Abstract
Understanding the evolution of extreme states of matter driven by relativistic laser-plasma interactions is a fundamental problem in high-field physics. This study analyzes time-resolved x-ray emission spectroscopy from petawatt-irradiated Nickel nanowire arrays to characterize the conditions achieved when scaling nanowire targets to relativistic intensities. A full time evolution of the plasma conditions is extracted from the experimental data and shows good agreement with computational studies.
