We report on measurements of the ion-electron energy-transfer cross section utilizing low-velocity ion stopping in high-energy-density plasmas at the OMEGA laser facility. These measurements utilize a technique that leverages the close relationship b

Review of the first charged-particle transport coefficient comparison workshop

We present the results of the first Charged-Particle Transport Coefficient Code Comparison Workshop, which was held in Albuquerque, NM October 4-6, 2016. In this first workshop, scientists from eight institutions and four countries gathered to compar

Publikováno v: Journal of Verification, Validation and Uncertainty Quantification. 6

This paper presents the assessment of the performance of nine discretization uncertainty estimates based on grid refinement studies including methods that use grid triplets and others that use a largest number of data points, which in this study was

Cryogenically cooled inertial confinement fusion capsule designs are suitable for studies of reaction-in-flight (RIF) neutrons. RIF neutrons occur when energetically up-scattered ions undergo DT reactions with a thermal ion in the plasma, producing n

We present the calculations and preliminary results from experiments on the Omega laser facility using d-H3e filled plastic capsule implosions in gold Hohlraums. These experiments aim to develop a technique to measure shell ρr and capsule unablated

Publikováno v: Review of Scientific Instruments. 77:10E711

If x-radiation penetrates the ablator of an ignition capsule too deeply or too little, ignition can fail. Typically an ablator areal density of ∼0.2g∕cm2 remains at ignition time. 20% more or less flux in the final pulse of radiation driving the
