Journal ArticleDOI
Fabrication and characterization of joined silicon carbide cylindrical components for nuclear applications
TL;DR: In this paper, a cylindrical SiC-SiC composite tube sealed with a butted scarf endplug provides out-of-pile strength and permeability performance that meets light water reactor design requirements.
Journal ArticleDOI
Absolute measurements of x-ray backlighter sources at energies above 10 keVa)
Brian Maddox,H.-S. Park,Bruce Remington,C. Chen,Sophia Chen,Shon Prisbrey,Andrew Comley,Christina Back,Csilla I. Szabo,John F. Seely,Uri Feldman,Lawrence T. Hudson,Stephen M. Seltzer,M. J. Haugh,Z. A. Ali +14 more
TL;DR: In this paper, the conversion efficiency of short and long-pulse driven Mo and Ag line-emission backlighters at 17 and 22 keV was measured to investigate the crossover region between short- and longpulse conversion efficiency, and a comparison between the measured Mo x-ray spectrum and calculations using an atomic physics code suggests that the line emission is due to thermal emission from N-like Mo atoms.
Journal ArticleDOI
Fill-Tube-Induced Mass Perturbations on X-Ray-Driven, Ignition-Scale, Inertial-Confinement-Fusion Capsule Shells and the Implications for Ignition Experiments
Guy R. Bennett,Mark Herrmann,M. J. Edwards,Brian Spears,Christina Back,Eric Breden,Peggy Jo Christenson,M. E. Cuneo,K L Dannenburg,C Frederick,K. L. Keller,T. D. Mulville,A. Nikroo,Kyle Peterson,John L. Porter,C. Russell,Daniel Sinars,Ian C. Smith,R. M. Stamm,Roger Alan Vesey +19 more
TL;DR: Simulations compare well with observation, whence it is corroborated that Delta m' arises from early x-ray shadowing by the tube rather than tube mass coupling to the shell, and inferred that 10-20 microm tubes will negligibly affect fusion yield on a full-ignition facility.
Journal ArticleDOI
Interpretation of hot and dense absorption spectra of a near-local-thermodynamic-equilibrium plasma by the super-transition-array method
A. Bar-Shalom,J. Oreg,John F. Seely,U. Feldman,Charles M. Brown,B. A. Hammel,Richard W. Lee,Christina Back +7 more
TL;DR: The super-transition-array model is shown to be a very convenient tool for the interpretation of near-local-thermodynamic-equilibrium hot and dense plasmas and remarkably good agreement between the theory and the experiment is obtained for the Ni 2{ital p}-3{ital d} spectrum.
Journal ArticleDOI
Low stimulated Brillouin backscatter observed from large, hot plasmas in gas-filled Hohlraums.

MacGowan,D. S. Montgomery,D. H. Munro,Deanna Marie Pennington,T. D. Shepard,Gary Stone,L. J. Suter,E. A. Williams +20 more
TL;DR: Stimulated Brillouin scattering (SBS) has been measured from hohlraums with plasma conditions similar to those predicted for high gain targets with a variety of beam smoothing implementations.
