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. [...]

Single Molecule Imaging Using X-ray Free Electron Lasers
X-ray Free Electron Lasers / Boutet, Sébastien (Editor) ; Cham : Springer International Publishing, 2018, Chapter 14 ; ISBN: 978-3-030-00550-4 ; doi:10.1007/978-3-030-00551-1 Cham : Springer International Publishing 401-426 () [10.1007/978-3-030-00551-1_14]  GO
The potential to image single molecules in action with a resolution sufficiently high to reveal atomic information at room temperature without the need for crystallization is one of the most exciting applications of X-ray free electron lasers. Significant progress has been made towards this goal over the past years. [...]

X-ray Emission Spectroscopy at X-ray Free Electron Lasers: Limits to Observation of the Classical Spectroscopic Response for Electronic Structure Analysis
X-ray free electron lasers (XFELs) provide ultrashort intense X-ray pulses suitable to probe electron dynamics but can also induce a multitude of nonlinear excitation processes. These affect spectroscopic measurements and interpretation, particularly for upcoming brighter XFELs. [...]

Processing serial crystallography data with CrystFEL : a step-by-step guide
This article provides a step-by-step guide to the use of the CrystFEL software for processing serial crystallography data from an X-ray free-electron laser or a synchrotron light source. Whereas previous papers have described the theory and algorithms and their rationale, this paper describes the steps to be performed from a user perspective, including command-line examples..

Phase retrieval for arbitrary Fresnel-like linear shift-invariant imaging systems suitable for tomography
Biomedical optics express 9(9), 4390 - 4400 () [10.1364/BOE.9.004390]  GO
We present a generalization of the non-iterative phase retrieval in X-ray phase contrast imaging applicable for an arbitrary linear shift-invariant (LSI) imaging system with a non-negligible amount of free space propagation (termed as Fresnel-like). Our novel approach poses no restrictions on the propagation distance between optical elements of the system [...]

Reproducibility of single protein explosions induced by X-ray lasers
Single particle imaging (SPI) using X-ray pulses has become increasingly attainable with the advent of high-intensity free electron lasers. Eliminating the need for crystallized samples enables structural studies of molecules previously inaccessible by conventional crystallography. [...]

Few-femtosecond extreme-ultraviolet pulses fully reconstructed by a ptychographic technique
Optics express 26(6), 6771 - 6784 () [10.1364/OE.26.006771]  GO
Sub-10-fs pulses tunable in the extreme-ultraviolet (XUV) spectral region are particularly important in many research fields: from atomic and molecular spectroscopy to the study of relaxation processes in solids and transition phase processes, from holography to free-electron laser injection. A crucial prerequisite for all applications is the accurate measurement of the temporal characteristics of these pulses [...]

Author Correction: Supersaturation-controlled microcrystallization and visualization analysis for serial femtosecond crystallography
Time-resolved serial femtosecond crystallography with X-ray free electron laser (XFEL) holds the potential to view fast reactions occurring at near-physiological temperature. However, production and characterization of homogeneous micron-sized protein crystals at high density remain a bottleneck, due to the lack of the necessary equipments in ordinary laboratories. [...]

Strong enrichment of atmospherically relevant organic ions at the aqueous interface: the role of ion pairing and cooperative effects
Surface affinity, orientation and ion pairing are investigated in mixed and single solute systems of aqueous sodium hexanoate and hexylammonium chloride. The surface sensitive X-ray photoelectron spectroscopy technique has been used to acquire the experimental results, while the computational data have been calculated using molecular dynamics simulations [...]
