A Momentum-Resolved X-ray Thomson Scattering Benchmark of Electronic-Response Models in Warm Dense Aluminium
Dmitrii S. Bespalov, Ulf Zastrau, Zhandos A. Moldabekov +58
The robust diagnosis of conditions generated in warm dense matter (WDM) experiments remains a persistent challenge. Here we describe the measurement of shock-compressed aluminium a…
Probing ultrafast heating and ionization dynamics in solid density plasmas with time-resolved resonant X-ray absorption and emission
Lingen Huang, Mikhail Mishchenko, Michal Šmíd +34
Heating and ionization are among the most fundamental processes in relativistic laser--solid interactions; however, their spatiotemporal evolution remains challenging to capture ex…
Methods for energy dispersive x-ray spectroscopy with photon-counting and deconvolution techniques
Alessandro Forte, Thomas Gawne, Oliver S. Humphries +3
Spectroscopic techniques are essential for studying material properties, but the small cross-sections of some methods may result in low signal-to-noise ratios (SNRs) in the collect…
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…
Bounds on heavy axions with an X-ray free electron laser
Jack W. D. Halliday, Giacomo Marocco, Konstantin A. Beyer +18
We present new exclusion bounds obtained at the European X-ray Free Electron Laser facility (EuXFEL) on axion-like particles (ALPs) in the mass range 10^{-3} eV < m_a < 10^4 eV. Ou…
Ultrahigh Resolution X-ray Thomson Scattering Measurements at the European XFEL
Thomas Gawne, Zhandos A. Moldabekov, Oliver S. Humphries +18
Using a novel ultrahigh resolution (eV) setup to measure electronic features in x-ray Thomson scattering (XRTS) experiments at the European XFEL in Germany, we have…
Cylindrical compression of thin wires by irradiation with a Joule-class short pulse laser
Alejandro Laso Garcia, Long Yang, Victorien Bouffetier +14
Equation of state measurements at Jovian or stellar conditions are currently conducted by dynamic shock compression driven by multi-kilojoule multi-beam nanosecond-duration lasers.…
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…
Dielectronic satellite emission from a solid-density Mg plasma: relationship to models of ionisation potential depression
G. Pérez-Callejo, T. Gawne, T. R. Preston +15
We report on experiments where solid-density Mg plasmas are created by heating with the focused output of the Linac Coherent Light Source x-ray free-electron-laser. We study the K-…
Visualizing Plasmons and Ultrafast Kinetic Instabilities in Laser-Driven Solids using X-ray Scattering
Paweł Ordyna, Carsten Bähtz, Erik Brambrink +27
Ultra-intense lasers that ionize and accelerate electrons in solids to near the speed of light can lead to kinetic instabilities that alter the laser absorption and subsequent elec…
Investigating Mechanisms of State Localization in Highly-Ionized Dense Plasmas
Thomas Gawne, Thomas Campbell, Alessandro Forte +14
We present the first experimental observation of K emission from highly charged Mg ions at solid density, driven by intense x-rays from a free electron laser. The presence of K…
A Rate Model of Electron Populations for Non-linear High-Fluence X-ray Absorption Near-Edge Spectra
Robin Y. Engel, Markus Scholz, Jan O. Schunck +1
Absorbing a focused, femtosecond X-ray pulse from a Free-Electron Laser (FEL) can lead to extreme electronic excitations in solids. This excitation drives changes of the electronic…
Unconventional localization of electrons inside of a nematic electronic phase
L. Farrar, Z. Zajicek, A. B. Morfoot +6
The magnetotransport behaviour inside the nematic phase of bulk FeSe reveals unusual multiband effects that cannot be reconciled with a simple two-band approximation proposed by su…
Electron Dynamics at High-Energy Densities in Nickel from Non-linear Resonant X-ray Absorption Spectra
Robin Y. Engel, Oliver Alexander, Kaan Atak +40
The pulse intensity from X-ray free-electron lasers (FELs) can create extreme excitation densities in solids, entering the regime of non-linear X-ray-matter interactions. We show L…
