这份概念设计报告描述了LUSE(激光和XFEL实验)，这是一项旨在将欧洲XFEL的高质量和高能电子束与强大的激光相结合的实验活动，以探索以高能和高强度为特征的量子电动力学的未知领域。我们将通过分析强激光聚焦提供的极端环境中的高能电子-光子和光子-光子相互作用来达到这一迄今无法达到的量子物理学领域。物理背景及其相关性在科学案例中给出，这反过来又导致并证明了实验所有方面的后续计划：我们对实验参数的选择允许(I)在与电荷的耦合变得非微扰的情况下探测场强，以及(Ii)实现允许测量数据与计算进行详细比较的精度。此外，预测的高光子流将使人们能够在标准模型之外灵敏地寻找新的物理。实验的第一阶段将使用现有的40TW激光器，而第二阶段将使用升级后的350TW激光功率。所有关于实验装置性能的预期以及预期的物理结果都是基于贯穿始终的详细的数值模拟。
This Conceptual Design Report describes LUXE (Laser Und XFEL Experiment), an experimental campaign that aims to combine the high-quality and high-energy electron beam of the European XFEL with a powerful laser to explore the uncharted terrain of quantum electrodynamics characterised by both high energy and high intensity. We will reach this hitherto inaccessible regime of quantum physics by analysing high-energy electron-photon and photon-photon interactions in the extreme environment provided by an intense laser focus. The physics background and its relevance are presented in the science case which in turn leads to, and justifies, the ensuing plan for all aspects of the experiment: Our choice of experimental parameters allows (i) field strengths to be probed where the coupling to charges becomes non-perturbative and (ii) a precision to be achieved that permits a detailed comparison of the measured data with calculations. In addition, the high photon flux predicted will enable a sensitive search for new physics beyond the Standard Model. The initial phase of the experiment will employ an existing 40 TW laser, whereas the second phase will utilise an upgraded laser power of 350 TW. All expectations regarding the performance of the experimental set-up as well as the expected physics results are based on detailed numerical simulations throughout.
