摘要:

DIOS(弥散星系间氧气探测器)是一颗小型卫星,计划于2020年左右由JAXA的Epanimus火箭发射。它的主要目的是寻找温暖的热星系际介质与高分辨率X射线光谱的红移发射线从OVII和OVIII离子。TES微量热计的高能量分辨率与非常宽的视场(30- 50弧分直径)相结合,将使我们能够在从地球磁层到星系团的非维里化区域的广泛空间尺度上观察宇宙等离子体的气体动力学。介绍了航天器的机械设计、热设计和TES量热系统的研制。我们还考虑修改有效载荷设计,以优化小型飞行任务边界条件所允许的科学能力。

英文摘要:

DIOS (Diffuse Intergalactic Oxygen Surveyor) is a small satellite aiming for a launch around 2020 with JAXA's Epsilon rocket. Its main aim is a search for warm-hot intergalactic medium with high-resolution X-ray spectroscopy of redshifted emission lines from OVII and OVIII ions. The superior energy resolution of TES microcalorimeters combined with a very wide field of view (30--50 arcmin diameter) will enable us to look into gas dynamics of cosmic plasmas in a wide range of spatial scales from Earth's magnetosphere to unvirialized regions of clusters of galaxies. Mechanical and thermal design of the spacecraft and development of the TES calorimeter system are described. We also consider revising the payload design to optimize the scientific capability allowed by the boundary conditions of the small mission.
