  During the ALBA design phase, the protein macromolecular protein crystallography beamline, XALOC, required several in-house developments. The major part of these designs was at the end station where the necessity of customization is always much higher. The most relevant of these instruments was the beam conditioning elements table [1]. This accurate stage, which supports the diffractometer as well, includes the four movements required to align the components to the nominal beam as well as position the diffractometer. This design compacts, especially the vertical and pitch movements, both in a single stage, with a couple of stages for all four excursions. The solution maximise the stiffness and preserves at the same time the resolution close to 0.1µm while being able to withstand a half tone of payload. Thanks this compactness and performances this design concept, the vertical and pitch combined stage, was not only applied at XALOC for its diffractometer and detector table, but it has been widely adapted at several ALBA beamlines: at NCD-SWEET [2] as a detector table, a beam conditioning elements table [3] and sample table, at MSPD beamline as the KB table, at NOTOS beamline as metrology table, and also at the new ESA MINERVA beamline [4] for their sample mirror modules positioning. Beamlines have not been the only beneficiaries of this design, also different kind of instrumentation like an hall probe measuring bench [5], and even a stitching platform for the ALBA optics laboratory [6]. Moreover, the concept has outreach ALBA and has been adopted also at other facilities worldwide, synchrotrons and also scientific instrumentation suppliers around Europe. This poster presents most of the applications of the skin concept and their variations and main measured performances.

ForMAX is a new beamline at the MAX IV Laboratory for multi-scale structural characterization of hierarchical materials from nm to mm length scales with high temporal resolution. This is achieved by combining full-field microtomography with small- and wide-angle X-ray scattering (SWAXS) in a novel manner. The principal components of the endstation consist of two units of beam conditioning elements, a sample table, an evacuated flight tube and a detector gantry. The beam conditioning units include a diamond vacuum window, an attenuator system, a fast shutter, a slit collimation system, two sets of compound refractive lenses, three X-ray beam intensity monitors, a beam viewer and a telescopic vacuum tube. The sample table has been optimized with respect to flexibility and load capacity, while retaining sub-micron resolution of motion and high stability performance. The nine metre long and one metre diameter evacuated flight tube contains a motorised detector trolley, enabling the sample-detector position for small-angle X-ray scattering (SAXS) to be easily adjusted under vacuum conditions. Finally, a two metre high and two metre wide granite gantry permits independent and easy movement of the tomography microscope and wide-angle X-ray (WAXS) detector in and out of the X-ray beam. To facilitate propagation-based phase-contrast imaging and mounting of bulky sample environments, the gantry is mounted on motorized floor rails. All these characteristics will allow to combine multiple complementary techniques sequentially in the same experiment with fast efficient switching between setups. The ForMAX endstation is presently in the design and construction phase, with commissioning expected to commence early 2022.
