AbstractWe studied how to measure the secondary electron emission (SEE) of metal and insulating materials used for satellite thermal insulation or other such purposes. SEE yield measurement is very important for analyzing charge accumulation on the satellite surfaces due to the space environment because electron emission for irradiated electrons influences the amount of surface charge. Therefore, we are developing the measurement system without the deceleration voltage and enable to obtain the characteristics of the SEE yield from insulation materials irradiated by an electron beam with energy of 200 eV to 10 keV. This report introduces the developed measurement system and the SEE yield measurement results of metal sample and polymer. From those results, we discuss the characteristics of SEE that depend on each material. Furthermore, we also propose a future plan of SEE measurement for satellite materials.
