多年来，沃尔特镜一直被用作X射线望远镜的成像元件。电铸过程中的复制误差是通过复制芯棒形状来制造Wolter反射镜的形状误差来源。我们一直在开发用于同步辐射X射线的X射线聚焦镜，以及高精度电铸工艺。在本文中，我们报告了先进的电铸工艺的FOXSI太阳观测项目沃尔特镜的制造应用。并对芯轴的加工精度进行了讨论。
For many years, Wolter mirrors have been used as imaging elements in X-ray telescopes. The shape error of Wolter mirrors fabricated by replicating the shape of a mandrel originates from the replication error in electroforming. We have been developing an X-ray focusing mirror for synchrotron radiation X-rays, as well as a high-precision electroforming process. In this paper, we report on the application of the advanced electroforming process to the fabrication of Wolter mirrors for the FOXSI Sun observation project. We also discuss the figuring accuracy of the mandrel.
