What are X-Ray Free-Electron Lasers? X-ray free-electron lasers (XFELs) are a revolutionary type of X-ray source that produce ultra-short, highly intense pulses of X-rays. Unlike conventional X-ray ...

New research by scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with scientists from TAU Systems Inc., has brought the promise of ...

Free electron lasers (FELs) are paramount in a number of fields including atomic and molecular physics, material science as well as biology and medicine. The working principle of FEL is different from ...

Smith-Purcell radiation arises when a charged particle, typically an electron, travels in close proximity to a periodic grating, thereby inducing electromagnetic emission that is inherently tunable ...

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 ...

Representation of domain walls within a ferromagnetic layered material. New research shows that when these materials are hit with a free electron laser, magnetic domain walls move much faster than ...

The US Navy has contracted Boeing to work on a Free Electron Laser, which would provide ships with an ultra-precise weapon capable of striking targets with lethal force, causing minimal nearby damage.

At ASU's Biodesign Institute in building C, there's a 3D-printed model of a machine in the basement. Signs around the model say "fragile" and "do not touch." But Mark Holl picks up a piece of it ...
