The X-ray Multi-Mirror Mission (XMM-Newton)


XMM Newton

The X-ray Multi-Mirror Mission (XMM-Newton) was launched by Ariane 504 on December 10 1999. XMM-Newton is ESA&rsuoq;s second cornerstone of the Horizon 2000 Science Programme. It carries high thoughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.

Mission Characteristics

Lifetime
December 1999–present (nominal 10 year mission)
Special Features
  • Very large collecting area
  • Simultanenous X-ray and optical observations
  • Three Wolter Type I grazing incidence gold-coated imaging X-ray telescopes

Payload

European Photon Imaging Camera Metal-Oxide-Silicon (EPIC-MOS)

Energy Range
0.1–15 keV
Effective Area
922 cm2 at 1 keV
Field of View
33′ × 33′
Angular Resolution
6″ FWHM
Energy Resolution
∼20–50 (E/ΔE)
There are two EPIC-MOS units, mounted under each of the two telescopes. Each unit consists of an array of 7 CCDs, each 600 × 600 pixels.

European Photon Imaging Camera PN (EPIC-PN)

Energy Range
0.1–15 keV
Effective Area
1227 cm2 at 1 keV
Field of View
27.5′ × 27.5′
Spectral Resolution
∼20–50 (E/ΔE)
A single instrument with an array of 12 CCDs (12 × 200 pixels each) used for spectro-imaging

Reflection Grating Spectrometer

Energy Range
0.35–2.5 keV
Effective Area
185 cm2 at 1 keV
Field of View
5′
Spectral Resolution
200–800 (E/ΔE)
The gratings, mounted under each of the two telescopes, deflect about 50% of the X-ray light onto an array of 9 EPIC-MOS CCD detectors. Line density is ∼645 lines mm-1 at center.

Optical Monitor (OM)

Co-aligned 30 cm optical/UV telescope with a ∼17′ field of view and ∼1″ spatial resolution
