The HTRS is the only instrument matching the top level mission requirement of handling a one Crab X-ray source with an efficiency greater than 10%. It will provide IXO with the capability of observing the brightest X-ray sources of the sky, with sub-millisecond time resolution, low deadtime, low pile-up (less than 2% at 1 Crab), and CCD type energy resolution (goal of 150 eV FWHM at 6 keV). The HTRS is a non-imaging instrument, based on a monolithic array of Silicon Drift Detectors (SDDs) with 31 cells in a circular envelope and a X-ray sensitive volume of 4.5 cm2 x 450 µm. As part of the assessment study carried out by ESA on IXO, the HTRS was studied by a consortium led by CNES and CESR. In this paper, we will describe the expected per- formance of the HTRS, as assessed through Monte Carlo simulations. We will illustrate the instrument capabilities. 13 2 Multiwavelength high-time resolution observa- tions Piergiorgio Casella School of Physics & Astronomy, University of Southampton, UK The study of X-ray variability in X-ray binaries has represented - and still is - one of the most powerful tools to study the accretion flow in the vicin- ity of compact objects. The advent of new instrumentation during the last decade has made possible to extend high time resolution astronomy to op- tical and infrared wavelengths. This has opened new exciting windows, as the novel technique of echo-tomography, which allows us to map the binary geometry, and the study of the fast-variable emission from relativistic jets, which provides unprecedented insights on the geometry and the Physics of the jets themselves.
