AB: The Extreme Ultraviolet Normal-Incidence Spectrograph (EUNIS) is a sounding rocket experiment that will investigate the energetics of the solar corona and hotter transition region through high-resolution imaging spectroscopy with a rapid (2 s) cadence. EUNIS features independent optical systems to record spatially co-aligned spectra over the two bandpasses 170--205 Å and 300--370 Å simultaneously. All the components in the detection chain have been characterized, including multilayer telescope mirrors, lithographic slits, multilayer diffraction gratings, microchannel plate intensifiers, and active pixel sensors. The results demonstrate that EUNIS is the most sensitive solar EUV spectrograph in existence. Its first flight is scheduled for 2005 August.
