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…
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…
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…
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…
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…
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…
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…
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…
Evidence of free-bound transitions in warm dense matter and their impact on equation-of-state measurements
Maximilian P. Böhme, Luke B. Fletcher, Tilo Döppner +8
Warm dense matter (WDM) is now routinely created and probed in laboratories around the world, providing unprecedented insights into conditions achieved in stellar atmospheres, plan…
X-ray Thomson scattering absolute intensity from the f-sum rule in the imaginary-time domain
Tobias Dornheim, Tilo Döppner, Andrew D. Baczewski +10
We present a formally exact and simulation-free approach for the normalization of X-ray Thomson scattering (XRTS) spectra based on the f-sum rule of the imaginary-time correlation…
