“…SFX can resolve room-temperature protein structures to better than 2 Å resolution on very small crystals [19,131], which expands the technique to include samples that are difficult to crystallize, such as membrane proteins [139] and 2D protein crystals [140,141]. A complementary technique with similar technical requirements to SFX that will also be possible at Alvra is wide-angle X-ray scattering (WAXS, also called X-ray diffuse scattering or XDS), where the sample under investigation is a liquid solution [142]. The result of the X-ray scattering measurement is powder-diffraction-like rings, containing information on the pair-distribution function of the sample [143,144].…”

The SwissFEL X-ray Free Electron Laser (XFEL) facility started construction at the Paul Scherrer Institute (Villigen, Switzerland) in 2013 and will be ready to accept its first users in 2018 on the Aramis hard X-ray branch. In the following sections we will summarize the various aspects of the project, including the design of the soft and hard X-ray branches of the accelerator, the results of SwissFEL performance simulations, details of the photon beamlines and experimental stations, and our first commissioning results.

A method for the analysis of time-resolved x-ray absorption near edge structure (XANES) spectra is proposed. It combines principal component analysis of the series of experimental spectra, multidimensional interpolation of theoretical XANES as a function of structural parameters, and ab initio XANES calculations. It allows to determine the values of structural parameters for intermediates of chemical reactions and the concentrations of different states as a function of time. This approach is tested using numerically generated data and its possibilities and limitations are discussed. The application of this method to a reaction with methylrhenium trioxide catalyst in solution, for which experimental data were measured using stopped-flow energy-dispersive x-ray absorption spectroscopy technique, is demonstrated. Possibilities and limitations of this experimental technique are also discussed.
