The fourth generation of synchrotron radiation sources, commonly referred to as the Free
Electron Laser (FEL), provides an intense source of brilliant X-ray beams enabling the …

In this article, the concept of a recently funded R&D project for the installation of a proof-of-
concept cavity-based x-ray free electron laser (CBXFEL) demonstrator experiment at the …

Undulator tapering controls the resonance properties of the free-electron laser (FEL)
amplification process. Wakefield energy losses in an undulator's vacuum chamber are one …

The parallel operation of multiple undulator lines with a wide spectral range is an important
way to increase the usability of x-ray free electron laser (XFEL) facilities, especially for …

We present measurements of slice energy spread at the injector section of the European X-
Ray Free Electron Laser for an electron bunch with charge of 250 pC. Two methods …

We consider a 3D electron bunch at the cathode, modelled via photoemission, with realistic
(asymmetric) spatial and temporal distributions for accelerator beam dynamics studies at the …

X-ray free-electron lasers based on superconducting accelerator technology deliver
ultrashort photon pulses with unprecedented peak brilliance at high repetition rates …

Sub-ångström working regime refers to a working state of free-electron lasers which allows
the generation of hard X-rays at a photon wavelength of 1 ångström and below, that is, a …

Electro-optical detection has proven to be a valuable technique to study temporal profiles of
THz pulses with pulse durations down to femtoseconds. As the Coulomb field around a …
