TL;DR: The Z-pinch dynamic hohlraum is an x-ray source for high energy-density physics studies that is heated by a radiating shock to radiation temperatures >200 eV and the time-dependent 300-400 eV electron temperature and 15-35 mg/cc density have been measured for the first time using space-resolved Si tracer spectroscopy.

TL;DR: In this paper, the scaling laws of electron-impact multiple ionization cross sections and expressions for the cross sections for arbitrary atoms and ions are presented on the basis of average experimental data.

TL;DR: Detailed spectroscopic diagnostics of the stagnating plasma in two disparate z pinches allow, for the first time, the examination of the plasma properties within a 1D shock wave picture, demonstrating a good agreement with this picture.

TL;DR: The time history of the local ion kinetic energy in a stagnating plasma was determined from Doppler-dominated line shapes, and it is found that throughout most of the stagnation period the ion thermal energy constitutes a small fraction of the total ion kineticEnergy.

TL;DR: The ion-kinetic energy throughout K emission in a stagnating plasma was determined from the Doppler contribution to the shapes of optically thin lines, and is shown to account for the total radiation.
