Survey of EUV Impurity Line Spectra and EUV Bremsstrahlung Continuum in LHD
Plasma and Fusion Research, 2011 Radial profiles of impurity spectral line emissions in extreme ultraviolet (EUV) range (60-400 A) are surveyed for impurity seeded discharges in Large Helical Device (LHD). The line emissions from light impurities such as helium, carbon and neon are located in the edge ergodic layer (1.0 ≤ ρ ≤ 1.2) except for CV and CVI, which are located in region of ...

The Diagnostics of the κ-Distributions from EUV Spectra
Solar Physics, 2010The EUV lines suitable to diagnose possible κ-distributions in the solar corona are examined. A set of synthetic spectra for various values of the κ-parameter, characterizing the non-thermal κ-distributions, electron densities, and the mean energy of the distributions are calculated in the spectral range corresponding to the Hinode/EIS and Coronas-F ...

A study of EUV spectra in the fifth period
Journal of Physics B: Atomic and Molecular Physics, 1972Spectrograms of Ru, Rh, Pd, and Ag in the 50-500 AA region were obtained using a 3 electrode vacuum spark (3ES) as a source and a 2m grazing incidence spectrometer. Spectra from the transition arrays of 4p5-4p45s in the isoelectronic sequence (IS) of Br I, 4p6-4p54d, 5d, 6d, 5s, 6s, 7s in the IS of Kr I, 4d-4f, 5f, 5p, 6p, in the IS of Rb I, were ...

EUV spectra of Mo XIV to Mo XXIX
Physics Letters, Section A: General, Atomic and Solid State Physics, 1980Abstract Observations of the EUV spectra of Mo XIV to Mo XXIX have been made in the wavelength region from 5 to 50 nm by foil excitation of 22 to 200 MeV Mo ion beams. The results are compared with spectra observed in tokamak plasmas and light sources and with theoretical predictions.

The Interpretation of EUV Spectra of Sunspots
International Astronomical Union Colloquium, 1983We report here on EUV observations of a sunspot observed by the Harvard instrument on Skylab. The observational data used here have been presented in a previous paper by Noyes et al. (1982), in which line identifications and intensities for the wavelength region 350 – 1350 A were given.

Analyses of GOES-13 EUV 5-channel spectra
Proceedings of SPIE, 2007ABSTRACT The first of the Geo-stationary Operational Environmental Satellites (GOES) NO/P series, built by Boeing Satellite Systems was launched on May 24, 2006. The spacecraft, now on -orbit and referred as GOES-13, carries an Earth Imager, Sounder and a collection of space environment monitors (SEM) including, for the first time, a solar Extreme ...

Voyager EUV solar spectra during 1981–1993
Solar Physics, 1994EUV solar observations have been obtained with the Voyager 1 and Voyager 2 Ultraviolet Spectrometers since 1981. The two instruments, which are now at a distance of more than 40 AU, cover the wavelength range between 500 and 1700 A at a resolution of about 30 A.

Continuum Absorption in the Solar EUV Spectra
Astrophysics and Space Science, 1986It has been shown from ground-based and space observations that the lower corona of the Sun contains a significant amount of cool chromospheric material in highly inhomogeneous structures, such as spicules, dark mottles, and fibrils. Therefore, some interactions between the cool and the hot material have been found in optical and ultraviolet ...
