“…The induced local plasma current, J and magnetic flux density, B, produces a strong J × B Lorentz force which accelerates a highly energetic plasma to stagnate on axis in about 100 ns. This stagnation and subsequent magnetic energy conversion produces an intense 10 ns X-ray radiation pulse [43,53]. The intense X-ray pulse can then be used for radiation-material interaction studies [44,42,45], environments for indirect drive inertial confinement fusion (ICF) applications [42,45,43], or for pursuing laboratory-based astrophysics environments [45,51,54,15,9,22].…”

“…Then we present the experimental constraints for high density plasmas and the SB possibilities in these more complex situations. We will also focus on ICF plasmas obtained on lasers or Z pinches facilities~Woolsey et al Stygar et al, 2004;Bailey et al, 2004!. However, it is important to check SB theoretical predictions in some experiments where other diagnostic can simultaneously provides determination of density.…”

On Stark broadening as a tool for diagnostics of high density plasmas

We present the current status-of-the-art in Stark broadening theory as a theoretical basis for diagnostics of low temperature plasmas in gas discharges, and of high temperature laser produced or z-pinch dense plasmas. The diagnostics abilities vary depending on the parameters of the gas discharges, or on the range of intensity, and duration of the laser or z-pinch pulses. In the case of high temperature plasmas, besides the conventional diagnostics based on the Stark broadening, the contemporary possibilities of UV and XUV interferometry for plasma density measurements and of tomography reconstruction of the macroscopic gradients of temperature and densities in laser produced plasmas are discussed.

SUMMARYIn this paper, a phenomenological model for a magnetic drive source term for the momentum and total energy equations of the Euler system is described. This body force term is designed to produce a Z-pinch like implosion that can be used in the development and evaluation of shock-hydrodynamics algorithms that are intended to be used in Z-pinch simulations. The model uses a J×B Lorentz force, motivated by a 0-D analysis of a thin shell (or liner implosion), as a source term in the equations and allows for arbitrary current drives to be simulated. An extension that would include the multi-physics aspects of a proposed combined radiation hydrodynamics (rad-hydro) capability is also discussed. The specific class of prototype problems that are developed is intended to illustrate aspects of liner implosions into a near vacuum and with idealized pre-fill plasma effects. In this work, a high-resolution flux-corrected-transport method implemented on structured overlapping meshes is used to demonstrate the application of such a model to these idealized shock-hydrodynamic studies. The presented results include an asymptotic solution based on a limiting-case thin-shell analytical approximation in both (x, y) and (r, z). Additionally, a set of more realistic implosion problems that include density profiles approximating plasma pre-fill and a set of perturbed liner geometries that excite a hydro-magnetic like Rayleigh-Taylor instability in the implosion dynamics are demonstrated. Finally, as a demonstration of including and evaluating multiphysics effects in the Euler system, a simple radiation model is included and self-convergence results for two types of (r, z) implosions are presented.
