国际x射线天文台(IXO)是NASA、ESA和JAXA的合作项目。IXO的科学目标很大程度上基于获得高质量的x射线光谱。为了实现这一目标,科学有效载荷将在最低x射线能量(0.3 - 1.0 keV)下纳入一系列高分辨率、高通量光谱的光栅。光谱仪将解决一些重要的天体物理学目标,如研究星系团的动力学,确定元素是如何在大质量恒星爆炸中产生的,以及揭示宇宙中大多数“正常”物质,这些物质目前被认为隐藏在星系之间伸展的热气体细丝中。本文提出了一种成熟的离面x射线光栅光谱仪(OP-XGS)的设计概念。这种XGS概念在光学和机械设计方面取得了重大进展。我们在这里分析了基准OP-XGS设计如何满足XGS的IXO科学要求以及该设计的光学和机械细节。
The International X-ray Observatory (IXO) is a collaborative effort between NASA, ESA, and JAXA. The IXO science goals are heavily based on obtaining high quality X-ray spectra. In order to achieve this goal the science payload will incorporate an array of gratings for high resolution, high throughput spectroscopy at the lowest X-ray energies, 0.3 - 1.0 keV. The spectrometer will address a number of important astrophysical goals such as studying the dynamics of clusters of galaxies, determining how elements are created in the explosions of massive stars, and revealing most of the "normal" matter in the universe which is currently thought to be hidden in hot filaments of gas stretching between galaxies. We present here a mature design concept for an Off-Plane X-ray Grating Spectrometer (OP-XGS). This XGS concept has seen recent significant advancements in optical and mechanical design. We present here an analysis of how the baseline OP-XGS design fulfills the IXO science requirements for the XGS and the optical and mechanical details of this design.
