Quantum Electrodynamics (QED), the relativistic quantum theory how light interacts with matter, is currently the most precise theory in science. The precision of this theory is based on perturbation theory and at higher laser light intensities non-linear phenomena become significant. These non-linear phenomena can be compared to theoretical QED, and this is the primary aim of the LUXE experiment. LUXE will collide electrons (or secondary photons from electrons) with a high-power laser, this will allow a detailed probe of non-linear QED. Approximately half of the required experiment is the electron accelerator, which is the European Free Electron Laser (XFEL.EU) and numerous accelerator physics activities are required for the success of LUXE. These activities are numerous and will contribute to the PhD thesis, these include (not exclusively) i. simulation of the accelerator complex, beam instrumentation and beam backgroundsii. integration of beam instrumentation in the measurement and simulation of LUXEiii. design of the electron beam dumpiv. design of the inverse Compton scattering chamberv. analysis and simulation of the collision datavi. investigation of coherent bremsstrahlung as a photon sourceThe core of the PhD thesis will be a range of experiments and simulations that are related to core physics mission of LUXE. The thesis will end around the start of data taking for LUXE, and the project will probably conclude with some (limited) experimental commissioning data. The student will become a member of the LUXE collaboration, an international group of particle physicists. The student might have to undertake common tasks for the collaboration. The collaboration will publish multiple outputs during the PhD including a technical design report, physics impact papers, and high impact journal publications. It is expected that the student will be a co-author on these publications. The student will also join dedicated working groups for specific topics related to their PhD research. The LUXE experiment is based at the German national laboratory for high energy physics (DESY), and they might be expected to visit frequently or have a longer stay, compatible with the needs of the experiment, their personal training and commitments.

量子电动力学（QED），光与物质相互作用的相对论量子理论，是目前科学中最精确的理论。该理论的精确性基于微扰理论，并且在较高的激光强度下，非线性现象变得显着。这些非线性现象可以与理论QED相比较，这是LUXE实验的主要目的。LUXE将用高功率激光碰撞电子（或电子的次级光子），这将允许对非线性QED进行详细的探测。所需实验的大约一半是电子加速器，即欧洲自由电子激光器（XFEL.EU），LUXE的成功需要许多加速器物理活动。这些活动是众多的，将有助于博士论文，这些包括（不限于）i。加速器综合体、束流仪表和束流背景的模拟。在LUXEiii的测量和模拟中集成束流仪器。电子束流反推设计逆康普顿散射室的设计。碰撞数据的分析与仿真。作为光子源的相干韧致辐射的研究本博士论文的核心将是一系列与LUXE核心物理使命相关的实验和模拟。论文将围绕LUXE的数据采集开始结束，该项目可能会以一些（有限的）实验调试数据结束。学生将成为LUXE合作的成员，这是一个国际粒子物理学家组织。学生可能必须承担共同的任务进行合作。该合作将在博士期间发表多项成果，包括技术设计报告，物理影响论文和高影响力期刊出版物。预计学生将成为这些出版物的共同作者。学生还将加入专门的工作组，与他们的博士研究相关的特定主题。LUXE实验位于德国国家高能物理实验室（DESY），他们可能会经常访问或停留更长时间，以满足实验的需要，他们的个人培训和承诺。
