NanoMAX is the first hard X‐ray nanoprobe beamline at the MAX IV laboratory. It utilizes the unique properties of the world's first operational multi‐bend achromat storage ring to provide an intense and coherent focused beam for experiments with several methods. In this paper we present the beamline optics design in detail, show the performance figures, and give an overview of the surrounding infrastructure and the operational diffraction endstation.

BioMAX is the first macromolecular crystallography beamline at the MAX IV Laboratory 3 GeV storage ring, which is the first operational multi‐bend achromat storage ring. Due to the low‐emittance storage ring, BioMAX has a parallel, high‐intensity X‐ray beam, even when focused down to 20 µm × 5 µm using the bendable focusing mirrors. The beam is tunable in the energy range 5–25 keV using the in‐vacuum undulator and the horizontally deflecting double‐crystal monochromator. BioMAX is equipped with an MD3 diffractometer, an ISARA high‐capacity sample changer and an EIGER 16M hybrid pixel detector. Data collection at BioMAX is controlled using the newly developed MXCuBE3 graphical user interface, and sample tracking is handled by ISPyB. The computing infrastructure includes data storage and processing both at MAX IV and the Lund University supercomputing center LUNARC. With state‐of‐the‐art instrumentation, a high degree of automation, a user‐friendly control system interface and remote operation, BioMAX provides an excellent facility for most macromolecular crystallography experiments. Serial crystallography using either a high‐viscosity extruder injector or the MD3 as a fixed‐target scanner is already implemented. The serial crystallography activities at MAX IV Laboratory will be further developed at the microfocus beamline MicroMAX, when it comes into operation in 2022. MicroMAX will have a 1 µm × 1 µm beam focus and a flux up to 1015 photons s−1 with main applications in serial crystallography, room‐temperature structure determinations and time‐resolved experiments.

With the introduction of the multi‐bend achromats in the new fourth‐generation storage rings the emittance has decreased by an order of magnitude resulting in increased brightness. However, the higher brightness comes with smaller beam sizes and narrower radiation cones. As a consequence, the requirements on mechanical stability regarding the beamline components increases. Here an innovative five‐axis parallel kinematic mirror unit for use with soft X‐ray beamlines using off‐axis grazing‐incidence optics is presented. Using simulations and measurements from the HIPPIE beamline at the MAX IV Laboratory it is shown that it has no Eigen frequencies below 90 Hz. Its positioning accuracy is better than 25 nm linearly and 17–35 µrad angularly depending on the mirror chamber dimensions. [ABSTRACT FROM AUTHOR]
