Wavefront sensing at X-ray free-electron lasers
Here a direct comparison is made between various X-ray wavefront sensing methods with application to optics alignment and focus characterization at X-ray free-electron lasers (XFELs). Focus optimization at XFEL beamlines presents unique challenges due to high peak powers as well as beam pointing instability, meaning that techniques capable of single-shot measurement and that probe the wavefront at an out-of-focus location are desirable. [...]

Focusing of an Aerosolized Beam of Virus Particles with an Optical Funnel
EOS Optical Technologies: Optofluidics and Manufacturing, Tolerancing, and Testing of Optical Systems, MunichMunich, Germany, 24 Jun 2019 - 27 Jun 20192019-06-242019-06-27
X-ray free-electron lasers have enabled the possibility of “single particle imaging”, in which the morphology of aerosolized particles may be uncovered through lensless diffractive imaging using intense femtosecond x-ray pulses that “freeze” atomic motion. Diffraction patterns are produced from a stream of particles such as atmospheric aerosol particulates or viruses that are intercepted by x-ray pulses focused to a sub-micrometer spot. [...]

3D printed nozzles on a silicon fluidic chip
Serial femtosecond crystallography is a new method for protein structure determination utilizing intense and destructive X-ray pulses generatedby free-electron lasers. The approach requires the means to deliver hydrated protein crystals to a focused X-ray beam and replenish themat the repetition rate of the pulses [...]

Climbing the Data Mountain: Processing of SFX Data
X-ray Free Electron Lasers / Boutet, Sébastien (Editor) ; Cham : Springer International Publishing, 2018, Chapter 7 ; ISBN: 978-3-030-00550-4 ; doi:10.1007/978-3-030-00551-1 Cham : Springer International Publishing 209-233 () [10.1007/978-3-030-00551-1_7]  GO
Serial femtosecond crystallography experiments produce mountains of data that require FEL facilities to provide many petabytes of storage space and large compute clusters for timely processing of user data. The route to reach the summit of the data mountain requires peak finding, indexing, integration, refinement, and phasing. [...]

Sample Delivery Techniques for Serial Crystallography
X-ray Free Electron Lasers / Boutet, Sébastien (Editor) ; Cham : Springer International Publishing, 2018, Chapter 5 ; ISBN: 978-3-030-00550-4 ; doi:10.1007/978-3-030-00551-1 Cham : Springer International Publishing 109-184 () [10.1007/978-3-030-00551-1_5]  GO
In serial femtosecond crystallography (SFX), protein microcrystals and nanocrystals are introduced into the focus of an X-ray free electron laser (FEL) beam ideally one-by-one in a serial fashion. The high photon density in each pulse is the double-edged sword that necessitates the serial nature of the experiments. [...]
