Integral

 2002-048A

---

The 3600 kg Integral (International Gamma Ray Astrophysics Lab) satellite is scheduled for launch in 2002 Apr by Proton. The joint ESA/NASA/IKI project is ESA's M2 mission. It will be placed in a 48000 x 115000 km x 51.6 deg orbit. Prime contractor is Alenia Spazio/Torino, and the service module (SVM) uses the XMM design.

The IBIS coded mask telescope has 12' resolution with 1' position accuracy. There are two detectors at IBIS' focus, ISGRI and PICsIT, with approx dE/E = 0.08, optimized at different energy ranges. The detectors are one below the other, so they both have the same field of view. ISGRI has a 2 x 4 array of 32 x 64 pixel detectors, making a total of 128 x 128 pixels. PICsIT is 64 x 64 pixels. A central 9x9 degree FOV can be fully imaged, with partial information on a 29x29 deg FOV; the actual FOV is larger due to “dithering”. The JEM-X instrument has two smaller 0.535m coded mask telescopes; the 0.7m SPI telescope and the OMC optical monitor are coaligned with JEM-X and IBIS.
