Emission lines of iron in the 150–250 Å region on National Spherical Torus Experiment

Abstract

We measured iron emission from the National Spherical Tokamak Experiment. We focused our attention on several band pass regions of the Solar Dynamics Observatory's Atmospheric Imaging Assembly. We found that all significant iron emission in the 171, 193 and 211 Å band pass regions are accounted for by the CHIANTI atomic database, although some strong emission lines of carbon are present that may complicate interpretation of solar data if not taken into account.
