Coupling kinetic solutions of laser-plasma interactions to large-scale fluid simulations will help optimise experiments aimed at achieving thermonuclear fusion driven by lasers Aims and objectivesThe project will involve coupling the output the from the LPSE code that simulates the laser-plasma interactions including kinetic effects to Warwick's radiation-hydrodynamic code (Odin). The kinetic effects will be included via the LPSE code2. Specifically we would like to know the sensitivity of LPSE simulations to non-linear limiters and how these uncertainties affect the accuracy of Odin simulations by coupling the LPSE output into Odin's fast-electron models. This work therefore covers multi-scale modelling, uncertainty quantification and significant amounts of software development. This will be the first code suite which directly couple the fast-electrons predicted from laser plasma codes such as LPSE into a radiation-hydrodynamics code.This falls within the Plasmas and Lasers area of the Physical Sciences Theme of EPSRC the Plasmas and Lasers area of the Energy Theme

将激光-等离子体相互作用的动力学解耦合到大尺度流体模拟将有助于优化旨在实现激光驱动热核聚变的实验。目的和目标该项目将涉及将模拟激光-等离子体相互作用的LPSE代码的输出耦合到沃里克的辐射流体动力学代码（Odin）。动力学效应将通过LPSE代码2纳入。具体来说，我们想知道LPSE模拟对非线性限制器的敏感性，以及这些不确定性如何通过将LPSE输出耦合到Odin的快电子模型中来影响Odin模拟的准确性。因此，这项工作包括多尺度建模、不确定性量化和大量软件开发。这将是第一个直接将激光等离子体程序（如LPSE）预测的快电子耦合到辐射流体动力学程序中的程序集。这福尔斯EPSRC物理科学主题的等离子体和激光领域，能源主题的等离子体和激光领域
