摘要

高亮度x射线自由电子激光器(XFELs)的发展,如硬x射线自播种自由电子激光器和XFEL振荡器(XFELOs),由于其强烈的非均匀热负载,给晶体单色仪带来了严峻的挑战。空间温度梯度引起的畸变会严重影响晶体的光学性能。因此,本文提出了一个模型来估计非均匀热畸变晶体的性能。该模型不仅考虑了热应变、斜率误差和入射角偏差,还考虑了与温度相关的Debye-Waller因子和电敏感性等因素。我们的研究表明,Debye-Waller因子降低了摇摆曲线的高度和带宽,而电磁化率的影响很小。该模型可以描述非均匀热负载晶体的反射率和透射率曲线的畸变,可用于晶体单色仪、晶体分配器、晶体压缩器和XFELOs的设计。

X-ray diffraction performance of thermally distorted crystals
Abstract The development of high-brightness X-ray free electron lasers (XFELs), such as hard X-ray self-seeding free electron lasers and XFEL oscillators (XFELOs), brings a severe challenge to the crystal monochromator due to a strong non-uniform thermal load. The distortion caused by spatial temperature gradients can severely affect the optical performance of crystals. Therefore, this paper presents a model to estimate the performance of non-uniform thermally distorted crystals. The model not only takes into account thermal strain, slope error and incident angle deviation, but also considers temperature-dependent factors such as the Debye–Waller factor and electric susceptibility. Our investigation indicates that the Debye–Waller factor reduces the height and bandwidth of rocking curves, and the impact of the electric susceptibility is tiny. The proposed model can describe the distortion of the reflectivity and transmissivity curves of non-uniform thermally loaded crystals and can be applied in the design of crystal monochromators, crystal splitters, crystal compressors and XFELOs.
