“…The present findings may validate the 'diffraction-beforedestruction' approach of single bio-macromolecules and protein microcrystals, as long as the hydrogen atoms can be neglected, and also suggest the importance of understanding influences of charge dynamics that occur within the X-ray-pulse duration to the X-ray scattering. We have also been conducting spectroscopic experiments using soft-X-ray FEL [49][50][51] and X-ray diffraction experiments [52][53][54][55] at SACLA, though these attempts were not described in the present review article. We believe that electronic and structural dynamics in various forms of matter will be investigated extensively employing XFELs all over the world and we hope that our attempts described in this article will contribute to such investigations.…”

X-ray free electron lasers (XFELs) deliver intense, coherent, femtosecond X-ray laser pulses. They are opening new research fields of studying ultrafast electronic and structural dynamics in various forms of matter and interaction of intense and short X-ray pulses with matter. For such studies, atoms, molecules, and atomic clusters in the gas phase may provide us with ideal platforms as various levels of experimental methods and theory are within reach. Developing experimental setups of electron and ion spectroscopies for gas-phase experiments at SACLA, a low-repetition rate X-ray free electron laser facility in Japan, we have studied the interaction of intense, short X-ray pulses with atoms, molecules, and atomic clusters. Via these experimental investigations and modelling efforts, we gain insight into the interaction of these intense pulses with the single-particle targets and extracted the information about how they are modified during the X-ray pulse duration. We summarize these studies in the present review. The information reported here will be important for any XFEL applications as the scattering signal used to image any targets may be strongly influenced by the XFEL-induced dynamics that occur in the target within the pulse duration.

“…The experiments were performed at experimental hutch 2 of beamline 3 (Yabashi et al, 2017) of the SACLA. For details of the experimental setup, see also our previous publication (Nishiyama et al, 2019). The SACLA generated 1.1 Å X-ray pulses at a repetition rate of 30 Hz.…”

Characterizing and controlling the uniformity of nanoparticles is crucial for their application in science and technology because crystalline defects in the nanoparticles strongly affect their unique properties. Recently, ultra-short and ultra-bright X-ray pulses provided by X-ray free-electron lasers (XFELs) opened up the possibility of structure determination of nanometre-scale matter with Å spatial resolution. However, it is often difficult to reconstruct the 3D structural information from single-shot X-ray diffraction patterns owing to the random orientation of the particles. This report proposes an analysis approach for characterizing defects in nanoparticles using wide-angle X-ray scattering (WAXS) data from free-flying single nanoparticles. The analysis method is based on the concept of correlated X-ray scattering, in which correlations of scattered X-ray are used to recover detailed structural information. WAXS experiments of xenon nanoparticles, or clusters, were conducted at an XFEL facility in Japan by using the SPring-8 Å ngstrom compact free-electron laser (SACLA). Bragg spots in the recorded single-shot X-ray diffraction patterns showed clear angular correlations, which offered significant structural information on the nanoparticles. The experimental angular correlations were reproduced by numerical simulation in which kinematical theory of diffraction was combined with geometric calculations. We also explain the diffuse scattering intensity as being due to the stacking faults in the xenon clusters.

“…Examples range from biologically relevant specimen such as single viruses (4,6) or macromolecules (7) to atomic clusters (8)(9)(10), nanocrystals (11), and even such fragile and short-lived structures as aerosols (12) or superfluid helium nanodroplets (13,14). The extremely short pulses further allow time-resolved imaging of ultrafast dynamics in isolated nanoscale structures, which has opened up unprecedented possibilities for light-matter interaction studies (15)(16)(17)(18)(19)(20)(21)(22)(23)(24).…”

The structure and dynamics of isolated nanosamples in free flight can be directly visualized via single-shot coherent diffractive imaging using the intense and short pulses of x-ray free-electron lasers. Wide-angle scattering images encode three-dimensional (3D) morphological information of the samples, but its retrieval remains a challenge. Up to now, effective 3D morphology reconstructions from single shots were only achieved via fitting with highly constrained models, requiring a priori knowledge about possible geometries. Here, we present a much more generic imaging approach. Relying on a model that allows for any sample morphology described by a convex polyhedron, we reconstruct wide-angle diffraction patterns from individual silver nanoparticles. In addition to known structural motives with high symmetries, we retrieve imperfect shapes and agglomerates that were not previously accessible. Our results open unexplored routes toward true 3D structure determination of single nanoparticles and, ultimately, 3D movies of ultrafast nanoscale dynamics.
