摘要
高能X射线组合透镜是一种基于折射效应的新型X射线光学元件。报道了这种新型X射线光学元件聚焦性能 的最新实验结果。设计的高能X射线组合透镜为聚甲基丙烯酸甲酯(PMMA)材料，包括40个相同的、顺序排布的平凹折射单元，折射单元的球面半径为200 μm，组合透镜的几何口径约为500 μm，长度约为8 mm，焦距约为1.3 m。简要描述了PMMA材料X射线组合透镜的制作技术和制作过程。并给出了X射线组合透镜聚焦性能测试实验系统和实验条件。最后给出8 keV单色X射线辐射下，PMMA材料X射线组合透镜的聚焦性能的测试结果，对实际测试结果进行了分析和讨论，得出结论，焦距等参量与理论计算结果基本吻合。
Abstract
The compound high-energy X-ray lens is a kind of novel refractive X-ray optical device. The latest experimental results of the focusing perfermance of the compound high-energy X-ray lens is designed with PMMA with the parameters of 40 plano-concave elementary lenses positioned in line with axial symmetry, 200 μm radius of the concave surface, 0.15 nm working wavelength, 0.5 mm geometrical aperture and 8 mm length of the compound lens and 1.3 m focus length, are briefly introduced. Then the experimental setup for the focusing performance is described, and the focusing performance of the PMMA compound high-energy X-ray lens is tested under the inradiation of the 8 keV monochromatic X-ray. The experimental results are in general coincident with the calculated results.
