Preparing for the Solar Orbiter Mission: Studies of the Links between the Sun and the Solar Wind Charged Particle Populations

UCL/MSSL既是提供太阳风分析仪(SWA)仪器套件的国际财团的首席研究员(PI)研究所，也是欧空局太阳轨道器任务的极端紫外光成像仪(EUI)的科学领导。这项任务可能会在2020年2月发射。SWA将对距离太阳不同距离的电子、质子、阿尔法粒子和重离子群进行采样，精度可达0.28 AU(即从太阳到地球距离的四分之一左右)。特别是，UCL/MSSL为SWA套件设计和建造了电子分析系统(EAS)。EUI由一套成像望远镜组成，用于观测太阳大气。EUI将使我们能够一方面确定日冕的全球结构，另一方面提供对动态太阳大气中精细尺度过程的关键了解。由EUI套件的全太阳成像仪(FSI)拍摄的图像将提供太阳表面和外冕之间不可或缺的联系，最终塑造将由太阳轨道器现场采样的行星际介质的特征。

UCL/MSSL is both the Principal Investigator (PI) Institute on an international consortium providing the Solar Wind Analyser suite (SWA) of instruments and co-PI Institute and science lead on the Extreme Ultraviolet Imager (EUI) for the ESA Solar Orbiter mission. The mission will likely be launched in Feb 2020. SWA will sample electron, proton, alpha particle and heavy ion populations at various distances down to 0.28 AU from the Sun (i.e. around a quarter the distance from the Sun to the Earth). In particular, UCL/MSSL has designed and built the electron analyser system (EAS) for the SWA suite. EUI consists of a suite of imaging telescopes to observe the solar atmosphere. EUI will allow us, on one hand, to determine the global structure of the solar corona and, on the other hand, to provide a crucial understanding of fine scale processes in the dynamic solar atmosphere. Images taken by the Full Sun Imager (FSI) of the EUI suite will offer the indispensable link between the solar surface and the outer corona, which ultimately shapes the characteristics of the interplanetary medium to be sampled in situ by Solar Orbiter.
