论文摘要
由实验性举措（例如Helmholtz国际极端田地（Hibef））的动机，我们研究了X射线在强大外部田间（例如，强烈的光学激光器）中X射线的康普顿散射，并特别强调了偏振变化（即，双回合）对振幅级别的贡献。除了是计划的真空双折射实验的潜在背景过程外，此效果还可以用于诊断目的。由于来自游离电子的双重信号（即没有外部场）在正方向上消失，因此双重之比和正常（极化保存）的贡献产生了有关相互作用点处的磁场强度的信息。
Motivated by experimental initiatives such as the Helmholtz International Beamline for Extreme Fields (HIBEF), we study Compton scattering of x-rays at electrons in a strong external field (e.g., a strong optical laser) with special emphasis on the polarization-changing (i.e., birefringent) contribution on the amplitude level. Apart from being a potential background process for the planned vacuum birefringence experiments, this effect could be used for diagnostic purposes. Since the birefringent signal from free electrons (i.e., without the external field) vanishes in forward direction, the ratio of the birefringent and the normal (polarization conserving) contribution yields information about the field strength at the interaction point.
