摘要

偏振法是一种高灵敏度的方法,可以量化光穿过物质时偏振态的变化,因此在材料科学中得到广泛应用。同步加速器和x射线自由电子激光(XFEL)光源的发展导致了x射线偏振器的重大发展,为偏振学在研究光源和光束线参数以及样品特性方面的新应用开辟了前景。迄今为止,x射线偏振测量显示偏振纯度小于$1.4\乘以{10}^{-11}$,从而能够从超快现象中检测到非常小的信号。一个突出的应用是检测真空双折射。真空双折射在量子电动力学中得到了预测,并有望通过将XFEL与petawatt级光学激光器相结合来探测。我们回顾了光源和光学元件对x射线偏振仪的一般影响,以及真空双折射检测所需的质量。

X-ray polarimetry and its application to strong-field quantum electrodynamics
Abstract Polarimetry is a highly sensitive method to quantify changes of the polarization state of light when passing through matter and is therefore widely applied in material science. The progress of synchrotron and X-ray free electron laser (XFEL) sources has led to significant developments of X-ray polarizers, opening perspectives for new applications of polarimetry to study source and beamline parameters as well as sample characteristics. X-ray polarimetry has shown to date a polarization purity of less than $1.4\times {10}^{-11}$ , enabling the detection of very small signals from ultrafast phenomena. A prominent application is the detection of vacuum birefringence. Vacuum birefringence is predicted in quantum electrodynamics and is expected to be probed by combining an XFEL with a petawatt-class optical laser. We review how source and optical elements affect X-ray polarimeters in general and which qualities are required for the detection of vacuum birefringence.
