Resolving molecular diffusion and aggregation of antibody proteins with megahertz X-ray free-electron laser pulses [PDF]

Nature Communications, 2022
The European X-ray FreeElectron Laser Facility generates ultrashort hard X-ray pulses with megahertz repetition rate. Here, the authors probe the dynamics of dense antibody protein (Ig-PEG) solutions using megahertz X-ray photon correlation spectroscopy ...

Attosecond X-ray free electron laser [PDF]

EPJ Web of Conferences, 2013
For a real, meaningful pump-probe experiment with attosecond temporal resolution, an isolated attosecond pulse is in demand. In this vein we report the generation of an isolated ~ 148 attosecond pulse duration radiation pulse at 0.1 angstrom wavelength ...

Pair Creation and an X-ray Free Electron Laser [PDF]

Physical Review Letters, 2001
Using a quantum kinetic equation coupled to Maxwell's equation we study the possibility that focused beams at proposed X-ray free electron laser facilities can generate electric field strengths large enough to cause spontaneous electron-positron pair ...

X-ray optics for the cavity-based X-ray free-electron laser. [PDF]

J Synchrotron Radiat
A cavity-based X-ray free-electron laser (CBXFEL) is a possible future direction in the development of fully coherent X-ray sources. CBXFELs consist of a low-emittance electron source, a magnet system with several undulators and chicanes, and an X-ray cavity.

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 ...

Ultrashort Free-Electron Laser X-ray Pulses [PDF]

Applied Sciences, 2017
For the investigation of processes happening on the time scale of the motion of bound electrons, well-controlled X-ray pulses with durations in the few-femtosecond and even sub-femtosecond range are a necessary prerequisite.
