The multilayer Laue lens (MLL) is a novel diffraction optics which can realize nanometer focusing of hard X-rays with high efficiency. In this paper, a 7.9 μm-thick MLL with the outmost layer thickness of 15 nm is designed based on dynamical diffraction theory. The MLL is fabricated by first depositing the depth-graded multilayer using direct current (DC) magnetron sputtering technology. Then, the multilayer sample is sliced, and both cross-sections are thinned and polished to a depth of 35-41 μm. The focusing property of the MLL is measured at the Shanghai Synchrotron Facility (SSRF). One-dimensional (1D) focusing resolutions of 205 nm and 221 nm are obtained at E=14 keV and 18 keV, respectively. It demonstrates that the fabricated MLL can focus hard X-rays into nanometer scale.  相似文献

磁控溅射制备横向梯度分布的Mo/Si周期多层膜   总被引:1,自引:0,他引:1       下载免费PDF全文
 采用磁控溅射方法在Si基板上镀制了横向梯度分布的Mo/Si周期多层膜。以X射线掠入射反射测量了横向梯度多层膜的膜系结构,在基板65 mm长度范围内,多层膜周期从8.21 nm线性减小到6.57 nm,周期梯度为0.03 nm/mm。国家同步辐射实验室反射率计的反射率测试结果表明:该横向梯度分布周期多层膜上不同位置,能反射在13.3~15.9 nm波段范围内不同波长的极紫外光,反射率为60%~65%。  相似文献
