未来的X射线天文任务将需要解决许多重要的目标，例如研究星系团的动力学，确定大质量恒星爆炸中元素是如何产生的，以及揭示宇宙中大部分“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。为了实现这些目标，需要具有高分辨率和高通量的光谱仪来实现最低 X 射线能量（0.3-1.0 keV）。我们介绍了用于即将执行的任务的离面反射光栅技术开发的最新进展。离面光栅光谱仪由分辨率能够达到 3000 (λ/Δλ) 以上的光栅阵列组成。国际X射线天文台X射线光栅光谱仪的概念设计已经完成。然而最近，我们为 WHIMex 设计了一个光学模块组件，这是一个探索者任务概念，包含 Wolter 望远镜、转向平面和光栅阵列。本文将讨论这些设计以及未来离面阵列的应用。
Future X-ray astronomical missions will need to address a number of important 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. In order to achieve these goals, spectrometers capable of high resolution and high throughput are necessary for the lowest X-ray energies, 0.3-1.0 keV. We present recent progress in the development of off-plane reflection grating technology for use on upcoming missions. Off-plane grating spectrometers consist of an array of gratings capable of reaching resolutions above 3000 (λ/Δλ). Concept designs have been made for the International X-ray Observatory X-ray Grating Spectrometer. More recently however, we have designed an Optics Module Assembly for WHIMex, an Explorer mission concept that incorporates a Wolter telescope, steering flats, and an array of gratings. This paper will discuss these designs and the application of off-plane arrays for the future.
