Research Abstract

In this study, using the EUV and visible spectrometer installed in Electron Beam Ion Traps (EIBT), we observed the emission spectra of highly charged ions. We succeeded in reproducing the EUV spectrum of tungsten impurity pellets LHD plasma by scanning the electron beam energy in the present device. Based on these results, we will proceed with the collection of basic data useful for nuclear fusion.
