The XMM payload


If the XMM spacecraft were made of glas, one could gain the above view of its payload. The X-ray telescopes, two with Reflection Grating Arrays, are visible at the lower left. At the right end of the assembly, the focal instruments are shown: The EPIC MOS cameras with their radiators (black/green "horns"), the radiator of the EPIC p-n camera (violet) and those of the (light blue) RGS receivers (in orange). The black box at the bottom of the bus is the outgassing device.
