Design of Indirect X-Ray Detectors for Tomography on the Anatomix Beamline

ANATOMIX* is a long beamline for full-field tomography techniques at the French synchrotron SOLEIL [1]. It will operate in the energy range from 5 to 30 keV, and feature several operation modes via versatile optics configurations, including direct white beam propagation. Two methodologically different experimental stations will be used: parallel-beam X-ray shadowgraphy, for spatial resolution down to the sub-micron range, and full-field transmission X-ray microscopy down to a spatial resolution of less than 100 nm. To cover this large panel of experimental possibilities, the Detector Group, the Mechanical Engineering Group and beamline team have designed four dedicated indirect X-ray detector. For pixels in the sub-micron size range : a micro-tomography revolver camera for versatility, a high-efficiency camera for flux-limited experiments, and a high-resolution camera for the largest optical magnifications will be available. For experiments with a large X-ray beam and pixel sizes from several microns upward, a "large-field" camera completes the set. We describe these different assemblies with the detailed components and expected specification of each solution.
