Thermoelastic effects in Bragg reflectors as a potential bottleneck for XFELs with megahertz repetition rate

Communications Physics
While MHz repetition rates at modern X-ray free-electron laser (XFEL) facilities achieve remarkable capabilities for imaging, the high repetition rates may also lead to new stability problems.

Harnessing the power of an X-ray laser for serial crystallography of membrane proteins crystallized in lipidic cubic phase

IUCrJ, 2020
Serial femtosecond crystallography (SFX) with X-ray free-electron lasers (XFELs) has proven highly successful for structure determination of challenging membrane proteins crystallized in lipidic cubic phase; however, like most techniques, it has ...

Principles and applications of x-ray light sources driven by laser wakefield acceleration

Physics of Plasmas, 2023
One of the most prominent applications of modern particle accelerators is the generation of radiation. In a synchrotron or an x-ray free electron laser (XFEL), high energy electrons oscillating in periodic magnetic structures emit bright x rays. In spite

XANES and EXAFS of dilute solutions of transition metals at XFELs.

Journal of Synchrotron Radiation, 2019
This work has demonstrated that X-ray absorption spectroscopy (XAS), both Mn XANES and EXAFS, of solutions with millimolar concentrations of metal is possible using the femtosecond X-ray pulses from XFELs.
