Mitigating the Joint Feature in Double Shell Implosion Simulations
Published 09/12/2021
2021 IEEE International Conference on Plasma Science (ICOPS), 1 - 1
Double shell capsules are an attractive alternative in inertial confinement fusion experiments due to their potential for achieving a low-convergence, robust burn 1 . However, symmetry degradation and accompanying reduced fuel confinement plagues these systems due to the joint between the two hemispheres of the outer shell. The gap widens during irradiation and this perturbation grows and imprints onto the inner shell during the collision. xRAGE Eulerian radiation-hydrodynamic simulations predict significant reductions in deuterium-tritium fusion yields compared to joint-less simulations when the depth of the outer joint is increased. We demonstrate that the technique of plating the insides of the outer gap with gold can mitigate the impact of this feature. Gold-plating in quantities comparable to or exceeding the "missing" outer shell mass shows promise toward restoring both implosion symmetry and yield closer to the joint-less levels 2 . The shape and symmetry retention in the outer and inner shells is captured in high-energy x-ray synthetic radiographs.

The siderophilic, thermophilic Leptolyngbyaceae cyanobacterium JSC-12 was isolated from a microbial mat in an iron-depositing hot spring. Here, we report the high-quality draft genome sequence of JSC-12, which may help elucidate the mechanisms of resistance to extreme iron concentrations in siderophilic cyanobacteria and lead to new remediation biotechnologies.

Detrimental effects and mitigation of the joint feature in double shell implosion simulations

Double shell capsules provide an attractive option in inertial confinement fusion experiments due to their potential for achieving a low-convergence, robust burn. However, these designs suffer from symmetry degradation and accompanying reduced fuel confinement due to the currently necessary joint between the two hemispheres of the outer shell. The gap widens as a result of the excess ablation pressure produced by x rays that penetrate the joint during the drive phase, and this perturbation grows and imprints onto the inner shell during the collision. xRAGE Eulerian radiation-hydrodynamic simulations predict significant reductions in deuterium-tritium fusion yields compared to joint-less simulations when the depth of the outer joint is increased, whereas the performance is less sensitive to the depth of the inner gap. Here we examine the technique of plating the insides of the outer gap with a high-Z material to mitigate the impact of this feature. Gold-plating in quantities comparable to or exceeding the "missing" outer shell mass shows promise toward restoring both implosion symmetry and yield closer to the joint-less levels, and synthetic diagnostics suggest that high-energy x-ray radiographs can capture this shape retention of the inner and outer shells in experiments.
