‘Space’ charging of insulators

Abstract

THE charging of satellite surfaces by space radiation often results in electrical discharges. These can interfere seriously with electrical systems on board1. The surface potentials may vary according to the differing charging properties of dissimilar materials, local changes in capacitance or differences in the radiation environment. Investigations of radiation-induced electron emission have been directed predominantly at metallic or semiconducting materials, and there is a paucity of data on the charging of dielectrics. The work reported here considers photon-induced charging. Electron-induced charging is considered in ref. 2.
