Creation of the European Network « Mediators connecting Industry to X-rays and Neutrons »

EARIV – European Analytical Research Infrastructure Village


On 22nd September 2020 the project reached a significant milestone: On the signing of a Letter of Intent the European network ‘Mediators connecting Industry to X-rays and Neutrons’ came officially into being. The network aims to support its members in several ways:

1. Speak with one voice towards facilities and political stakeholders in order to increase visibility and awareness of value creation by mediators
2. Reach new customers and collaborate on improved customer service by activating the complementary competences in the network
3. Advocate for easier non-academic access and use of facilities

Who can become a member? All entities providing commercial analytical services and interacting with synchrotrons or neutron facilities.

Among the founding members are the following institutions:

Anna Stenstam, CR Competence AB
Nikolaj Zangenberg, Grethe Vestergaard Jensen, Danish Technological Institute – DMRI
Fabia Gozzo, Excelsus Structural Solutions (Swiss) AG
Simon Jacques, FINDEN LTD
Barbara Fayard, NOVITOM
Tomas Lundqvist, RISE Research Institutes of Sweden
Derek Logan, SARomics Biostructures AB
Sophie Bouat, Science-SAVED (France)
Mårten Edwards, Robert Moberg, Uppsala Synchrotronix AB
Bernhard Hesse, XPLORAYTION GmbH

2nd Head of Business Development at ESRF (The European Synchrotron)

Very pleased to be hosting the « CAROTS » (www.carots.eu) network today at ESRF – The European Synchrotron and ILL – Institut Laue Langevin. The project is building a network of intermediaires, like NOVITOM, XPLORAYTION GmbH and SARomics Biostructures AB which help bridge between our amazing Large-Scale European Research Infrastructures and industry, supporting industrial R&D using the exceptional properties of these infrastructures.

X-ray microtomography

X-ray microtomography, like tomography and x-ray computed tomography, uses x-rays to create cross-sections of a physical object that can be used to recreate a virtual model (3D model) without destroying the original object. The prefix micro- (symbol: µ) is used to indicate that the pixel sizes of the cross-sections are in the micrometre range. These pixel sizes have also resulted in the terms high-resolution x-ray tomographymicro–computed tomography (micro-CT or µCT), and similar terms. Sometimes the terms high-resolution CT (HRCT) and micro-CT are differentiated, but in other cases the term high-resolution micro-CT is used. Virtually all tomography today is computed tomography.

X-ray microtomography

Micro-CT has applications both in medical imaging and in industrial computed tomography. In general, there are two types of scanner setups. In one setup, the X-ray source and detector are typically stationary during the scan while the sample/animal rotates. The second setup, much more like a clinical CT scanner, is gantry based where the animal/specimen is stationary in space while the X-ray tube and detector rotate around. These scanners are typically used for small animals (in vivo scanners), biomedical samples, foods, microfossils, and other studies for which minute detail is desired.

The first X-ray microtomography system was conceived and built by Jim Elliott in the early 1980s. The first published X-ray microtomographic images were reconstructed slices of a small tropical snail, with pixel size about 50 micrometers.

WAS – X-ray absorption spectroscopy

X-ray absorption spectroscopy (XAS) is a widely used technique for determining the local geometric and/or electronic structure of matter. The experiment is usually performed at synchrotron radiation facilities, which provide intense and tunable X-ray beams. Samples can be in the gas-phase, solution, or as solids.

XAS data is obtained by tuning the photon energy, using a crystalline monochromator, to a range where core electrons can be excited (0.1–100 keV, 16–16,022 aJ). The edges are, in part, named by which core electron is excited: the principal quantum numbers n = 1, 2, and 3, correspond to the K-, L-, and M-edges, respectively. For instance, excitation of a 1s electron occurs at the K-edge, while excitation of a 2s or 2p electron occurs at an L-edge.

X-ray absorption spectroscopy

XAS is a type of absorption spectroscopy from a core initial state with a well defined symmetry therefore the quantum mechanical selection rules select the symmetry of the final states in the continuum which usually are mixture of multiple components. The most intense features are due to electric-dipole allowed transitions (i.e. Δℓ = ± 1) to unoccupied final states. For example, the most intense features of a K-edge are due to core transitions from 1s → p-like final states, while the most intense features of the L3-edge are due to 2p → d-like final states.

XAS methodology can be broadly divided into four experimental categories that can give complementary results to each other: metal K-edge, metal L-edge, ligand K-edge, and EXAFS.
