Synchrotron microtomography

Synchrotron microtomography (SR-µCT) is a non-destructive 3D imaging technique that allows the internal structure of materials and components to be visualised with micrometric resolution and higher contrast than laboratory microtomography.

Thanks to the intensity and coherence of synchrotron radiation, SR-µCT reveals details that would otherwise be invisible, with unrivalled speed and reliability.

Assests of synchrotron microtomography

  • Micrometre resolution, even on large samples

  • High contrast, even between weakly absorbing materials

  • Fast acquisition, suitable for dynamic monitoring or large series inspections

  • Wide range of sample sizes

  • Reduction of metal artefacts and beam hardening

  • Multi-scale tomography

Synchrotron microtomography measurements and analyses

  • Detection and quantification of porosity, inclusions and internal cracks
  • 3D mapping of microstructure: grains, fibres, phases
  • Inspection and characterisation of coatings and interfaces
  • In situ monitoring (4D): thermal and mechanical transformations in real time
  • Non-destructive material health analysis
  • 3D reconstruction of cracks
  • Weld inspection
  • CAD comparison

Some technical characteristics

Synchrotron sources make it easy to achieve advanced technical specifications for samples ranging in size from 0.5 mm to 2 m!

 

  • High resolution: pixel size from a few hundred nm to a few tens of µm.
  • High throughput: with acquisition times ranging from a few tens of seconds to a few minutes.
  • Varied contrasts: absorption, phase with possible reinforcement depending on the issue
  • Wide energy range: high beam intensity even at 300 keV
  • Real-time tomography possible: sample under thermal and mechanical stress, in a controlled environment, etc.
