X射线全天监视器XASM载荷及其科学性能模拟简介

摘要

在国内外X射线天文观测的需求下,提出了利用空间站平台开展X射线巡天观测的项目X射线全天监视器(XASM),简单介绍了XASM的科学目标,详细描述了其基于MPO光学技术的龙虾眼光学系统和XASM科学性能模拟方面的工作,包括PSF,有效面积和天空成像等.%Based on the analysis of X-ray astronomical observations, the project of X-ray All Sky Monitor ( XASM) was proposed for the space station. In this paper, the scientific objectives were concisely presented, and its MPO lobster-eye optics was described in detail. In addition, the scien-tific capabilities of XASM were simulated including the PSF, the effective area and the image of dif-ferent x-ray sources.
