The long undulator beamline ANATOMIX is devoted to full-field tomography investigations. This beamline offers absorption and phase-contrast 3D X-ray imaging with high spatial resolution and sensitivity, for applications in materials science, biology and biomedical research. It is a cutting-edge tool for the acquisition of volume data allowing morphometric analysis of complex, heterogeneous three-dimensional objects with volumes up to several cm3, and 3D spatial resolution from several microns down to less than 100 nanometers. The beamline operates in an X-ray photon energy range from 5 to 50 keV and above, ideal for imaging soft tissue and light materials.

The beamline currently offers two spectral modes:

  • filtered white beam;
  • monochromatic beam from a double-crystal monochromator (DCM, ΔE/E ≈ 10-4, up to ≈ 25 keV).

In addition, a double-multilayer monochromator (ΔE/E ≈ 10-2) will be put into operation soon (expected to be operational in 2020).

Two types experimental stations cover different ranges of spatial resolution:

  • Parallel-beam microtomography in absorption and phase contrast – spatial resolution down to 1 µm (smallest pixel size 300 nm; maximum possible beam size: 40 mm x 15 mm [H x V]).
  • Full-field transmission X-ray microscope (TXM, nanotomography) – spatial resolution down to 100 nm (pixel size from 20 to 80 nm; field of view 40 µm x 40 µm; discrete working energy values);

ANATOMIX is an Equipment of Excellence (EQUIPEX) funded by the Investments for the Future program of the French National Research Agency (ANR), project NanoimagesX, grant no. ANR-11-EQPX-0031.
