Briefings

Researchers at the European XFEL successfully generated attosecond hard-X-ray pulses with record intensity, focusing light into a spot 100,000 times smaller than a human hair. Published in April 2026 in Optica, this achievement enables detailed electron behavior studies and future control of electrons in chemical reactions.

Key points

• The European XFEL produced attosecond hard-X-ray pulses reaching record intensity.
• The focused spot size was approximately 100,000 times smaller than a human hair.

Context

This breakthrough utilizes the European XFEL facility to generate ultra-short X-ray flashes, enabling new capabilities in electron dynamics research.

Limitations

The evidence is limited to the experimental results published in April 2026. No further data on long-term feasibility or specific electron control mechanisms is provided.
