The SODART experiment onboard the Spectrum Röntgen-Gamma satellite

• SPECTRUM RÖNTGEN-GAMMA (SRG) is an international high-energy space mission under IKI (Russia) leadership planned for launch 2003 into a highly excentric orbit of 200.000 km apogee to measure a wide spectrum of cosmic radiation from UV (TAUVEX, FUVITA) over X-ray (SODART, JET-X, MOXE) to soft gamma-ray (MART-LIME, SPIN) energies.

  
  

• SODART is a high-throughput multi-mirror X-ray twin TELESCOPE of 8m focal length with changeable detectors on slides (HEPC/LEPC, KFRD, solid-state SIXA, and polarimeter SXRP) for energies between 0.1 and 20 keV. In the left telescope (open side window) it contains the spectrometer OXS.

  
  

• OXS is an objective crystal spectrometer with very high resolving power, where the AIP is involved. A detailed DESCRIPTION of OXS and several SOFTWARE packages for SODART/OXS observations are available.
