Requirements for Deep Hard X-ray Survey

  • HX band (~5-600 keV) to overlap ABRIXAS and extend through 511 keV
  • Sensitivity ~0.0005 Crab flux to match and extend ROSAT and ABRIXAS and reach significant sample size (~10,000) of AGN full sky
  • All sky imaging each orbit to monitor source variability and provide transient alerts
  • Imaging resolution ~5arcmin (source positions <1arcmin) to avoid confusion limits
  • Spectral resolution E/dE ~ 50-100 to resolve continuum features and broad lines
