Samenvatting
Europe is one of the major partners building the International Space
Station (ISS) and European industry, together with ESA, is responsible
for many station components including the Columbus Orbital Facility, the
Automated Transport Vehicle, two connecting modules and the European
Robotic Arm. Together with this impressive list of contributions there
is a strong desire within the ESA Member States to benefit from this
investment by utilizing the unique capabilities of the ISS to perform
world-class science. XEUS is one of the astronomical applications being
studied by ESA to utilize the capabilities of the ISS. XEUS will be a
long-term X-ray observatory with an initial mirror area of 6 m
2 at 1 keV that will be expanded to 30 m 2
following a visit to the ISS. The 1 keV spatial resolution is expected
to be 2-5″ half-energy-width. XEUS will consist of separate
detector and mirror spacecraft (MSC) aligned by active control to
provide a focal length of 50 m. A new detector spacecraft, complete with
the next generation of instruments, will also be added after visiting
the ISS. The limiting 0.1-2.5 keV sensitivity will then be 4 × 10
-18 erg cm -2 s -1, around 200 times
better than XMM-Newton, allowing XEUS to study the properties of the hot
baryons and dark matter at high redshift.
