项目摘要

The present proposal is intended to support the participation of Dr. Gianluca Sarri and his PhD student, Mr. Niall Cavanagh, of The Queen's University of Belfast to the experimental campaign E-320 at the FACET-II beamline of the Stanford Linear Accelerator (SLAC). The investigator of this proposal is a central member of an international collaboration of world-leading Universities and research institutes, including Princeton, Stanford, Ecole Polytechnique, the Max-Planck institute for Nuclear Physics, and UCLA that recently was awarded, in an extremely competitive environment, beam time at FACET-II for a series of ground-breaking experiments on Strong-Field Quantum ElectroDynamics (SFQED). In a nutshell, the experiments aim at studying the dynamics of the 13 GeV electron beam provided by the FACET-II accelerator as it propagates through the focus of a 20 TW laser system, already installed and operational. Peak intensities exceeding 1x1020 Wcm^-2 can be realistically achieved, allowing to reach a peak electric field, in the rest frame of the electrons, of the order of 70% of the Schwinger field, or critical field of QED. This value significantly exceeds what previously obtained at SLAC in the late 90s and, more recently, by the PI and collaborators using the Gemini laser at the Central Laser Facility in the UK. We plan to further advance previous work by performing precision measurements and collecting extensive data sets to provide sufficient statistics to study in detail iconic phenomena in SFQED, such as quantum radiation reaction, strongly non-linear Compton scattering, and pair production. The collected data will shed light at the current intensity frontier of high-power lasers, allowing one not only to test numerical and analytical models currently used in this physical regime, but also to optimise experimental techniques for the operation of the next generation of ultra-intense laser facilities.

本提案旨在支持贝尔法斯特女王大学的Gianluca Sarri博士及其博士生Niall Cavanagh先生参与斯坦福大学直线加速器FACET-II光束线的实验活动E-320。该提案的研究者是世界领先的大学和研究机构的国际合作的核心成员，包括普林斯顿大学，斯坦福大学，Ecole Polytechnique，Max-Planck核物理研究所和UCLA，最近在竞争激烈的环境中获得了FACET-II的束流时间，用于强场量子电动力学（SFQED）的一系列突破性实验。简而言之，这些实验旨在研究FACET-II加速器提供的13 GeV电子束在通过已经安装和运行的20 TW激光系统的焦点传播时的动力学。实际上可以达到超过1 × 1020 Wcm^-2的峰值强度，在电子的静止坐标系中，峰值电场约为Schwinger场或QED临界场的70%。该数值大大超过了90年代后期SLAC获得的数值，以及最近PI和合作者在英国中央激光设施使用Gemini激光获得的数值。我们计划通过进行精确测量和收集大量数据集来进一步推进以前的工作，以提供足够的统计数据来详细研究SFQED中的标志性现象，例如量子辐射反应，强非线性康普顿散射和对产生。收集到的数据将揭示高功率激光器当前的强度前沿，不仅可以测试目前在这一物理机制中使用的数值和分析模型，还可以优化下一代超强激光设施的实验技术。
