The Extreme Ultraviolet Spectrograph

The Otraviolet solar radiation from 1000Å up to the atmospheric cutoff at 3000A is of great interest to solar physics. In order to record this spectral region in a form most advantageous to solar physics, the NRL Extreme Ultraviolet Spectrograph was designed with several major goals in mind. Among these were: the most complete spectral coverage possible, and the highest spectral, spatial, and temporal resolution possible. The total spectral coverage of this instrument is about 1000Å to 4000Å, which provides an overlap with ground based observations.
