Measurement of ion acceleration and diffusion in a laser-driven magnetized plasma
J. T. Y. Chu, J. W. D. Halliday, C. Heaton +25
Here we present results from an experiment performed at the GSI Helmholtz Centre for Heavy Ion Research. A mono-energetic beam of chromium ions with initial energies of …
Design of experiments characterising heat conduction in magnetised, weakly collisional plasma
T. A. Vincent, P. Ariyathilaka, L. Creaser +15
Heat conduction in weakly collisional, magnetised plasma is challenging to model accurately due to multifaceted physics governing heat-carrying electrons, including microinstabilit…
Characterization and automated optimization of laser-driven proton beams from converging liquid sheet jet targets
G. D. Glenn, F. Treffert, H. Ahmed +31
Compact, stable, and versatile laser-driven ion sources hold great promise for applications ranging from medicine to materials science and fundamental physics. While single-shot so…
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…
Bounding elastic photon-photon scattering at MeV using a laser-plasma platform
R. Watt, B. Kettle, E. Gerstmayr +36
We report on a direct search for elastic photon-photon scattering using x-ray and photons from a laser-plasma based experiment. A gamma photon beam produced by a laser wakefie…
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…
