Wide
field monitor in the X/hard-X range
to localize transients
-
Fast (<1 min)
autonomous
follow-up observations with
X-ray telescope (2000 cm2)
with
-
High resolution X-ray spectroscopy (0.1-10
keV range,
2eV resolution below 2 keV with TES microcalorimeters)
-
Wider field
(30-60’) for imaging with
5-10” resolution (CCD) for extended faint
structures and cluster survey
-
Low background: 600 km equatorial orbit (as
BeppoSAX)
Trade-off study driven by scientific requirements
is being carried out
