DiffMAX/MatMAX: The hard x-ray eyes of material scientists at the atomic scale

Mankind currently faces a number of grand challenges to continue living on this planet in a sustainable way. The technological progress accomplished using the natural resources of earth, from the metal in the mines to the oil used for energy or the synthesis of many chemicals and pharmaceuticals, has allowed tremendous increase of the standard of living across the planet, but not without a high environmental cost which we now must adress.

The material sciences have taught us through centuries of learning, that understanding how the fundamental building blocks of matter, atoms and molecules, interact, allows us to predict how they will behave when used in larger objects and devices.

This knowledge is fundamental in our quest to a better usage of natural resources, developing lithium batteries and solar cells, reducing our carbon footprint, or designing better drugs, new ultra light materials, hyperalloys or bio-compatible implants.

DiffMAX is a beamline project aiming at meeting the needs of material research using the exceptionnal capabilities of the MAX IV source in the hard x-ray range (3-45 keV).

DiffMAX offers two experimental stations, one providing excellent capabilities for powder diffraction (PXRD), and one flexible station equipped for receiving large experimental environments and with a high accuracy detector positioning for grazing incidence diffraction and scattering techniques on solid and liquid surfaces and interfaces (SXRD, GIXD, GISAXS, Reflectivity). The second station will also allow other types of experimental setups to be mounted (high pressure cell or user electron analyzer for example). Both stations will allow operando studies.

Academic and industrial researchers have already expressed a strong support for the project. The philosophy of the beamline will be to provide a competent and fertile environment to foster and exploit innovative ideas and measurement techniques for all types of material sciences.

Two workshops are currently planned to gather inputs from the user community:

  • DiffMAX combined with electron spectroscopies-opportunities for materials’ research at MAX IV March 22/23, at Ångström Laboratory Uppsala, co-organized by MAX IV and Ångström Laboratory. Purpose of the meeting: We want to gather scientists interested in material science with X-rays using diffraction methods or spectroscopic methods (or both) to 1) see examples of XRD/PES combinations presented by invited speakers and 2) discuss how we can use the combination of techniques to do new science at the proposed DiffMAX beamline.

  • DiffMAX National workshop March 27/28 at Sankt Jörgen Park, Göteborg, co-organized by MAX IV and Chalmers.
    In this workshop, we wish to gather the different materials science communities, inform them of the possibilities offered by the MAX IV source, and provide a forum to influence the detailed beamline design so that it meets the demands of the communities in an optimum way.
    The aim of the workshop is to produce a document containing a list of scientific cases together with a conceptual and technical description of the beamline. This will be accomplished by working groups during the workshop.
