Abstract

The INTEGRAL observatory, due for launch in 2001, will address the fine spectroscopy (2 keV FWHM 1 MeV) and accurate imaging (12 arcminute FWHM) of celestial gamma-ray sources in the important 15 keV to 10 MeV energy range. The fine spectroscopy will permit spectral features to be uniquely identified and line profiles to be determined for in-depth studies of the source regions. Fine imaging will permit the accurate location and hence identification of the sources with counterparts at other wavelengths. ESA has completed the selection process for the scientific instruments to be flown on INTEGRAL, the data center and mission scientists, and the project is in its phase B development stage. The two main instruments onboard are a spectrometer which employs high-spectral-resolution germanium detectors and an imager which employs high- spatial-resolution arrays of cadmium telluride and cesium iodide detectors. Optical and x-ray monitors complete the scientific payload.
