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…
Scaling of thin wire cylindrical compression after 100 fs Joule surface heating with material, diameter and laser energy
L. Yang, M. -L. Herbert, C. Bähtz +32
We present the first systematic experimental validation of return-current-driven implosion scaling in micrometer-sized wires irradiated by femtosecond laser pulses. Employing XFEL-…
Shake-off in XFEL heated solid density plasma
G. O. Williams, L. Ansia, M. Makita +25
In atoms undergoing ionisation, an abrupt re-arrangement of free and bound electrons can lead to the ejection of another bound electron (shake-off). The spectroscopic signatures of…
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…
