Astrophysically relevant QED plasmas laboratory

项目摘要

I have recently graduated from the University of Kent with an MPhys in Physics with Astrophysics. While completing my undergraduate studies, I became increasingly more interested in Plasma Physics and its real-world applications, particularly in Fusion Energy.The project I will undertake at York is entitled 'Astrophysically-relevant QED plasmas in the laboratory', supervised by Dr Kate Lancaster and Dr Chris Ridgers. The project focuses on creating quantum electrodynamic (QED) plasmas using new multi-PW lasers. This increase in laser intensity will allow for new light-matter interactions to be observed, mainly considering cases where electromagnetic fields are so strong that QED plasmas are created. The plasmas are governed by ultra-relativistic plasma processes that alter the behaviour of the plasma entirely; we move away from classical processes and toward quantum effects. There has been minimal experimental work undertaken in this area, so QED plasmas are relatively unexplored experimentally. While the underlying physics of this new regime is almost completely unexplored in the laboratory the x-rays could be very useful for radiography of dense materials such as compressed inertial confinement cores and the ions could be used for novel fast ignition fusion schemes. The project will be a combination of laboratory and experimental work, and simulations to explore this new plasma regime.

我最近从肯特大学毕业，获得了物理学与天体物理学硕士学位。在完成本科学习的同时，我对等离子体物理学及其现实应用越来越感兴趣，特别是在聚变能源方面。我将在约克进行的项目题为“实验室中与天体物理相关的 QED 等离子体”，由 Kate Lancaster 博士和 Chris Ridgers 博士监督。该项目的重点是使用新型多 PW 激光器创建量子电动力学 (QED) 等离子体。激光强度的增加将允许观察到新的光与物质的相互作用，主要考虑到电磁场太强以至于产生 QED 等离子体的情况。等离子体受超相对论等离子体过程控制，该过程完全改变等离子体的行为。我们从经典过程转向量子效应。该领域开展的实验工作很少，因此 QED 等离子体在实验上相对未经探索。虽然这种新机制的基本物理原理在实验室中几乎完全未被探索，但 X 射线对于压缩惯性约束核心等致密材料的射线照相非常有用，而离子可用于新型快速点火聚变方案。该项目将结合实验室和实验工作以及模拟来探索这种新的等离子体状态。
