The HEASARC welcomes your participation in a brief survey to capture how users access and utilize HEASARC data, software, and services. The outcome(s) of this survey will be used to guide, prioritize, and plan our activities and development in the coming years. It contains 18 questions, generally takes just a few minutes to complete, and your answers will remain totally anonymous. We thank you in advance for your valuable feedback.
ASTRO-E was to be the Japan's fifth X-ray astronomy
mission, but was unfortunately lost during launch (10 Feb 2000).
Astro-E was developed at the Japanese
Institute of Space and Astronautical Science (ISAS) in collaboration
with the US and Japanese institutions.
Astro-E was to carry, among other instruments, a new type
of X-ray spectrometer, the X-ray micro-calorimenter, which provides an
unprecendent energy resolution compared to non-dispersive instruments.
early 2000 - (XRS has a 2 year lifetime) Energy Range : 0.4-700 keV Special Features
: First X-ray micro-calorimeter in space
Five nested conical thin-foil grazing incidence telescopes (XRT),
with a spacial resolution of < 1.5´. Four telescopes
are gold-coated (XRT-I) and one is platinum-coated (XRT-S).
At the focus of each telescope there is one of the following detectors :
X-ray Spectrometer (XRS; 0.4-10 keV; one unit)
It is X-ray micro-calorimeter composite of 32 pixels
at the foci of the XRT-S.
Energy resolution ~12 eV at 6 keV.
FOV 2´ X 4´
X-ray Imaging Spectrometer (XIS; 0.4-10 keV; four units)
Each units is a 1024 X 1024 pixel CCD detector
at the foci of one XRT-I.
FOV 19´ X 19´, eff. area per each 300 cm2 @
1 keV, energy resolution 130 eV (E/6keV)1/2
