Description
The latest, 4th generation synchrotrons, offer nanometer-scale imaging resolution and fast data acquisition. However, corresponding existing sample manipulators mostly rely on quasistatic actuation principles and are built by stacking straightforward 1 DoF stages. This approach limits dynamics performance and precision. To address this challenge, MI-Partners developed on behalf of and in close collaboration with SOLEIL, a fully actively controlled 6-DoF sample manipulator based on electromagnetic actuation. This system enables fast scanning with nanometer precision, providing translational motions and continuous rotation, for full 360-degree angular tomography reconstructions. The demonstrator was realized as part of the LEAPS-INNOV project. This paper outlines the mechatronic design and development process to achieve first-time-right performance in high-end mechatronic systems. Finally, acceptance test results are presented, demonstrating nanometer-range tracking errors during high-speed 2D scanning modes (step-scan and fly-scan). The manipulator also revealed clear limitations in some commercially available fiber-based displacement interferometer systems.
