WORLDTECHRecord-intensity attosecond X-ray pulses from European XFEL could aid electron studies
Researchers working at the European XFEL have produced X-ray flashes that are extremely short and reach a record intensity for pulses of this kind. The team reports that the method could support detailed studies of electrons in atoms and molecules.
Focusing light into a minute, powerful spot
According to the report, the researchers concentrated the X-ray light onto a spot so small that its area is roughly 100,000 times below the cross section of a typical human hair. The tight focus concentrates the light into a tiny but extremely powerful point.
The record intensity applies to this particular class of pulses, which the researchers produced at the European XFEL facility.
Possible uses for electron research
The technique could allow detailed examination of how electrons behave inside atoms and molecules. Over the longer term, the report suggests it might even let scientists steer electrons while chemical reactions are taking place.
The team has published the results of the experiment, which was carried out in April 2026, in the journal Optica.
Open questions
- How far could the approach be extended to control electrons during chemical reactions?
