The recently beamline ANATOMIX (Advanced Nanotomography and Imaging with Coherent X-Rays) at SOLEIL is dedicated to three-dimensional imaging with hard X-rays at microscopic length scales. It is one of two “long” beamlines at SOLEIL, which allows its users to benefit from a very coherent X-ray beam and thus obtain images of exceptionally good contrast and resolution.
The new nanotomography end station on ANATOMIX works in a photon energy range from 5 to 20 keV. Based on the concept of a full-field transmission X-ray microscope (TXM), it yields a spatial resolution in 3D on the order of 100 nm and below. In complement to X-ray microtomography, which gives access to length scales down to around 500 nm, users at ANATOMIX can now explore complex biological structures or materials systems in three dimensions with a resolution down to 20 nm (pixel size).
The Arabidopsis thaliana seeds studied by the INRA team have a diameter around 0.3 mm and have been measured without cutting the specimen. The data acquisition time for a full tomographic volume was 2.5 minutes. Figure b shows virtual cuts extracted from 3D volume images obtained with tomography at different length scales up to the entire grain.
Within four days of the experiment, more than 200 nanotomography, as well as high-resolution microtomography volume scans, have been acquired by the user team. For ANATOMIX, it was also the first time that both techniques have been combined in a single experiment.
This first team of external users will soon be followed by several more. If you are interested in submitting a proposal for the next call for proposals, contact the beamline scientists!
SOLEIL is the French synchrotron, both a large scale facility and a research laboratory.
The high-technology facility, SOLEIL is providing both an electromagnetic radiation source covering a wide range of energies and a research laboratory at the cutting edge of experimental techniques dedicated to matter analysis down to the atomic scale, as well as a service platform open to all scientific and industrial communities.
