结合Fensnel反射系数公式与Nevot-Croce模型,设计出了可以用于同步辐射单色器的W/B4C周期多层膜,并对其光学性能(反射率)做了模拟计算。采用高真空磁控溅射技术,实现不同周期的W/B4C周期多层膜的制备。利用英国BEDE公司出产的D1高分辨X射线衍射仪,完成W/B4C周期多层膜周期结构的测量。在北京同步辐射荧光束线(4W1B)上,利用W/B4C多层膜获取准单色光,实现材料的荧光分析实验。实验结果证明,W/B4C多层膜对同步辐射白光起到了单色的作用,可以得到高强度的准单色同步辐射X射线。
Combining the Fensnel reflection coefficient formula and the Nevot-Croce model, W / B4C multi-layer films designed for synchrotron monochromator were designed and their optical properties (reflectance) were simulated. Using high vacuum magnetron sputtering technology to achieve different periods of W / B4C cycle multilayer film preparation. Using the D1 high resolution X-ray diffractometer produced by BEDE in the United Kingdom, the periodic structure of the W / B4C multilayer was measured. In Beijing synchrotron radiation fluorescence beam line (4W1B), using W / B4C multi-layer film to obtain quasi-monochromatic light, to achieve the material fluorescence analysis experiments. The experimental results show that the W / B4C multilayers have a monochromatic effect on the synchrotron radiation white light, and high intensity quasi monochromatic synchrotron radiation X-rays can be obtained.
