SOHO上的CEIAS实验旨在测量低速和高速太阳风、过热离子和低能耀斑粒子的质量、离子电荷和能量。通过对太阳大气中离子的元素丰度和同位素丰度、离子电荷状态和速度分布的分析，重点研究了太阳色球、过渡带和日冕在不同时间和空间尺度上的等离子体过程。Celias包括3个基于飞行时间技术的质量和电荷识别传感器：用于太阳风的元素、电荷和速度分布的CTOF，用于太阳风的元素和同位素组成的MTOF，以及用于过热离子的质量、电荷和能量分布的STOF。该仪器将提供详细的太阳风和加速粒子的现场诊断，这将补充SOHO上太阳大气的光学和光谱研究。Celias还包含一个太阳极端紫外线监测器，扫描电子显微镜，它在17-70 nm的宽带内连续测量EUV通量，并在30.4 nm He II线周围的一个窄带。
The CELIAS experiment on SOHO is designed to measure the mass, ionic charge and energy of the low and high speed solar wind, of suprathermal ions, and of low energy flare particles. Through analysis of the elemental and isotopic abundances, the ionic charge state, and the velocity distributions of ions originating in the solar atmosphere, the investigation focuses on the plasma processes on various temporal and spatial scales in the solar chromosphere, transition zone, and corona. CELIAS includes 3 mass- and charge-discriminating sensors based on the time-of-flight technique: CTOF for the elemental, charge and velocity distribution of the solar wind, MTOF for the elemental and isotopic composition of the solar wind, and STOF for the mass, charge and energy distribution of suprathermal ions. The instrument will provide detailed in situ diagnostics of the solar wind and of accelerated particles, which will complement the optical and spectroscopic investigations of the solar atmosphere on SOHO. CELIAS also contains a Solar Extreme Ultraviolet Monitor, SEM, which continously measures the EUV flux in a wide band of 17 – 70 nm, and a narrow band around the 30.4 nm He II line.
