microXAS - X05LA: Environmental & Materials Sciences
Two additional features make the microXAS beamline a rather exceptional and exclusive X-ray microprobe facility. First, the microXAS beamline permits the investigation of radioactive materials and corresponds to the world-wide solely microprobe facility being able to analyze radioactive sample with 1µm spatial resolution. Second and definitely going beyond any existing X-ray microprobe instrumentation, the FEMTO project is an integral part of the microXAS beamline project. Ultrafast time-resolved X-ray studies with a resolution of picoseconds down to ~100 femtoseconds are ‘routinely’ carried out at the microXAS beam line.
|Energy range||~3 - 23 keV|

The reaction of elemental scandium and zirconium powders with liquid aluminum is observed directly via operando X-ray diffraction during laser 3D printing. This work demonstrates that elemental blends can be used to create fine-grained crack-free Al-alloys and highlights the importance of feature size.
A new simulation of the most dangerous radioactive debris from the Fukushima nuclear power plant will help with clean-up efforts.
