Ideal Laser Beam Propagation through high temperature ignition hohlraum plasmas
Dustin Froula,Laurent Divol,N. Meezan,S. N. Dixit,J. D. Moody,B. B. Pollock,James Ross,Siegfried Glenzer +7 more
TL;DR: Scaling of the electron temperature in the plasma shows that the plasma becomes transparent for uniform electron temperatures above 3 keV, consistent with linear theory thresholds for both filamentation and backscatter instabilities inferred from detailed hydrodynamic simulations.
Journal ArticleDOI
Measurements of Suprathermal Electrons in Hohlraum Plasmas with X-Ray Spectroscopy
Siegfried Glenzer,F. B. Rosmej,Richard W. Lee,Christina Back,Kent Estabrook,B. J. MacGowan,T. D. Shepard,Robert Turner +7 more
TL;DR: In this article, nonthermal excitation of atomic states by suprathermal electrons was observed for the first time within inertial confinement fusion hohlraum plasmas.
Journal ArticleDOI
Demonstration of Enhanced Radiation Drive in Hohlraums Made from a Mixture of High-Z Wall Materials
Jochen Schein,Ogden Jones,Mordecai D. Rosen,Eduard Dewald,Siegfried Glenzer,J. Gunther,Bruce Hammel,Otto Landen,L. J. Suter,R. J. Wallace +9 more
TL;DR: In this article, the authors present results from experiments, numerical simulations and analytic modeling, demonstrating enhanced hohlraum performance with high-Z mixtures (cocktails) and demonstrate that a National Ignition Facility ignition hohlrahum made of a U:Au:Dy cocktail should have a 17% reduction in wall losses compared to a similar gold hohlrasum.
Journal ArticleDOI
Modeling the nonlinear saturation of stimulated Brillouin backscatter in laser heated plasmas
Laurent Divol,Richard Berger,Bruce I. Cohen,E. A. Williams,A. B. Langdon,Barbara F. Lasinski,Dustin Froula,Siegfried Glenzer +7 more
TL;DR: In this paper, two examples of reduced models of nonlinear effects that are included in a fluid model are described, using a nonlinear damping representing the saturation of the amplitude of acoustic waves in the fluid regime (i.e., weak Landau damping).
