Structural enzymology using X-ray free electron lasers [PDF]

Structural Dynamics, 2017
Mix-and-inject serial crystallography (MISC) is a technique designed to image enzyme catalyzed reactions in which small protein crystals are mixed with a substrate just prior to being probed by an X-ray pulse. This approach offers several advantages over

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

Attosecond-Angstrom free-electron-laser towards the cold beam limit

Nature Communications, 2023
Free-electron lasers (FELs) can produce bright X-ray pulses, but require high quality electron beams. Here the authors show how to generate and preserve ultrabright electron beams from plasma-based accelerators for ultra-compact, high-brightness X-ray ...
