29 July 2010Focal plane instrumentation for the Wide-Field X-ray Telescope
The three X-ray imaging focal planes of the Wide-Field X-ray Telescope (WFXT) Mission will each have a field of
view up to 1 degree square, pixel pitch smaller than 1 arcsec, excellent X-ray detection efficiency and spectral resolving
power near the theoretical limit for silicon over the 0.2 - 6 keV spectral band. We describe the baseline concept for the
WFXT focal planes. The detectors are derived from MIT Lincoln Laboratory CCDs currently operating in orbit on
Chandra and Suzaku. Here we describe the baseline WFXT focal plane instrumentation and briefly consider options for
alternative detector technologies.
