DIXE（Diffuse X-ray Explorer）是中国空间站（CSS）上的高分辨率X射线光谱巡天仪。DIXE将专注于研究银河系中的热重子。银河系的热重子，如X射线发射的银河系晕和eROSITA气泡，最好是在天空调查模式与大视场观察。DIXE将利用CSS的轨道运动来扫描大部分天空。基于过渡边缘传感器（TES）技术的超导微量热仪实现的高分辨率X射线光谱学将探测物理特性（例如，温度，密度，元素丰度，运动学）的银河系热重子。这将补充eROSITA使命获得的高分辨率成像数据。在这里，我们提出了初步设计的DIXE。有效载荷主要由探测器组件和低温冷却系统组成。检测器组件的关键部件是微量热计阵列和频域多路复用读出电子器件。为了给探测器组件提供工作温度，冷却系统由绝热退磁制冷机和机械制冷机系统组成。
DIffuse X-ray Explorer (DIXE) is a proposed high-resolution X-ray spectroscopic sky surveyor on the China Space Station (CSS). DIXE will focus on studying hot baryons in the Milky Way. Galactic hot baryons like the X-ray emitting Milky Way halo and eROSITA bubbles are best observed in the sky survey mode with a large field of view. DIXE will take advantage of the orbital motion of the CSS to scan a large fraction of the sky. High-resolution X-ray spectroscopy, enabled by superconducting microcalorimeters based on the transition-edge sensor (TES) technology, will probe the physical properties (e.g., temperature, density, elemental abundances, kinematics) of the Galactic hot baryons. This will complement the high-resolution imaging data obtained with the eROSITA mission. Here we present the preliminary design of DIXE. The payload consists mainly of a detector assembly and a cryogenic cooling system. The key components of the detector assembly are a microcalorimeter array and frequency-domain multiplexing readout electronics. To provide a working temperature for the detector assembly, the cooling system consists of an adiabatic demagnetization refrigerator and a mechanical cryocooler system.
