Is radiation damage the limiting factor in high-resolution single particle imaging with X-ray free-electron lasers? [PDF]

Structural Dynamics, 2019
The prospect of single particle imaging with atomic resolution is one of the scientific drivers for the development of X-ray free-electron lasers. The assumption since the beginning has been that damage to the sample caused by intense X-ray pulses is one

Simultaneous operation of two soft x-ray free-electron lasers driven by one linear accelerator

New Journal of Physics, 2016
Extreme-ultraviolet to x-ray free-electron lasers (FELs) in operation for scientific applications are up to now single-user facilities. While most FELs generate around 100 photon pulses per second, FLASH at DESY can deliver almost two orders of magnitude

X-ray free-electron lasers [PDF]

Journal of Physics B: Atomic, Molecular and Optical Physics, 2005
In a free-electron laser (FEL) the lasing medium is a high-energy beam of electrons flying with relativistic speed through a periodic magnetic field. The interaction between the synchrotron radiation that is produced and the electrons in the beam induces a periodic bunching of the electrons, greatly increasing the intensity of radiation produced at a ...
