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…
Spectral Deconvolution without the Deconvolution: Extracting Temperature from X-ray Thomson Scattering Spectra without the Source-and-Instrument Function
Thomas Gawne, Alina Kononov, Andrew Baczewski +7
X-ray Thomson scattering (XRTS) probes the dynamic structure factor of the system, but the measured spectrum is broadened by the combined source-and-instrument function (SIF) of th…
HEART: A New X-Ray Tracing Code for Mosaic Crystal Spectrometers
Thomas Gawne, Sebastian Schwalbe, Thomas Chuna +3
We introduce a new open-source Python x-ray tracing code for modelling Bragg diffracting mosaic crystal spectrometers: High Energy Applications Ray Tracer (HEART). HEART's high mod…
Model-free Rayleigh weight from x-ray Thomson scattering measurements
Tobias Dornheim, Hannah M. Bellenbaum, Mandy Bethkenhagen +16
X-ray Thomson scattering (XRTS) has emerged as a powerful tool for the diagnostics of matter under extreme conditions. In principle, it gives one access to important system paramet…
Applying the Liouville-Lanczos Method of Time-Dependent Density-Functional Theory to Warm Dense Matter
Zhandos A. Moldabekov, Sebastian Schwalbe, Thomas Gawne +3
Ab initio modeling of dynamic structure factors (DSF) and related density response properties in the warm dense matter (WDM) regime is a challenging computational task. The DSF, co…
Towards Model-free Temperature Diagnostics of Warm Dense Matter from Multiple Scattering Angles
Hannah M. Bellenbaum, Benjamin Bachmann, Dominik Kraus +9
Warm dense matter (WDM) plays an important role in astrophysical objects and technological applications, but the rigorous diagnostics of corresponding experiments is notoriously di…
