As the finalization of a hydrogen experiment towards the deuterium phase, the exploration of
the best performance of hydrogen plasma was intensively performed in the large helical …

The Large Helical Device (LHD) is one of the world's largest superconducting helical system
fusion-experiment devices. Since the start of experiments in 1998, it has expanded its …

The M-intrashell spectra from Co-like Yb 43+ through Na-like Yb 59+ ions produced in an
electron beam ion trap (EBIT) at the National Institute of Standards and Technology have …

Accurate extreme ultraviolet spectra of open N-shell neodymium (Nd) ions were recorded at
the electron beam ion trap facility of the National Institute of Standards and Technology. The …

We have systematically observed extreme ultraviolet (EUV) spectra from highly charged ions
of nine lanthanide elements with atomic numbers from 60–70 in optically thin plasmas …

Extreme ultraviolet (EUV) optical transitions of lanthanide highly charged ions have been
studied. The [Ni] 4 s 2 4 p–[Ni] 4 s 2 4 d and [Ni] 4 s 2 4 p–[Ni] 4 s 4 p 2 transition lines of …

Extreme ultraviolet (EUV) spectra of highly charged praseodymium (Pr) and neodymium
(Nd) ions have been investigated in optically thin high-temperature plasmas produced in the …

Plasma terminating events due to excess pellet fueling and impurity injection is studied in
the Large Helical Device, Wendelstein 7-X and TJ-II. Time scales for these events range …

Soft X-ray spectra from high Z rare-earth (lanthanide) elements have been systematically
observed in optically thin, high-temperature plasmas produced in the Large Helical Device …

Soft X-ray (SXR) spectra from hafnium and tantalum laser produced plasmas were recorded
in the 1–7 nm region using two Nd: YAG lasers with pulse lengths of 170 ps and 10 ns …
