We report on emission spectra of iron in the extreme ultraviolet recorded at an electron density of ∼5x10¹¹ cm^–3 at the Lawrence Livermore electron beam ion trap EBIT-II. We present a summary of observed emission lines, including wavelengths and emission intensities. We also illustrate our technique for isolating pure charge states of the desired ion and present spectra of pure Fe VII-Fe X. Our measurements add a large number of newly identified lines to existing line lists in the extreme-ultraviolet region, 60-140 Å. While many of these lines are quite weak, they add up to a significant flux that can seriously affect interpretations of global fitting models, especially when applied to stars with material at the appropriate temperatures, such as Procyon, α Cen, and the Sun.
