Astro-E2 is the
X-ray satellite devoted to observations of celestial X-ray
It carries five soft
telescopes and one hard X-ray telescope. It is designed for "broad-band,
spectroscopy, ranging from soft X-rays up to gamma-rays (0.3 -
600 keV). Astro-E2
planned to be lauched in early 2005 from the Kagoshima Space Center
Japan. The Astro-E2
is managed by ISAS, collaborating with many Japanese universities
and US institutes.
Astro-E2 XRT at the PANTER Test
In August 2003 the calibration of the
Astro-E2 flight mirror is performed at the PANTER test facility.
Two weeks of calibration will

~50 kg is hooked on a crane to be moved into the vacuum chamber. This
maneuver is necessary because the mirror has to be moved over the
integrated detectors of the PANTER facility: A Position Sensitive
Pounter (the flight spare model of the ROSAT PSPC) and a pn-CCD camera
(the flight spare model of the XMM-Newton EPIC-pn camera)
