Laboratory Measurements of High‐ n Iron L‐Shell X‐Ray Lines

Abstract

We present a comprehensive wavelength survey of Fe L-shell X-ray lines between 7 and 11 Å measured using flat crystal spectrometers and the EBIT-1 and EBIT-II electron beam ion traps at the Lawrence Livermore National Laboratory. This survey includes all significant emission lines produced by over 200 n → 2 transitions in Fe XVIII - XXIV, with n = 4-10. The identification and assignment of transitions are made with the help of detailed theoretical modeling using the Flexible Atomic Code (FAC). © 2007. The American Astronomical Society.
