Here, we report on the conceptual design, the hardware realization, and the first experimental results of a novel and compact x-ray polarimeter capable of a single-pulse linear polarization angle detection in the extreme ultraviolet photon energy range. The polarimeter is tested by performing time resolved pump–probe experiments on a Ni80Fe20 Permalloy film at the M2,3 Ni edge at an externally seeded free-electron laser source. Comparison with similar experiments reported in the literature shows the advantages of our approach also in view of future experiments.

一种用于磁动力学研究的新型自由电子激光单脉冲沃拉斯顿旋光仪

在这里,我们报告了一种能够在极紫外光子能量范围内进行单脉冲线性偏振角检测的新型紧凑型 X 射线偏振计的概念设计、硬件实现和首次实验结果。旋光仪是通过在外部种子自由电子激光源的 M 2,3 Ni 边缘的 Ni 80 Fe 20坡莫合金薄膜上进行时间分辨泵浦探针实验来测试的。与文献中报道的类似实验的比较显示了我们方法的优势,也考虑到了未来的实验。
