| Outline of Final Research Achievements |
A developed high-Z impurity pellet is injected in LHD device and line emissions from such impurities are sufficiently obtained. Impurity spectra are measured with visible, VUV and EUV spectrometers in details. The unresolved transition array (UTA) is successfully observed in EUV range. The result is analyzed with developed C-R model and a good agreement is obtained. Line emissions from low-ionized tungsten, e.g. WVI, are observed for the first time in VUV range. Magnetic dipole forbidden line (M1) in visible range is also observed from tungsten ions for the first time in fusion plasmas. The wavelength is compared with theoretical values. A clear difference is observed between the experiment and theory. The result requests further improvement in the atomic structure model.
