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…
Phase transitions of FeO under laser shock compression
A. Amouretti, C. Crépisson, S. Azadi +22
We present in-situ x-ray diffraction and velocity measurements of FeO under laser shock compression at pressures between 38-116 GPa. None of the phases reported by static c…
Resonant inelastic x-ray scattering in warm-dense Fe compounds beyond the SASE FEL resolution limit
Alessandro Forte, Thomas Gawne, Karim K. Alaa El-Din +19
Resonant inelastic x-ray scattering (RIXS) is a widely used spectroscopic technique, providing access to the electronic structure and dynamics of atoms, molecules, and solids. Howe…
Slip competition and rotation suppression in tantalum and copper during dynamic uniaxial compression
Patrick G. Heighway, Justin S. Wark
When compressed, a metallic specimen will generally experience changes to its crystallographic texture due to plasticity-induced rotation. Ultrafast x-ray diffraction techniques ma…
Crystal plasticity finite element simulation of lattice rotation and x-ray diffraction during laser shock-compression of Tantalum
P. Avraam, D. McGonegle, P. G. Heighway +7
Wehrenberg et. al. [Nature 550 496 (2017)] used ultrafast in situ x-ray diffraction at the LCLS x-ray free-electron laser facility to measure large lattice rotations resulting from…
Atomistic deformation mechanism of silicon under laser-driven shock compression
S. Pandolfi, S. Brennan Brown, P. G. Stubley +10
Silicon (Si) is one of the most abundant elements on Earth, and it is the most important and widely used semiconductor, constituting the basis of modern electronic devices. Despite…
