| Abstract: |
| Objective To study surface charging characteristics of Kapton material used typically on spacecraft under multifactor. Methods The experimental system was simulated through surface charged ground of space material. The surface charging process of spacecraft in charged environment was simulated with electron gun irradiation material. Surface charging characters of Kapton with different electron energy, flux density and thickness usually used as dielectric material in spacecraft were researched. Results The surface potential of Kapton increased with the increase of electron energy, flux density and thickness; the larger the electron energy and the flux density were; the shorter the charging balance time of the Kapton surface was. Conclusion The charging level of the spacecraft material’s surface is connected tightly with the electron energy and flux density of the charged space environment and the structure of the dielectric material. Research on charging characteristics of the Kapton material provides a data support for designing the spacecraft charging protection. |
