Velocity bunching at the European XFEL [PDF]

2007 IEEE Particle Accelerator Conference (PAC), 2007
This paper explores the possibility to employ velocity bunching [1] in the first RF module of the European XFEL [2] (referred to as XFEL in this paper) to increase the peak current at the injector exit. The current increase will reduce the total longitudinal bunch compression factor and loosen rf jitter tolerances by the same amount.

Stability of Bragg reflectors under megahertz heat load at XFELs

Journal of Synchrotron Radiation, 2023
Modern X-ray free-electron laser (XFEL) sources can deliver photon pulses with millijoule pulse energies and megahertz repetition rate. As shown by the simulations in this work, for particular cases the dynamical heat load effects for Bragg reflectors ...

Megahertz data collection from protein microcrystals at an X-ray free-electron laser

Nature Communications, 2018
The European X-ray free-electron laser (EuXFEL) in Hamburg is the first megahertz (MHz) repetition rate XFEL. Here the authors use lysozyme crystals and microcrystals from jack bean proteins and demonstrate that damage-free high quality data can be ...

XFELs for structure and dynamics in biology [PDF]

IUCrJ, 2017
The development and application of the free-electron X-ray laser (XFEL) to structure and dynamics in biology since its inception in 2009 are reviewed. The research opportunities which result from the ability to outrun most radiation-damage effects are outlined, and some grand challenges are suggested.
