场助双折射康普顿散射
Field-assisted birefringent Compton scattering
摘要：
受亥姆霍兹国际极端场光束线（HIBEF）等实验倡议的启发，我们研究了强外场中电子对x射线的康普顿散射（例如，强光学激光器）并特别强调偏振改变（即，双折射）对振幅水平的贡献。除了作为计划中的真空双折射实验的潜在背景过程外，这种效应还可用于诊断目的。由于来自自由电子的双折射信号（即，没有外部场）在前向方向上消失，双折射和法向（偏振守恒）贡献的比率产生关于相互作用点处的场强的信息。
英文摘要：
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.
