Study of extreme ultraviolet laser ablation for fusion applications

我的导师是Erik Wagenaars博士和Greg Tallents教授，我的研究是了解从EUV到IR的激光烧蚀，用于间接和直接驱动ICF。聚变反应将较轻的原子（如氢）结合在一起，形成更大的原子，并释放出大量的能量。聚变能旨在利用这种反应生产可再生能源。惯性约束聚变是实现聚变能的途径之一，本项目就处于这一领域。其主要概念是通过使用高功率激光加热和压缩燃料靶来实现聚变。激光烧蚀是惯性约束核聚变的关键过程之一，即强激光与靶相互作用，使靶产生等离子体。该项目旨在研究固体材料激光烧蚀背后的基本物理学，特别关注从IR到EUV的波长函数的差异。它将涉及实验以及计算建模调查。等离子体诊断，如光学发射光谱，时间分辨成像，阴影和干涉测量将用于研究烧蚀过程的属性。

My supervisors are Dr Erik Wagenaars and Prof Greg Tallents and my research is about understanding laser ablation from EUV to IR for indirect and direct drive ICF.Fusion reactions combine lighter atoms, such as hydrogen, together to form larger ones and release significant amounts of energy. Fusion energy aims to use such reactions for the production of renewable energy. Inertial Confinement Fusion is one of the approaches to achieve fusion energy and this project sits in this area. The main concept is to achieve fusion by heating and compressing a fuel target using high-power lasers. Laser ablation, i.e. a high-power laser interacts with a target, turning it into a plasma, is one of the key processes in Inertial Confinement Fusion. This project aims to study the fundamental physics behind laser ablation of solid materials, in particular focusing on the differences as a function of wavelength, from IR to EUV. It will involve both experimental as well as computational modelling investigations. Plasma diagnostics such as optical emission spectroscopy, time-resolved imaging, shadowgraphy and interferometry will be used the study the properties of the ablation process.
