Abstract

We report a method in EBIT spectral analysis that reduces signal from contaminant lines of 1 known or unknown origin. We utilize similar ion charge distributions of heavy highly charged ions 2 that create similar potentials for lighter contaminating background elements. Extreme ultraviolet 3 spectra of Na-like and Mg-like Os and Ir were recorded at the National Institute of Standards and 4 Technology using a grazing incidence spectrometer. First order approximations to ion distributions 5 are also presented to demonstrate differences between impurity elements with and without heavy 6 ions present.
