X-ray thermal diffuse scattering as a texture-robust temperature diagnostic for dynamically compressed solids
P. G. Heighway, D. J. Peake, T. Stevens +119
We present a model of x-ray thermal diffuse scattering (TDS) from a cubic polycrystal with an arbitrary crystallographic texture, based on the classic approach of Warren. We compar…

Observation of Body-Centered Cubic Iron above 200 Gigapascals
Zuzana Konopkova, Eric Edmund, Orianna B Ball +34
The crystallographic structure of iron under extreme conditions is a key benchmark for cutting-edge experimental and numerical methods. Moreover, it plays a crucial role in underst…

Femtosecond temperature measurements of laser-shocked copper deduced from the intensity of the x-ray thermal diffuse scattering
J. S. Wark, D. J. Peake, T. Stevens +122
We present 50-fs, single-shot measurements of the x-ray thermal diffuse scattering (TDS) from copper foils that have been shocked via nanosecond laser-ablation up to pressures abov…
