基于Langmuir探针技术的空间等离子体探测方法

Space Plasma Detecting Method Based on the Langmuir Probe

阐述了Langmuir探针测量空间等离子体的基本原理和方法。分析了利用Langmuir探针在空间等离子体探测应用中航天器、空间环境对探针表面污染、探针自身和其他因素对测量的影响。介绍了一种基于探针与空间等离子体同电位的等离子体电位和密度的探测方法,并给出测量原理和探针结构。

The principle and method of space plasma detecting by Langmuir probe were descbied in this paper. The effects of spacecraft, probe surface contamination caused by space environment, probe itself and other factors on the space plasma detecting using Langrnuir probe were analyzed. A method to detect space plasma potential and electron density based on the equal potential of the probe and plasma was put forward, and the measurement mechanism and probe structure were also given.
