论文摘要
有效的收集区域，角度分辨率，视野和能量响应是X射线望远镜的基本属性。目前，最先进的望远镜的性能受到沃尔特光学元件的限制，尤其是对于硬X射线。在本文中，我们报告了一种新方法的发展 - 堆叠的棱镜镜，它是轻巧的，模块化的，并且具有显着改善有效区域的潜力，同时保持高角度分辨率。所提出的光学元件是通过堆叠嵌入式棱镜圈的光盘构建的，该光盘由弹药师通过聚焦紫外线光刻创建。我们使用在同步加速器辐射设施上制造和表征的原型镜头展示了SPL方法。概述了潜在的卫星X射线望远镜的设计，并将性能与当代任务进行了比较。
Effective collecting area, angular resolution, field of view and energy response are fundamental attributes of X-ray telescopes. The performance of state-of-the-art telescopes is currently restricted by Wolter optics, especially for hard X-rays. In this paper, we report the development of a new approach - the Stacked Prism Lens, which is lightweight, modular and has the potential for a significant improvement in effective area, while retaining high angular resolution. The proposed optics is built by stacking discs embedded with prismatic rings, created with photoresist by focused UV lithography. We demonstrate the SPL approach using a prototype lens which was manufactured and characterized at a synchrotron radiation facility. The design of a potential satellite-borne X-ray telescope is outlined and the performance is compared to contemporary missions.
