Extreme Physics driven by High Intensity Laser Plasma

学生将有助于TeX-MeX项目的实验和数据分析方面，该项目旨在使用激光韦克菲尔德加速器研究极端条件。实验将使用激光韦克菲尔德加速器来产生可用于探测极端条件的高能电子束。学生的工作将主要贡献于以下工作包：WP 1：热致密物质这涉及到对加热到超过100 eV温度的固体密度或以上的物质的研究。实验将采取时间分辨X射线吸收光谱的形式，使用由激光韦克菲尔德加速产生的X射线来探测加热的样品（通过快速电子加热）。WP 2：温暖的致密物质这涉及对加热到大约110 eV温度的固体密度或以上的物质的研究。高分辨率X射线吸收光谱将被用来研究这种奇异状态的物质的行为。WP 3：极端光子密度。这涉及极端光子密度的研究：例如，在高密度X射线场或极高密度激光场中，可以产生电子正电子对。实验将在英国的CLF和其他国际激光设施进行，但可能包括密歇根大学的Hercules，LCLS的MEC和LBNL的BELLA设施。

The student will contribute to the experimental and data analysis aspects of the TeX-MeX project which aims to study extreme conditions using laser wakefield accelerators. Experiments will use laser wakefield accelerators to generate high energy electron beams that can be used to probe extreme conditions. The student's work will mostly contribute to the following work packages: WP1: Hot Dense matter This concerns the study of matter at or above solid density heated to temperatures in excess of 100 eV. Experiments will take the form of time resolved X-ray absorption spectroscopy using the X-rays produced by a laser wakefield acceleration to probe a heated sample (via fast electron heating).WP2: Warm Dense MatterThis concerns the study of matter at or above solid density heated to temperatures at temperatures around 1 10 eV. High resolution X-ray absorption spectroscopy will be employed to study the behaviour of this exotic state of matter.WP3: Extreme Photon densities. This concerns the study of extreme photon densities: for example, in high density X-ray fields, or extremely high-density laser fields electron positron pairs can be produced. Experiments will take place at the CLF in the UK and other international laser facilities, to be determined, but likely to include Hercules at the University of Michigan, the MEC at LCLS and the BELLA facility at LBNL.
