The Department of Energy (DOE) has given the green light for construction to begin on a high-energy upgrade that will further boost the performance of the Linac Coherent Light Source (LCLS), the world ...

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 ...

In a step toward making ultrabright X-ray sources more widely available, an international collaboration led by the University of Michigan—with experiments at the U.K.'s Central Laser Facility—has ...

Proof-of-concept experimental setup used to generate an extreme ultraviolet (XUV) free-electron laser (FEL) driven by a laser wakefield acceleration (LWFA) electron beam. An intense laser pulse, ...

For free-electron lasers like the European XFEL to deliver extremely short and reproducible X-ray laser pulses, the electron bunches that generate these pulses must be of outstanding quality and ...

LCLS-II-HE is the second upgrade in as many years for a laser beam in Menlo Park, California, that reveals some of nature's most microscopic mysteries in sharp detail. Reading time 3 minutes A new ...

Using intense X-rays, researchers captured a buckyball as it expanded, split and shed electrons under strong laser fields. Detailed scattering measurements showed how the molecule behaves at low, ...

Researchers at Stockholm University have used ultra-short X-ray laser pulses at facilities in South Korea to identify a long-hypothesized critical point in supercooled water, where two distinct liquid ...

Attosecond science, honored with the 2023 Nobel Prize in Physics, is transforming our understanding of how electrons move in atoms, molecules, and solids. An attosecond – equivalent to a billionth of ...
