We propose a method to use traveling-wave Thomson scattering for spatiotemporally-resolved electron spectroscopy. This can enable ultrafast time-resolved measurements of the dynamics of relativistic electrons in the presence of extremely intense light fields, either in vacuum or in plasma, such as in laser wakefield accelerators. We demonstrate, with test-particle simulation and analysis, the capability of this technique for measurements of various high field phenomena: radiation reaction of electrons due to scattering, dephasing of a laser wakefield accelerator, and acceleration of electrons in multiple buckets by a laser wakefield.

电子束光谱的行波汤姆森散射

我们提出了一种使用行波汤姆森散射进行时空分辨电子光谱的方法。这可以在真空或等离子体(例如激光尾波加速器)中存在极强光场的情况下,对相对论电子的动力学进行超快速的时间分辨测量。我们通过测试粒子模拟和分析证明了该技术用于测量各种高场现象的能力:由于散射而产生的电子辐射反应,激光尾波场加速器的相移以及激光尾波场在多个桶中电子的加速。
