设计并制作了一种由不同宽度的棱镜组成的x射线聚焦棱镜阵列折射透镜。为了稳定整个结构，降低制作难度，在齿状节段的两行之间引入了桥接。从理论上研究了桥梁对聚焦的影响，它会使聚焦的宽度变宽。此外，利用x射线光刻技术在同一衬底上制备了两个带桥和不带桥的50 keV x射线prl，并在上海同步辐射设施（SSRF）的BL13W1光束线上进行了测试。设计了宽度为5 μ m的桥，有桥的PRL样品的形貌优于无桥的PRL样品。在线聚焦测试结果表明，带桥和不带桥的样品的焦线宽度均为4。20 μ m和6。这表明用这种方法制作PRL是必须的。
A kind of prism-array refractive lens (PRL) for X-ray focusing composed of different prisms with the same width is designed and fabricated. In order to stabilize the whole structure and reduce the fabrication difficulty, bridges are introduced between the opposite two lines of tooth-like segments. The influence of the bridges on the focusing is investigated in theory, which will broaden the width of the focus. Furthermore, two PRLs with and without bridges for 50 keV X-rays are fabricated on the same substrate by X-ray lithography and are tested at BL13W1 beamline in Shanghai Synchrotron Radiation Facilities (SSRF). The bridges are designed a width of 5 μ m and the PRL sample with bridges has the better morphology than the one without bridges after fabrication. The on-line focusing test results show that the focal line width of the samples with and without bridges are 4. 20 μ m and 6. 34 μ m respectively, which implies that the bridges are necessary for the PRL with this fabrication method.
