spectrum was composed almost entirely of transitions from the injected element. A large number of delta n = 0 transitions between the ground and the first excited configurations in the Li I through K I isoelectronic sequences of the injected elements were identified in the wavelength region 60 to 345 A.
