Ultrafast lasers tracked plasma formation and ionization in copper with picosecond precision. Results show rapid ion growth ...

Scientists at the Paul Scherrer Institute PSI have, for the first time, demonstrated a technique that synchronizes ultrashort X-ray pulses at the X-ray free-electron laser SwissFEL. This achievement ...

The Nature Index tracks primary research articles from 145 natural-science and health-science journals, chosen based on reputation by an independent group of researchers. The Nature Index provides ...

Researchers from the University of Liverpool, Japan, and Argentina have captured atomic-resolution images of an important ...

At SwissFEL, PSI researchers demonstrated a technique known as mode-locking, which allows fully coherent, ultrashort X-ray pulses to be produced. In the photo, several undulator modules are visible ...

“Watch your head; watch your feet,” Eric Fauve says as he enters a cryoplant sitting in a landscape of dry grass, eucalyptus trees, and oaks in Northern California. “We have rattlesnakes, deer, ...

Ice-cold electron beams could pave the way to reducing X-ray free-electron lasers (X-FELs) to a fraction of their current size. Ice-cold electron beams simulated in research at the University of ...

For the first time, researchers have demonstrated that a laser-plasma accelerator can reliably drive a free-electron laser ...

A new way of producing coherent light in the ultra-violet spectral region, which points the way to developing brilliant table-top x-ray sources. A new way of producing coherent light in the ...

An international team has used X-ray Free Electron Laser (XFEL) technology to capture atomic-resolution images of copper nitrite reductase, a key enzyme in the global nitrogen cycle. The study, ...

Scientists use a ghost laser beam to spot tiny flaws while keeping a free-electron laser stable for hours. For decades, ...
