一种新的毛细管光学聚焦同步辐射X射线束的技术已被应用于在HASYLAB的DORIS储存环上进行的实验。这种新技术利用了X射线在小毛细管内的全反射特性，最近已被应用于产生X射线微束，使用传统的X射线管，其束尺寸可降至约10 μ m。实验结果表明，毛细管光学系统也可用于同步辐射光源产生亚微米X射线束。本文介绍了毛细管光学系统的结构和准直方法。讨论了同步辐射强通量对器件热负荷的影响。将讨论毛细管技术应用于同步辐射的未来前景。
A novel capillary optics technique for focusing synchrotron X-ray beams has been applied in an experiment performed at the DORIS storage ring at HASYLAB. This new technique, which utilizes the total reflection properties of X-rays inside small capillaries, has recently been applied to generate microbeams of X-rays, with a beam size down to about 10-mu-m using conventional X-ray tubes. The result from our recent experiment shows that capillary optics can also bc used to generate a submicron beam of X-rays from a synchrotron light source.A description of the capillary unit, and the alignment procedure is given. The influence of the thermal load on the device caused by the intense flux of synchrotron radiation will be discussed. Future perspectives of the capillary technique as applied to synchrotron radiation will be discussed.
