Abstract

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.
