High-brightness electron injectors for high-duty cycle X-ray free electron lasers

Frontiers in Physics, 2023
The successful development in the last two decades of X-ray free electron lasers (FELs) with their revolutionary brightness performance has been tightly dependent on the parallel development of electron guns and injectors capable of providing the high ...

Laser assisted electron beam conditioning for free electron lasers

Physical Review Special Topics. Accelerators and Beams, 2005
A new method for electron beam conditioning in free electron lasers is proposed. It uses the electron beam interaction with a laser light in two wiggler magnets separated by a strong-focusing channel.

Photoelectron Diffraction Imaging of a Molecular Breakup Using an X-Ray Free-Electron Laser

Physical Review X, 2020
A central motivation for the development of x-ray free-electron lasers has been the prospect of time-resolved single-molecule imaging with atomic resolution.

Enhanced harmonic generation in x-ray free-electron lasers

Physical Review Special Topics. Accelerators and Beams, 2014
Harmonic generation becomes increasingly important as x-ray free-electron lasers push to shorter wavelengths. Recent studies have pointed to the possibility of enhancing harmonic generation by detuning the fundamental.

Laser-pumped coherent x-ray free-electron laser [PDF]

Physical Review Special Topics - Accelerators and Beams, 2009
In a laser-pumped x-ray free-electron laser (FEL) an intense laser field replaces the magnetic wiggler field of a conventional FEL. Depending on the intensity and quality of both the electron beam and pump laser, the Thomson backscattered radiation can be coherently amplified.

Multi-wavelength anomalous diffraction de novo phasing using a two-colour X-ray free-electron laser with wide tunability

Nature Communications, 2017
X-ray free-electron lasers produce bright femtosecond X-ray pulses. Here, the authors use a two-colour X-ray free-electron laser beam for simultaneous two-wavelength data collection and show that protein structures can be determined with multiple ...

Single-exposure X-ray phase imaging microscopy with a grating interferometer

Journal of Synchrotron Radiation, 2022
The advent of hard X-ray free-electron lasers enables nanoscopic X-ray imaging with sub-picosecond temporal resolution. X-ray grating interferometry offers a phase-sensitive full-field imaging technique where the phase retrieval can be carried out from a
