EUV

This EUV instrument design is based on the heritage of four UCB “EURD-class” astrophysical space flight instruments (see top picture). These astrophysical instruments were designed for detecting similar ultra-violet wavelengths as the EUV instrument, but for signals that are an order of magnitude less bright than the Earth’s airglow. The interpretation of the EUV dayglow builds on the recent success of the DMSP-SSULI and RAIDS instruments.

The ICON EUV instrument (bottom) is based upon the UCB EURD astrophysical instruments (top; Edelstein et al., 2001).
