| Research Abstract |
In terms of the development of short wavelength light source and the understanding of impurity behaviors in fusion plasmas, we have observed extreme ultraviolet spectra from highly charged high Z ions of lanthanides, tungsten, bismuth, etc. in optically thin, high temperature plasmas produced in the Large Helical Device (LHD). Spectral feature has drastically changed depending on the electron temperature because of the change in ion abundance. Experimental database has been systematically developed in a wide range of Z. The emission mechanism as well as the dependences on Z and electron temperature has been well understood through the identifications of discrete spectral lines and the comparative analyses with theoretical calculations.
