Abstract: In view of the fact that there are few researches on induced electrostatic discharge at home and abroad, in order to understand the basic characteristics of Electro Static Discharqi (ESD) induced by radiation field in natural environment and further analyze the characteristics of ESD induced by radiation field, an experimental system of ESD induced by atmosphere was established. In this paper, by means of theoretical analysis and experimental verification, the basic rules of needle-sphere electrode structure discharge induced by ESD radiation field are explored, and the basic rules of induced discharge are preliminarily obtained. The results show that the repetition frequency of the induced discharge increases with the increase of radiation field while controlling the external conditions; the repetition frequency of the induced discharge increases with the increase of voltage of high voltage source when controlling the radiation field intensity; and the unique threshold of induced discharge when controlling the external environment conditions can be determined. These experimental rules provide experimental methods and theoretical basis for studying the induced discharge characteristics under vacuum conditions, and are of great significance for the study of induced discharge in spacecraft operating environment and the design of protection methods.
