摘要

我们提出了一种利用粉红色自放大自发发射（SASE） x射线自由电子激光束的三维互向空间映射（RSM）方法。SASE光束中每个特定脉冲的能量可以用抽运本身激发的样品的衍射模式作为光谱参考来确定。利用该方法成功地重建了一个厚度与粉色光束的能量带宽相对应的RSM薄板。在泵浦探针x射线衍射测量过程中，通过摇动样品的几个步骤，我们获得了覆盖NiO薄膜中扩散散射和布拉格棒的三维RSM。

Pump-probe reciprocal-space mapping using energy-resolved XFEL pink beam pulses.

We present a 3D reciprocal-space mapping (RSM) method using a pink self-amplified spontaneous emission (SASE) X-ray free-electron laser beam. The energy of each specific pulse in a SASE beam can be determined using the diffraction pattern of a specimen excited by pumping itself as a spectroscopic reference. A thin slab of RSM, whose thickness corresponds to the energy bandwidth of the pink beam, is successfully reconstructed using the proposed method. By rocking a sample in a few steps, we obtained a 3D RSM covering both the diffuse scattering and the Bragg rod in NiO thin films during a pump-probe X-ray diffraction measurement.
