抽象的。地球的环电流和它如何响应不同的行星际条件的描述和帐户的生产提供的高能中性原子（ENA）在地冠。此外，还指出了通过分析磁暴/亚暴期间记录的ENA图像，在全球范围内远程监测磁层等离子体群时空演变的潜力。以下是对中国TC-2使命（测量范围45->158千电子伏）上的高能中子原子探测器单元NUADU的技术说明，以及NUADU在独立模式和多点成像方面的科学目标说明。NUADU在2004年9月中等磁暴时TC-2的南极通道期间记录的低空ENA排放，以及2004年11月在一次大磁暴期间记录的亮环电流排放，在各种伴随的陆地扰动的背景下进行了介绍和讨论。此外，2004年11月的环电流同时成像的TC-2/NUADU和IMAGE/ HENA（观察，分别从北方和南半球）的ENA观测进行了比较。
Abstract. The Earth’s ring current and how it responds to varying interplanetary conditions is described and an account provided of the production of Energetic Neutral Atoms (ENAs) in the geo-corona. Also, the potential to remotely monitor, on a global scale, the temporal and spatial evolution of magnetospheric plasma populations through analysing ENA images recorded during magnetic storms/substorms is indicated. A technical account of the Energetic NeUtral Atom Detector Unit NUADU aboard China’s TC-2 mission (measurement range 45–>158 keV) follows, together with an account of the scientific objectives of NUADU, both in stand-alone mode and in the context of multi-point imaging. Low altitude ENA emissions recorded by NUADU during south polar passages of TC-2 at the time of a moderate magnetic storm in September 2004, as well as bright ring current emissions recorded in November 2004 during a major geomagnetic storm, are presented and discussed in the context of various, accompanying, terrestrial disturbances. Also, ENA observations of the November 2004 ring current imaged simultaneously by TC-2/NUADU and by IMAGE/ HENA (viewing, respectively, from the Northern and Southern Hemispheres), are compared.
