Suzaku (aka Astro-E2)


Astro-E
Astro-E2 was successfully launched on 12:30 pm JST on July 10, 2005 from the Uchinoura Space Center (USC) in Japan. Soon after launch, the mission was renamed Suzaku.
Suzaku is the re-build of Astro-E, which was unfortunately lost during launch (10 February 2000). Suzaku (as Astro-E) has been developed at the Japanese Institute of Space and Astronautical Science (ISAS) in collaboration with the US. This is Japan's fifth X-ray astronomy mission. Suzaku is the first satellite that carries a new type of X-ray spectrometer, the X-ray micro-calorimeter, which provides unprecedented energy resolution compared to non-dispersive instruments.

Mission Characteristics

* Lifetime : 10 July 2005 - 2 September 2015
* Energy Range : 0.2-600 keV
* Special Features : First X-ray micro-calorimeter in space
* Payload :
  • Five nested conical thin-foil grazing incidence telescopes (XRT),
    with a angular resolution of ~2 ´ (HPD); all gold-coated.
    Focal lenght : 4.75m (XRT-I, 4 units); 4.5m (XRT-S, 1 unit)
    At the focus of each telescope there is one of the following detectors :

    • X-ray Spectrometer (XRS; 0.3-12 keV; one unit)
      An X-ray micro-calorimeter composite of 32 pixels at the foci of the XRT-S.
      Eff Area 190 cm2 @ 1.5keV
      Energy resolution ~6.5 eV (FWHM) at 6 keV
      FOV 2.9´ X 2.9´

    • X-ray Imaging Spectrometer (XIS; 0.2-12 keV; four units)
      Each unit is a 1024 X 1024 pixel CCD detector at the foci of one XRT-I.
      Three CCDs are front illuminated (FI), one is back illuminated (BI)
      Eff. area 340 cm2 (FI) and 390 cm2 (BI) @ 1.5 keV
      Energy resolution 130 eV at 6 keV
      FOV 18´ X 18´

  • Hard X-ray Detector (HXD; 10-600 keV)
    GSO crystal scintillator (> 30 keV) & silicon PIN diodes (< 60 keV)
    Eff. area ~145 cm2 @ ~15 keV (PIN) , 315cm 2 at 2 @ ~100 keV (GSO)
    Energy resolution 3 keV FWHM, 7.6/(E MeV) 0.5 % FWHM
    FOV 34´ X 34´ < 100 keV and 4.5° X 4.5° > 100 keV
