Estimated Performance of Nanoscopium at an Upgraded Synchrotron Soleil.

At the dawn of third generation synchrotron source upgrades the question of analytical performance of existing scanning X-ray nanoprobes at an upgraded source is of significant importance; what is the cost/performance/time-line figure-of-merit that they fully profit from the increased source brilliance? Synchrotron Soleil (France) considers the source upgrade to achieve near-diffraction limited performance up to the hard X-ray range. The present Soleil source is partially coherent; the vertical and horizontal beam properties are very different, the horizontal source size and divergence is much larger than the diffraction limit. The Nanoscopium hard X-ray nanoprobe beamline is dedicated to hierarchical length-scale fast scanning multi-technique imaging It has been designed for performing flux-versusresolution trade-off by selecting one or multiple coherence modes by its secondary source (SS) aperture. This also permits to filter out beamline-optics-caused instabilities. By combining both diffractive and reflective optics, both "fluxand coherence-hungry" applications could be implemented successfully in the 5-20 keV energy range. The spatial resolution [30 nm, 300 nm] and the scanned field-of-view can be easily adapted to the needs of the analytical techniques and scientific applications. The beamline offers simultaneous information on sample morphology by exploiting scanning X-ray microscopy techniques, coherent imaging and recently fast full field tomography [K.
