论文摘要
超级电子电子束束脉冲散射实验是研究QED和可能在很大程度上未探索的强场状态下新物理学的可能特征的主力。但是，射击到射击的电子束和激光脉冲参数的波动使得很难辨别相互作用的动力学。因此，对实验结果进行基准测试的理论预测的可能性受到严格限制。在这里，我们表明量子排放事件的随机性质为电子束激光脉冲相互作用的射击诊断提供了独特的途径，因此为准确测量强场QED效应铺平了道路。
Ultrarelativistic electron beam-laser pulse scattering experiments are the workhorse for the investigation of QED and of possible signatures of new physics in the still largely unexplored strong-field regime. However, shot-to-shot fluctuations both of the electron beam and of the laser pulse parameters render it difficult to discern the dynamics of the interaction. Consequently, the possibility of benchmarking theoretical predictions against experimental results, which is essential for validating theoretical models, is severely limited. Here we show that the stochastic nature of quantum emission events provides a unique route to the on-shot diagnostic of the electron beam-laser pulse interaction, therefore paving the way for accurate measurements of strong-field QED effects.
