Highly charged ions play a crucial role in magnetic fusion plasmas. These plasmas are
excellent sources for producing highly charged ions and copious amounts of radiation for …

We have recorded extreme ultraviolet spectra from W 11+ to W 15+ ions using a flat-field
spectrometer installed at the Shanghai high-temperature superconducting electron-beam …

A series of experiments on tungsten spectroscopy has been carried out in a Large Helical
Device with tungsten pellet injection to study the tungsten spectra. In particular …

Spectroscopy of highly-charged ions of tungsten has become a significant and highly visible
component of atomic physics research over the last decade. This development is influenced …

We have observed extreme ultraviolet (EUV) spectra from highly charged gadolinium and
neodymium ions in optically thin plasmas produced in the Large Helical Device at the …

The results obtained on the W VIII spectrum as well as on the isoelectronic spectra Lu V, Hf
VI, Ta VII, and Re IX in the VUV wavelength region are summarized with emphasis on the …

Tungsten will be used as a wall material in ITER and therefore will be present as an intrinsic
plasma impurity with the resulting emission having the potential to be used as a plasma …

We present recent results on the extreme ultraviolet (EUV) spectroscopy of highly charged
high Z ions in plasmas produced in the Large Helical Device (LHD) at the National Institute …

Two coaxial pellets with tungsten inserted into graphite carbon and polyethylene (PE) tubes
are compared for tungsten spectroscopic study in the Large Helical Device. The tungsten …

We report recent results of extreme ultraviolet (EUV) spectroscopy of highly charged heavy
ions in plasmas produced in the Large Helical Device (LHD). The LHD is an ideal source of …
