论文摘要
在最近的实验计划中，例如在欧洲X射线无电子激光器（XFEL）的Helmholtz国际极端田地（HIBEF）中，我们计算了X射线在两个光学（或近距离）激光器的联合场上的X射线散射。为了促进对量子真空衍射和双折射的实验检测，特别强调了最初和最终X射线光子之间差异之间的差异。除了它们的极化外，这些信号和背景光子在传播方向（对应于MRAD方向上的散射角度）以及可能的能量可能会有所不同。
Motivated by recent experimental initiatives, such as at the Helmholtz International Beamline for Extreme Fields (HIBEF) at the European X-ray Free Electron Laser (XFEL), we calculate the birefringent scattering of x-rays at the combined field of two optical (or near-optical) lasers and compare various scenarios. In order to facilitate an experimental detection of quantum vacuum diffraction and birefringence, special emphasis is placed on scenarios where the difference between the initial and final x-ray photons is maximized. Apart from their polarization, these signal and background photons may differ in propagation direction (corresponding to scattering angles in the mrad regime) and possibly energy.
