TL;DR: In this paper, a catalog of argon lines in support of new-generation X-ray observatories using the Lawrence Livermore electron beam ion traps is presented, which includes wavelength measurements with standard errors, relative intensities, and line assignments.

TL;DR: In this paper, a R=44.3m grazing-incidence grating spectrometer has been implemented on the Livermore electron beam ion traps for high-resolution measurements in the soft x-ray and extreme ultraviolet region spanning from below 10 up to 50

TL;DR: In this article, the emission spectra of iron in the extreme ultraviolet were obtained at an electron density of 5 × 1011 cm-3 at the Lawrence Livermore ion trap EBIT-II.

TL;DR: In this paper, high-resolution laboratory measurements of the emission from various ions of C, N, O, F, Ne, S, Ar, Fe, and Ni in the extreme ultraviolet wavelength band centered around the λ211 Fe XIV channel of the Atmospheric Imaging Assembly on the Solar Dynamics Observatory.

TL;DR: In this article, the authors compared the line emission of Fe VII-Fe X ions in the extreme-ultraviolet region below 140 A with the predictions from standard spectral models using the CHIANTI and MEKAL atomic databases and found that the atomic databases miss most of the line flux in this region.
