X-ray crystallography provides the vast majority of macromolecular structures, but the success of the method relies on growing crystals of sufficient size. In conventional measurements, the necessary increase in X-ray dose to record data from crystals that are too small leads to extensive damage before a diffraction signal can be recorded. It is… (More)
X-ray lasers offer new capabilities in understanding the structure of biological systems, complex materials and matter under extreme conditions. Very short and extremely bright, coherent X-ray pulses can be used to outrun key damage processes and obtain a single diffraction pattern from a large macromolecule, a virus or a cell before the sample explodes and… (More)
The diversity of nanoparticle shapes generated by condensation from gaseous matter reflects the fundamental competition between thermodynamic equilibration and the persistence of metastable configurations during growth. In the kinetically limited regime, intermediate geometries that are favoured only in early formation stages can be imprinted in the finally… (More)
Explosions of methane clusters driven by intense XFEL pulses were studied during the first experiments at LCLS. Ion fragment distribution dynamics depends strongly on wavelength and pulse width.
Interaction of ultrashort — X-rays laser with xenon doped methane clusters have been studied in the first experiments at LCLS with time-of-flight technique. Xe doping affects the explosion of the CH<inf>4</inf> clusters.
Cluster explosion in ultrashort intense X-ray laser fields have been studied in first experiments at the LCLS with time-of flight techniques. Ion charge states and kinetic energy spectra indicate hydrodynamic and Coulombic plasma expansion contributions.
