摘要

摘要介绍了在同步辐射源 "KISI-Kurchatov"（俄罗斯莫斯科）对 X 射线硅平面复合折射透镜的光学特性进行的实验研究。该设施首次展示了利用折射光学产生亚微米 X 射线光束的能力。使用刀刃技术确定了聚焦光束的参数。测得的最小横向焦斑尺寸为 460 ± 70 nm。此外，还研究了焦斑区域的光束空间结构。对透镜光学特性的理论估计和相应的计算机模拟结果与实验数据一致。

Submicron Focusing of X-rays by Silicon Planar Compound Refractive Lenses

The experimental study of optical properties of X-ray silicon planar compound refractive lenses at the synchrotron radiation source “KISI–Kurchatov” (Moscow, Russia) are presented. The capability to generate a submicron X-ray beam using refractive optics was demonstrated for the first time at this facility. The parameters of the focused beam were determined using the knife-edge technique. The measured minimum lateral focal spot size was 460 ± 70 nm. Additionally, the spatial structure of the beam in the focal spot area was examined. Theoretical estimates of the lenses optical properties and the corresponding computer simulation results are in agreement with the experimental data.
