Radiating shock measurements in the Z-pinch dynamic hohlraum.
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. The time-dependent 300-400 eV electron temperature and 15-35 mg/cc density of this shock have been measured for the first time using space-resolved Si tracer spectroscopy. The shock x-ray emission is inferred from these measurements to ex...
متن کاملHELIOS Benchmark Calculation: Radiation-Driven Capsule Implosion in Z-Pinch Dynamic Hohlraum
In this HELIOS benchmark simulation, a spherical capsule embedded in a low-density CH2 foam is imploded by an external radiation field. The parameters utilized in this benchmark simulation are taken from z-pinch-driven dynamic hohlraum experiments performed at the Z facility at Sandia National Laboratories [1]. The time-dependent hohlraum radiation field is constrained by on-axis XRD and bolome...
متن کاملK-shell radiation physics in low- to moderate-atomic-number z-pinch plasmas on the Z accelerator
Dense z-pinches produced by 100 ns implosions of wire arrays or gas puffs produce substantial soft X-ray power. One class of z-pinch radiation sources includes lowto moderate-atomic-number K-shell radiators, such as aluminum and iron. These loads are designed for 1–10 keV K-shell X-ray generation, and offer opportunities for crystal spectroscopy that can reveal fundamental properties of the pla...
متن کاملDesign of dynamic Hohlraum opacity samples to increase measured sample density on Z.
We are attempting to measure the transmission of iron on Z at plasma temperatures and densities relevant to the solar radiation and convection zone boundary. The opacity data published by us to date has been taken at an electron density about a factor of 10 below the 9×10(22)/cm(3) electron density of this boundary. We present results of two-dimensional (2D) simulations of the heating and expan...
متن کاملExplosive Z Pinch
We propose an explanation for the recently observed powerful contained explosion in a Z pinch experiment performed at Sandia National Laboratories. Our arguments are based on the assumption that a pure SU(2) Yang-Mills theory of scale ∼ 0.5MeV is responsible for the emergence of the electron and its neutrino.
