	Funding: Knut and Alice Wallenberg Foundation ForMAX is an advanced beamline at MAX IV Laboratory, enabling multi-scale structural characterisation of hierarchical materials from nm to mm length scales with high temporal resolution. It combines full-field microtomography with small- and wide-angle x-ray scattering (SWAXS) techniques, operating at 8-25 keV and providing a variable beam size. The beamline supports SWAXS, scanning SWAXS imaging, absorption contrast tomography, propagation-based phase contrast tomography, and fast tomography. The experimental station is a versatile in-house design, tailored for various sample environments, allowing seamless integration of multiple techniques in the same experiment. The end station features a nine-meter-long evacuated flight tube with a motorized small-angle x-ray scattering (SAXS) detector trolley. Additionally, a granite gantry enables independent movement of the tomography microscope and custom-designed wide-angle x-ray (WAXS) detector. These features facilitate efficient switching and sequential combination of techniques. With commissioning completed in 2022, ForMAX End Station has demonstrated excellent performance and reliability in numerous high-quality experiments.

THOBM01	Structural Dynamic Testing and Design Evaluation of the Formax Detector Gantry
	G. Felcsuti, J.B. González Fernández MAX IV Laboratory, Lund University, Lund, Sweden
	ForMAX, a new beamline at MAX IV, offers multi-scale structural characterization of hierarchical materials from nm to mm length scales by combining full-field microtomography and small- and wide-angle x-ray scattering (SWAXS) techniques. The sample position features a two-meter-high granite gantry that enables independent movement of the tomography microscope and wide-angle x-ray (WAXS) detector in and out of the x-ray beam, as well as along the beam on motorized floor rails. Ensuring optimal experimental performance requires high stiffness and low vibration amplitudes which are challenging goals to achieve with such slender structures. This study focuses on the structural dynamics of the gantry and summarizes the verifications tests that were conducted to assess the structure¿s sensitivity to ambient disturbances. Experimental modal analysis was employed to investigate the structural dynamics of the gantry and the obtained mode shapes are compared to the finite element calculations based on the Modal Assurance Criterion (MAC). Special attention is paid to the pneumatic brake on the detector’s floor rails that was implemented to increase the lowest eigenfrequency of the gantry.
