Spectra of highly-ionized atoms for the diagnostics of the new generation of Tokamaks
Abstract
In the new large Tokamaks the central electron temperature is expected to reach 5 to 10 keV with densities in the neighborhood of 10 to the 14th power/cu cm. For appropriate diagnostics under such conditions the n=2 shells are considered from germanium to molybdenum, with particular emphasis on long-wavelength lines in the ground configurations of these atoms. These elements of course also emit light on the n=3 and n=4 configurations, which are to a large extent already known from past experiments, and will be useful for near peripheral diagnostics. In addition to the transitions within the ground configurations there are certain intercombination lines for some of the ionization states in the relatively uncrowded part of the spectra, as well as some lines of the neon-like configurations, that are of diagnostic interest.
