ESA SP-1273 X-ray Evolving - Universe Spectroscopy: The XEUS Instrument
This report was compiled by the XEUS Instrument Working Group (IWG) in two phases. The report covers three baseline instruments: a Wide-Field Imager (WFI) for deep-survey pointed observations, and two Narrow-Field Instruments (NFI1 and 2) for follow-up observations with high efficiency and high spectral resolution.
