Suzaku
X-Ray Telescopes
The telescopes for Suzaku, also formerly known as Astro-E2, are the same
as for the original Astro-E: they consist of
4 thin-foil mirror systems, to be used on 4 seperate charge-coupled devices (CCD), and
one system with a slightly shorter focal length, to be used on the high resolution
spectrometer. The latter, unfortunately, was not used in the mission due to a failure of
the spectrometer cooling system. The telescopes utilize grazing incidence foil
optics in conical
approximation to focus X-rays. The design of the telescopes is the same as
for Astro-E and is similar to that of the ASCA (Advanced Satellite for Cosmology and
Astrophysics) telescopes.
