Abstract

The extreme ultraviolet, double-dispersion, photographic spectrograph, Apollo Telescope Mount (ATM) Experiment S082B on Skylab is described. Novel features were the use of a predisperser grating with a ruling whose spacing varied approximately linearly with distance for the purpose of increasing the instrument speed by reducing the astigmatism and a photoelectric servo-system to stabilize to 1 sec of arc the solar image at various near-limb positions. The 970–3940-Å range was covered in two sections with effective λ/Δλ ≅ 30,000 from 1100 Å to 1970 Å. The spatial resolution was 2 × 60 solar sec of arc. During the Skylab mission 6400 exposures were made with the instrument pointed by an astronaut at selected and recorded solar positions.
