The first dark field x-ray microscopy workshop

During the last 8 years a group of SOLID researchers have demonstrated a new x-ray method – Dark Field X-ray Microscopy  - and implemented this as an instrument at the European Synchrotron X-ray Facility, ESRF. 

Uniquely DFXM can visualize how domains and defects change deep inside hard crystalline materials during processing. May 6-7 a very successful DFXM workshop was held at ESRF with 80 participants, presenting the first scientific results emerging from the new microscope.

A second generation instrument is already being built at ESRF,  as one of four flagship projects related to the new x-ray source. Planned to be inaugurated in 2022, this will provide up to 1000 times more photons. Two DTU teams led by Hugh Simons and Henning Friis Poulsen will continue to spearhead these activities via two new ERC grants. 

Moreover, the imaging branch of the beamline DanMAX will also provide DFXM capabilities, when that is opened to users – also in 2022.

In March 2021, DTU's 3D Imaging Center, 3DIM, in Lyngby has assisted the Natural History Museum of Denmark in Copenhagen with 3D scanning of a 66 million-year-old Tyrannosaurus rex skull. The scan is part of a digitization project of the natural heritage.

DTU Compute and DTU Physics will develop new methods to (mass) digitize natural heritage animals and insects, so that museum objects are accessible to all, and at the same time digital copies are preserved.

At the end of December 2020 a first tomogram in a pure phase contrast mode has been taken at DanMAX. X-ray phase contrast imaging allows studying low-absorbing samples with high energy X-rays, which reduces dramatically the deposited radiation dose and eliminating beam damage of the sample. It is especially important for biological samples, where a micro-CT scan can irreversibly destroy its DNA.

A fragment (approx. 1 mm in height) of a Dermestes genus beetle was scanned in an propagation-based phase contrast mode (a), which is one of the main modes of DanMAX full-field imaging. X-ray phase has been retrieved using the Paganin method (b), and a 3D volume was reconstructed with a conventional filtered back projection algorithm (c and d are the horizontal and vertical slices through the reconstructed volume). Semi-transparent rendered volume (e) reveals both, external shape and internal organs of the insect.
