抄録(英)
Spacecraft are subject to build up charges inside dielectric films covering spacecraft for heat protection and electrical insulation. This will cause electrostatic discharge and may result in failures and anomalies. To avoid this problem, investigation of surface potential of dielectric films under electron irradiation is necessary. In the present study, time histories of surface potential on polyimide films under electron irradiation are investigated by numerical simulation. The charge density inside films is obtained by a Monte-Carlo particle tracking method. Results are verified with experimental data and discussion of the collision models is made. We can use this simulation for analyzing the cause of electric anomalies of spacecraft.
