NSSDCA ID: 1975-057A-06
Mission Name: OSO 8This GSFC experiment was designed to determine the spectra of sources and the diffuse cosmic X-ray background in the energy range 2 to 60 keV, and to measure intensity variations and possible emission lines of discrete X-ray sources. Proportional chambers (multianode proportional counters) were used as detectors. One detector complement, consisting of a propane-neon-filled chamber and a xenon-methane-filled chamber (240 sq cm), was located behind a 5-deg collimator and oriented parallel to the spacecraft spin axis. A single-volume, argon-methane-filled chamber (75 sq cm) was located behind a 3-deg collimator and was offset slightly from antiparallel to the spin axis. A xenon-methane-filled chamber (270 sq cm) was located behind a 5-deg collimator and was oriented antiparallel to the spin axis. Data were accumulated in a buffer memory for 1-min intervals and the data from the offset detector were sectored in azimuth. For more information, see R. H. Becker et al., Ap. J., v. 209, p. L65, 1976.
