Simbol-X is arguably the most powerful broad-band focusing hard (0.5-80 keV) X-ray telescope operating in the 2013 timeframe. The combination of good angular resolution, broad energy response, and efficient observing provided by a good field of view and high orbit will provide a very large increase in sensitivity in a hitherto relatively unexplored spectral region. This will enable key scientific investigations including a census of supermassive black holes in the crucial energy range in which the cosmic X-ray background peaks, measurements of the geometry and dynamics of accretion in black hole binaries, characterization of hard X-ray sources in the Galactic center, and the nature and origin of energetic particles in galaxy clusters and supernova remnants. Its single optics module contains a set of nested nickel shells coated with multilayers to boost the high-energy response and the field of view. Its focal plane detectors are a novel hybrid configuration, with thick-depletion silicon providing the low energy response, and Cadmium Telluride the high energy response. To achieve the long focal length necessary for large collecting areas at high energies, the optics and detectors are on separate high-earth-orbit formation-flying spacecrafts, 20 m apart.
We describe a proposed US participation in the Simbol-X program to provide technical expertise in the area of multilayer coatings for the X-ray optics; expertise in science and the X-ray testing and calibration of the flight optics; and support as a data analysis, Guest Investigator, and archiving center. The use of the NASA DSN Goldstone station, as a complement to the Malindi tracking station,will also be provided.
