The XUV spectroheliometer on SMMThe XUV spectroheliometer for the Solar Maximum Mission (SMM) is described. This instrument is a grazing-incidence polychromatic photoelectric spectrometer illuminated by a grazing-incidence telescope mirror. The wavelength range is 20-1336 A, the spectral resolution is between 0.1 and 0.3 A, and the spatial resolution is 4 arcsec. Simultaneous spectroheliograms in twelve spectral lines are obtained by rastering the instrument at variable rates. The scientific objectives and the mission operations concept are also described.
