Mission Name: SkylabThe objective of this investigation was to obtain, through the availability of long exposure times, more information on the EUV and soft X-ray spectrum of the sun in the 10 to 200 A range. The instrument was a small grazing-incidence spectrograph with photographic recording. Use was made of a novel splitruled grating that combined 1200- and 2400-lines/mm rulings to double the spectral coverage of the instrument and to aid in the measurement of wavelengths and order sorting. Useful spectra were obtained, but the sensitivity of the instrument was greatly reduced, probably because of contamination resulting from leakage of the fluid used in the spacecraft cooling system. Details may be found in Applied Optics, vol. 16, no. 4, April 1977, pp. 893-903.
