Macromolecular Crystallography (MX) is an essential technique to determine the structure of biological molecules like proteins and nucleic acids to high resolution. 4th generation sources such as MAX IV, coupled with the use of advanced beamline instrumentation and fast readout detectors make it possible to study macromolecular crystals both by the conventional rotation method and
The multimodal in-situ XAS-XRD endstation is used for in-situ / in-operando investigations with a total time resolution of currently about 20s. Exemplary data is shown here: In-situ data from the formation of metal halide perovskite thin-films (in-FORM project)
FragMAX is a user facility for crystallographic fragment screening at the BioMAX beamline at MAX IV Laboratory. The facility is accessible to Swedish and international scientists from academia and industry. It provides simple workflows for large-scale crystal preparation, data collection and analysis. Users with different levels of experience are enabled to routinely find starting points
More information on beamline optics and experimental stations pages. NEW! Long Term Proposals (LTP) SPECIES accepts LTPs in the Fall26 call. More information about LTPs is available here! APXPS proposal submission. As there are two complimentary APXPS beamlines at MAX IV, many proposals could be carried out at either HIPPIE or SPECIES. Such proposals can therefore be submitted with a preference
The RIXS (Resonant Inelastic X-ray Scattering) technique was pioneered already in the 1980’s, and since then it has provided a broad range of applications. It relies heavily on access to a high brilliance source of primary photons, and it is only recently that the full power of the method has been realised. The new synchrotrons
SPECIES is an undulator based soft X-ray beamline, located at the 1.5 GeV storage ring. The offered experimental techniques are Ambient Pressure X-ray Photoelectron Spectroscopy (APXPS), X-ray Absorption Spectroscopy (XAS), X-ray Emission Spectroscopy (XES) and Resonant Inelastic X-ray Scattering (RIXS). The beamline has two branches that use a common elliptically polarizing undulator (EPU61) and a
SoftiMAX is a soft X-ray beamline, dedicated to spectromicroscopy and coherent imaging. The beamline operates in the photon energy range between 275 eV and 2.5 keV and has two branch lines: one for STXM and Ptychography with a sub-100 nm focus, and one modular line for coherent and full-field techniques that require a larger beam
The hard X-ray nanoprobe of Max IV – NanoMAX – is designed to take full advantage of MAX IV’s exceptionally low emittance and the resulting coherence properties of the X-ray beam. The beamline is a powerful X-ray microscope. It focuses the coherent X-ray beam to an a tiny (below 100 nm) and extremely intense and
MicroMAX is opening up new possibilities in the area of structural biology making it possible to study proteins in 3D and to follow them in time. MicroMAX will allow studying the molecules that are most interesting but most difficult to study because they only provide microcrystals. MicroMAX provides a very small but parallel and intense
Research in a wide range of disciplines – magnetism, materials science, nano-science, heterogeneous catalysis, corrosion science, polymer science, to name but a few – is in strong need of improved surface imaging techniques with structural, chemical, electronic, and magnetic contrasts at spatial resolutions in the nanometer range.
