XFEL Imaging Techniques for High Energy Density and Inertial Fusion Energy Research at HED-HiBEF
Alejandro Laso Garcia, Mikhail Mishchenko, Victorien Bouffetier +53
The imaging platform developed at the High Energy Density - Helmholtz International Beamline for Extreme Fields (HED-HiBEF) instrument at the European XFEL and its applications to…
Probing laser-driven surface and subsurface dynamics via grazing-incidence XFEL scattering and diffraction
Lisa Randolph, Özgül Öztürk, Dmitriy Ksenzov +34
We demonstrate a grazing-incidence x-ray platform that simultaneously records time-resolved grazing-incidence small-angle x-ray scattering (GISAXS) and grazing-incidence x-ray diff…
Strong geometry dependence of the X-ray Thomson Scattering Spectrum in single crystal silicon
Thomas Gawne, Zhandos A. Moldabekov, Oliver S. Humphries +17
We report on results from an experiment at the European XFEL where we measured the x-ray Thomson scattering (XRTS) spectrum of single crystal silicon with ultrahigh resolution. Com…
Formation of high-aspect-ratio nanocavity in LiF crystal using a femtosecond of x-ray FEL pulse
Sergey S. Makarov, Sergey A. Grigoryev, Vasily V. Zhakhovsky +30
Sub-picosecond optical laser processing of metals is actively utilized for modification of a heated surface layer. But for deeper modification of different materials a laser in the…
Shock-driven amorphization and melt in FeO
Céline Crépisson, Alexis Amouretti, Marion Harmand +28
We present measurements on FeO amorphization and melt under laser-driven shock compression up to 209(10) GPa via time-resolved in situ x-ray diffraction. At 122(3) GPa, a d…
Effects of Mosaic Crystal Instrument Functions on X-ray Thomson Scattering Diagnostics
Thomas Gawne, Hannah Bellenbaum, Luke B. Fletcher +36
Mosaic crystals, with their high integrated reflectivities, are widely-employed in spectrometers used to diagnose high energy density systems. X-ray Thomson scattering (XRTS) has e…
X-ray Microscopy and Talbot Imaging with the Matter in Extreme Conditions X-ray Imager at LCLS
Eric Galtier, Hae Ja Lee, Dimitri Khaghani +25
The last decade has shown the great potential that X-ray Free Electron Lasers (FEL) have to study High Energy Density (HED) physics. Experiments at FELs have made significant break…
(Sub-)picosecond surface correlations of femtosecond laser excited Al-coated multilayers observed by grazing-incidence x-ray scattering
Lisa Randolph, Mohammadreza Banjafar, Toshinori Yabuuchi +22
Femtosecond high-intensity laser pulses at intensities surpassing can generate a diverse range of functional surface nanostructures. Achieving prec…
The importance of temperature-dependent collision frequency in PIC simulation on nanometric density evolution of highly-collisional strongly-coupled dense plasmas
Mohammadreza Banjafar, Lisa Randolph, Lingen Huang +17
Particle-in-Cell (PIC) method is a powerful plasma simulation tool for investigating high-intensity femtosecond laser-matter interaction. However, its simulation capability at high…
X-ray induced grain boundary formation and grain rotation in Bi2Se3
Kento Katagiri, Bernard Kozioziemski, Eric Folsom +24
Optimizing grain boundary characteristics in polycrystalline materials can improve their properties. Many processing methods have been developed for grain boundary manipulation, in…
