The Diffuse X-Ray Spectrometer (DXS) experiment was built by the University of Wisconsin-Madison and flown as an attached payload in the January 1993 flight of Space Shuttle Endeavor (STS-54). The DXS's main scientific goal was to obtain spectra of the diffuse soft X-ray background.

Mission Characteristics

* Lifetime : January 13, 1993 - January 19, 1993
* Energy Range : 0.15 - 0.28 keV
* Payload :
    2 large area Bragg crystal spectrometers (43-84 Å)
    with 2.7 Å energy resolution
    and 15 ° (FWHM) angular resolution
* Science Highlights :
  • DXS obtained the first-ever high resolution spectra of the diffuse soft X-ray background in the energy band from 0.15 to 0.28 keV ( 43-84 Å).
* Archive : Raw data on FITS format.
