X-ray free-electron lasers [PDF]

Journal of Physics B: Atomic, Molecular and Optical Physics, 2005
In a free-electron laser (FEL) the lasing medium is a high-energy beam of electrons flying with relativistic speed through a periodic magnetic field. The interaction between the synchrotron radiation that is produced and the electrons in the beam induces a periodic bunching of the electrons, greatly increasing the intensity of radiation produced at a ...

An ultra-compact x-ray free-electron laser [PDF]

New Journal of Physics, 2020
Abstract In the field of beam physics, two frontier topics have taken center stage due to their potential to enable new approaches to discovery in a wide swath of science. These areas are: advanced, high gradient acceleration techniques, and x-ray free electron lasers (XFELs).

X-ray Free-Electron Laser [PDF]

Applied Sciences, 2018
During the last decades, the advent of the short-wavelength Free Electron Lasers (FELs) in the range from extreme ultraviolet (XUV) to hard X-rays has opened a new research avenue for the investigations of ultrafast electronic and structural dynamics in any form of matter[...]

Quantum Effects with an X-Ray Free-Electron Laser [PDF]

Physical Review Letters, 2002
A quantum kinetic equation coupled with Maxwell's equation is used to estimate the laser power required at an XFEL facility to expose intrinsically quantum effects in the process of QED vacuum decay via spontaneous pair production. A 9 TW-peak XFEL laser with photon energy 8.3 keV could be sufficient to initiate particle accumulation and the consequent

Vacuum birefringence at x-ray free-electron lasers

New Journal of Physics, 2021
We study the perspectives of measuring the phenomenon of vacuum birefringence predicted by quantum electrodynamics using an x-ray free-electron laser (XFEL) alone.

Attosecond-Angstrom free-electron-laser towards the cold beam limit

Nature Communications, 2023
Free-electron lasers (FELs) can produce bright X-ray pulses, but require high quality electron beams. Here the authors show how to generate and preserve ultrabright electron beams from plasma-based accelerators for ultra-compact, high-brightness X-ray ...

Transient nuclear inversion by x-ray free electron laser in a tapered x-ray waveguide

Physical Review Research, 2022
The enhancement of x-ray-matter interaction by guiding and focusing radiation from x-ray free electron lasers is investigated theoretically. We show that elliptical waveguides using a cladding material with a high atomic number, such as platinum, can ...
