SRG上的eROSITA：一项X射线全天巡天任务
eROSITA on SRG: a X-ray all-sky survey mission
摘要：
eROSITA（带有成像望远镜阵列的扩展伦琴巡天）是定于2012年晚些时候发射的俄罗斯光谱伦琴伽马（SRG）飞行任务的核心仪器。eROSITA由德国航天局DLR和Max-Planck-Society完全批准和资助。设计驱动科学是探测5 - 10万个红移z ~ 1.3的星系团，以研究宇宙中的大尺度结构和检验宇宙学模型，特别是暗能量。这将通过为期四年的全天观测加上一个定点观测阶段来完成。eROSITA由7个Wolter-I望远镜模块组成，每个模块配备有54个外径为360 mm的Wolter-I外壳。这将提供约1500 cm 2的1.5 keV有效面积和15”的轴上PSF HEW，这将提供25”-30”的有效角分辨率。在每个反射镜模块的焦点上，一个快速帧存储pn-CCD将为约0.83 deg^2的有效FOV提供直径为1 deg^2的视场。在编写本报告时，仪器开发目前处于C/D阶段。
英文摘要：
eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the core instrument on the Russian Spektrum-Roentgen-Gamma (SRG) mission which is scheduled for launch in late 2012. eROSITA is fully approved and funded by the German Space Agency DLR and the Max-Planck-Society. The design driving science is the detection of 50 - 100 thousands Clusters of Galaxies up to redshift z ~ 1.3 in order to study the large scale structure in the Universe and test cosmological models, especially Dark Energy. This will be accomplished by an all-sky survey lasting for four years plus a phase of pointed observations. eROSITA consists of seven Wolter-I telescope modules, each equipped with 54 Wolter-I shells having an outer diameter of 360 mm. This would provide and effective area at 1.5 keV of ~ 1500 cm2 and an on axis PSF HEW of 15" which would provide an effective angular resolution of 25"-30". In the focus of each mirror module, a fast frame-store pn-CCD will provide a field of view of 1 deg in diameter for an active FOV of ~ 0.83 deg^2. At the time of writing the instrument development is currently in phase C/D.
