Thomson backscattering of intense laser pulses from relativistic electrons not only allows for the generation of bright x-ray pulses but also for the investigation of the complex particle dynamics at the interaction point. For this purpose a complete spectral characterization of a Thomson source powered by a compact linear electron accelerator is performed with unprecedented angular and energy resolution. A rigorous statistical analysis comparing experimental data to 3D simulations enables, e.g., the extraction of the angular distribution of electrons with 1.5% accuracy and, in total, provides predictive capability for the future high brightness hard x-ray source PHOENIX (photon electron collider for narrow bandwidth intense x rays) and potential gamma-ray sources.
强激光脉冲从相对论电子的汤姆逊背散射不仅可以产生亮的 X 射线脉冲，还可以研究相互作用点处复杂的粒子动力学。为此，采用前所未有的角分辨率和能量分辨率对紧凑型线性电子加速器驱动的汤姆逊源进行了完整的光谱特性描述。通过严格的统计分析，将实验数据与 3D 模拟进行比较，例如，可以以 1.5%的精度提取电子的角分布，并且总共为未来的高亮度硬 X 射线源 PHOENIX（窄带宽强 X 射线的光子电子对撞机）和潜在的伽马射线源提供了预测能力。
