- Abstract
Charges accumulate on spacecraft surface trough various processes such as including conduction, irradiation, ionization and polarization. These charges can affect the space system operations via an electric current flowing in the structure or a locally generated electric field. This work is focussed on the analysis of electron behavior in polymeric films such as PolyMethylMetaAcrylate (PMMA) and Teflon, subjected to an electronic irradiation. The charge distribution is detected in-situ by Pulsed Electro-Acoustic (PEA) method. Surface potential and surface current measurements are also performed to get further information on the charge displacement with time., JAXA Special Publication, 宇宙航空研究開発機構特別資料
