Vacuum birefringence at x-ray free-electron lasers [PDF]

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.

Single-shot X-ray absorption spectroscopy at X-ray free electron lasers [PDF]

Scientific Reports, 2023
X-ray Absorption Spectroscopy (XAS) is a widely used X-ray diagnostic method for studying electronic and structural properties of matter. At first glance, the relatively narrow bandwidth and the highly fluctuating spectral structure of X-ray Free ...

Structural enzymology using X-ray free electron lasers

Structural Dynamics, 2017
Mix-and-inject serial crystallography (MISC) is a technique designed to image enzyme catalyzed reactions in which small protein crystals are mixed with a substrate just prior to being probed by an X-ray pulse. This approach offers several advantages over

Sample delivery for serial crystallography at free-electron lasers and synchrotrons. [PDF]

Acta Crystallogr D Struct Biol, 2019
Current developments and challenges for serial sample delivery at synchrotrons and X-ray free-electron lasers are reviewed, including the new megahertz repetition-rate machines, with an emphasis on liquid injection and high-viscosity extrusion.

Pulse Duration of Seeded Free-Electron Lasers

Physical Review X, 2017
The pulse duration, and, more generally, the temporal intensity profile of free-electron laser (FEL) pulses, is of utmost importance for exploring the new perspectives offered by FELs; it is a nontrivial experimental parameter that needs to be ...

Free Electron Lasers [PDF]

Annual Review of Nuclear and Particle Science, 1985
The free electron laser (FEL) uses a high quality relativistic beam of electrons passing through a periodic magnetic field to amplify a copropagating optical wave (1-4). In an oscillator configuration, the light is stored between the mirrors of an open optical resonator as shown in Figure 1.

Free Electron Lasers

, 2015
Synchrotron radiation is emitted when electromagnetic fields exert a force on a charged particle. This opens the possibility to apply external fields with specific properties for the stimulation of electrons to emit more radiation.
