TL;DR: The EUV Imaging Spectrometer (EIS) as mentioned in this paper is a two-element, normal incidence design with a backside-illuminated, thinned CCD, which has a significantly greater effective area than previous orbiting EUV spectrographs with typical active region 2 -5 s exposure times in the brightest lines.

TL;DR: The Coronal Diagnostic Spectrometer (CDS) as mentioned in this paper was designed to probe the solar atmosphere through the detection of spectral emission lines in the extreme ultraviolet wavelength range 150-800 A. By observing the intensities of selected lines and line profiles, the authors derived temperature, density, flow and abundance information for the plasmas in the solar ionosphere.
Journal ArticleDOI
