Title:	Kalpha radiation from low charge chlorine heated by an ion beam for plasma diagnostics
Abstract:	Kalpha radiation is one of promising tools for plasma temperature diagnostics. In the previous study, the potential of Kalpha radiation from chlorine with partially ionized L- shell was discussed, and it is found that the Kalpha radiation is suitable for the plasma diagnostics, of which temperature is less than about 80 eV [1]. However, for lower temperature, which is a few tens electron-volts, Kalpha radiation from lower charge states may be available, and the electronic configurations of the emitter atoms have M- shell electrons. Such Kalpha 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 Kalpha 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 Kalpha radiation for plasma diagnostics. References: [1] T. Kawamura et al., Laser Part. Beams 24, pp.261-267(2006). [2] F. A.
