Xeus使命旨在探索宇宙中高红移物体的X射线发射，使命的成功关键取决于在适合科学观测的轨道上部署一个10平方米级望远镜系统。对于这样一个大型设施来说，最小化望远镜的质量和体积变得至关重要。我们描述了新的重量轻的光学器件的发展，使每单位面积的质量减少超过一个数量级，与传统的复制光学技术相比。有了如此大的收集面积，图像混淆限制也成为一个科学的驱动因素，要求弧秒级分辨率。我们描述的测量表明，分辨率的提高，提供了非常高的信心，这些要求可以得到满足。简要介绍了该使命的一些实施细节。
The Xeus mission is designed to explore the X-ray emission from objects in the Universe at high redshifts, and the success of the mission depends critically on the deployment of a 10 square metre class telescope system in a suitable orbit for science observations. The minimisation of the telescope mass and volume becomes of critical importance for such a large facility. We describe developments of novel light weight optics that enable a reduction in mass per unit area of more than an order of magnitude, compared with traditional replication optics technology. With such a large collection area, image confusion limits become a scientific driver as well, demanding arcsecond class resolution. We describe measurements that demonstrate the improvement in resolution that gives very high confidence that these requirements can be met. Some implementation details of the mission are briefly mentioned.
