Kα radiation is one of promising tools for plasma temperature diagnostics. In the previous study, the potential of Kα radiation from chlorine with partially ionized L-shell was discussed, and it is found that the Kα radiation is suitable for the plasma creation,
of which temperature is less than about 80 eV [1]. However, for lower temperature, which is a few tens electron-volts, Kα radiation from lower charge states may be available, and the electronic configurations of the emitter atoms have M-shell electrons. Such Kα spectra as that from chlorine with M-shell electrons overlap each other and the corresponding blue-shift by the M-shell ionization is at most a few electron-volts, which is quite small compared with that by L-shell ionization. The Kα transition energies and probabilities of chlorine with partially ionized M-shell are calculated using GRASP92 and RATIP [2,3], and unresolved spectral feature is obtained. In this paper, discussion will be devoted to basic properties of the Kα radiation for plasma diagnostics.
