【摘要】 介绍了整体X光透镜的物理性能。使用X光透镜进行了生物大分子晶体衍射实验,结果表明:在相同X光源功率条件下,衍射强度提高了近7倍,大大缩短了测试时间,分辨能力改善0.2×10^-10～0.6×10^-10m,信噪比也有改善。在粉末衍射仪上,进行了Si（100）衬底上金薄膜的衍射实验,结果表明:在相同X光源功率条件下,使用X光透镜后的衍射强度提高了近2倍,同时改善了衍射仪的角分辨率。更多还原

【Abstract】 The basic physical properties for monolithic X-ray lens are introduced. The X-ray diffraction for macromolecular crystallography using monolithic X-ray lens were investigated. The experimental results show that in the same X-ray source power the diffracted intensity in the condition with X-ray lens was increased about7 times, and the resolution was improved by 0.2X10-10 -0.6X10-10m. The signal tonoise ratio was also improved, and the time of measurement was reduced. The X-ray diffraction of Au thin films on the Si (100) single crystal substrates were investigated in a X-ray powder diffractometer. The experimental results show that in the same X-ray source power the diffracted intensity in the condition with X-ray lens was increased about 2 times, and the angular resolution of the diffractometer was enhanced.更多还原
