金刚石具有独特的性质，使其成为同步加速器仪器的理想材料。由金刚石制成的 X 射线光学器件几乎是透明的，具有强度，并且热膨胀非常低；因此，它们将能够承受第四代光源产生的强大光束，而不会影响亮度。出于这个原因，几个小组正在尝试制造由金刚石制成的折射透镜和波带片。光刻以及一般的微加工技术是同步加速器聚焦光学创新的终极工具。我们建议将现代硅微技术与先进的沉积方法相结合，制造用于第三代和第四代同步加速器源的纳米晶金刚石透镜。这里描述了制造方法并说明了微聚焦同步加速器测试。 (c) 2010 年美国物理研究所。 [号码：10.1063/1.3517060]
Diamond has unique properties which make it the ideal material for use in synchrotron instrumentation. X-ray optics made of diamond are almost transparent, they possess strength, and are subject to very low thermal expansion; therefore they will be able to withstand the powerful beams generated by fourth-generation light sources without compromising brilliance. For this reason, several groups are attempting fabrication of refractive lenses and zone plates made of diamond. Lithography and, in general, microfabrication technology, are the ultimate tools for the innovation of synchrotron focusing optics. We propose to combine modern silicon microtechnology with advanced deposition methods to fabricate nanocrystalline-diamond lenses for third-and fourth-generation synchrotron sources. The fabrication method is described here and microfocusing synchrotron tests are illustrated. (c) 2010 American Institute of Physics. [doi: 10.1063/1.3517060]
