XMM 10 Years in Orbit - ESA ESA’s X-ray observatory ready for the next decade

  1. 1. ESOC XMM-Newton ESA’s X-ray observatory ready for the next decade - Spacecraft Status and Perspectives Dr. Marcus G. F. Kirsch XMM-Newton Spacecraft Operations Manager European Space Agency (ESA) European Space Operations Centre (ESOC) January 2010 M.Kirsch, XMM-Newton M.Kirsch, XMM- European Space Operations Center Page 1
  2. 2. XMM-Newton ESOC observes objects that radiate in X-ray energies from 0.2-15 keV Xray-Multi-Mirror-Mission Cornerstone Mission of ESA’s Horizon 2000 Program M.Kirsch, XMM-Newton M.Kirsch, XMM- European Space Operations Center Page 2
  3. 3. the spacecraft ESOC • weight: 3.8 t, length: 10 m • squarish service module also carrying three 'mirrors modules' at its forward broader end • the focal plane assembly housing the X-ray cameras and detectors at its other extremity • 3 Wolter telescopes with 58 mirrors each • 2 solar panels with 16 metre span M.Kirsch, XMM-Newton M.Kirsch, XMM- European Space Operations Center Page 3

  5. 5. payload features ESOC • EPIC: – 3 independent CCD- cameras (2 MOS & 1 PN), observing simultaneously the same field – 3 different light filters for both camera types – different modes to accommodate brightness and timing • 2 Reflecting Grating Spectrometers – high-resolution spectroscopy of bright sources in the energy range from 0.3 to 2.1 keV • Optical Monitor – Extends the spectral coverage of XMM- Newton into the UV and optical – Six broadband filters – Two grisms, one in the UV and one in the optical M.Kirsch, XMM-Newton M.Kirsch, XMM- European Space Operations Center Page 5
  6. 6. detector technology: CCDs ESOC pn MOS RGS 12 back illuminated pn- 7 front illuminated Metal-Oxide 9 back illuminated CCDs, junction CCDs, each with : Semi-conductor CCDs, each with: each with: • 30 µm Si • 280 µm fully depleted Si • 100 µm Si • 384 lines • 600 lines • 1024 columns • 200 lines • 600 columns • Pixelsize: 27µm x 27µm • 64 columns • Pixelsize: 40µm x 40µm 40µ 40µ • pixelsize: 150 µm x 150 µm M.Kirsch, XMM-Newton M.Kirsch, XMM- European Space Operations Center Page 6
