| WEPH36 | From Plate Screening to Artificial Intelligence: Innovative developments on PROXIMA 2A at Synchrotron SOLEIL | 283 |
|
||
| PROXIMA 2A is a high performance 3rd generation synchrotron beamline dedicated to X-ray micro-crystallography on biological macromolecules. Since opening in March 2013, the experimental station has hosted a large number of users who have collected vast amounts of X-ray diffraction images from literally thousands of crystals. In order to streamline the throughput, enhance performance and add functionality, a number of innovative developments have been launched on PROXIMA 2A. These cover all aspects of the beamline, from the practical to the visionary: such as the design, fabrication and implementation of a dedicated high-precision motorized stage to screen crystallization plates for in situ X-ray data collections, and the employment artificial intelligence and computer vision technologies for the detection of samples under liquid nitrogen. Other notable beamline projects include the addition of a vertical translation table for the EIGER X 9M detector to permit the acquisition of ultrahigh (0.6 Å) resolution X-ray data, the incorporation of a miniaturized YAG-coupled photodiode within a beamstop and the determination of the SOC of a recently added kappa arm to the goniometer. | ||

| THPH09 | Design of Indirect X-Ray Detectors for Tomography on the Anatomix Beamline | 355 |

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.

| THPH32 | Dual Beam Visualizer - Intensity Monitor for Lucia Beamline at SOLEIL Synchrotron | 403 |
|

|
LUCIA is a micro-focused beamline (0.8 - 8 keV) dedicated to X-ray fluorescence and X-ray absorption spectroscopy at SOLEIL Synchrotron.* With its recent optical upgrade and photons flux increase, the three pink-beam diagnostics of the beamline have been upgraded to support a beam reaching 1013ph/s and 20 W/mm². This paper presents the thermomechanical study and the realization of new devices adapted to the current constraints of use, making possible to both visualize the shape of the pink beam and to measure its intensity simultaneously in the same compact device. The beam is visualized by a piece of Al2O3 - Cr ceramic, soldered to a copper heat sink, whose fluorescence image is visible in visible light with a suitable camera and optical system. The measurement of the photonic intensity is made by a polarized CVD diamond used as a photosensitive element, the current reading is made by a suitable low current amplifier. The design of this dual beam visualizer and intensity monitor, made by the SOLEIL detectors group with thermomechanical studies done by the Mechanical Design Office, will be presented in details. In-lab measurements will be also presented.
