Abstract

When charged particles impinged on the materials secondary electrons are excited, and the surfaces of insulators will be charged as a result. For spacecraft flying in space especially in the geosynchronous (GEO) environment, surface charging will be serious unless electrostatic-protected. Theory of surface charging has revealed the relationship between the secondary electron emission and surface potential, this article analyzed the surface potential of different materials by SPIS, and researched on the influence of secondary electron emission on surface charging based on the tested secondary electron yields of typical spacecraft surface materials, which can be referred for evaluating the level of spacecraft surface charging.
