Radiation Hydrodynamics and extended MHD studies in inertial confinement fusion and laser driven high energy density physics.

该项目将在很大程度上基于在三个主流选项（间接、直接和磁驱动）内探索ICF等离子体点火的不同选项，特别是评估将概念扩展到下一代设施（包括升级的NIF）。最初的重点将是探索直接驱动的新设计的优势（例如，目前正在Omega上探索的来自机器学习研究的新脉冲形状），并基于物理学理解性能提高背后的原因，以及扩展到更大设施的潜在影响。另一个近期的重点是在NIF上模拟极地直接驱动拍摄。虽然这些目标可能不会被证明是点燃和传播燃烧的最终途径，但它们目前与间接驱动的创纪录产量相匹配，并且是探索NIF规模直接驱动选项和研究其他方法的一些物理问题的非常有用的平台，例如磁场对电子热流的影响。除了ICF的工作，我们还设想与LLE罗切斯特，麻省理工学院，密歇根大学和约克大学的小组合作设计其他高能量密度物理实验。这些实验使我们能够在更受控的实验中研究ICF胶囊中涉及的一些更基本的物理学，并帮助设计新的诊断方法，然后可以在胶囊内爆实验中实施。

The project will be largely based on exploring the different options for ignition of an ICF plasma within the three mainstream options (indirect, direct and magnetic drive) and in particular evaluating scaling of concepts to next generation facilities (including an upgraded NIF). The initial focus will be on exploring the advantages of novel designs in direct drive (for example the new pulse shapes currently being explored on Omega derived from machine learning studies) and arriving at a physics based understanding of the reasons behind the improved performance, as well as the potential implications for scaling to larger facilities. Another near term focus would be modelling polar direct drive shots on NIF. While these targets may not prove to be the final route to ignition and propagating burn, they currently match the record yields from indirect drive and are a very useful platform for exploring the option for direct drive at the NIF scale and studying some of the physics issues of other approaches, for example the effects of magnetic fields on electron heat flow. In addition to the work on ICF, we also envisage working on the design of other high energy density physics experiments in direct drive in collaboration with groups at LLE Rochester, MIT, University of Michigan and University of York. These are experiments which allow us to investigate some of the more fundamental physics involved in ICF capsules, in a more controlled experiments as well as helping the design of novel diagnostic approaches which can then be implemented in capsule implosion experiments.
