We studied the measurement of photoelectron emission (PE) of metal and insulating materials used for thermal insulation on satellites or other such purposes. The PE measurement is very important for analyzing charge accumulation on satellite surfaces in a space environment because photoelectron emission is related to the amount of surface charge. Based on these photoemission characteristics, we deduce...
We studied measurement of secondary electron emission (SEE) of metal and insulating materials used for satellite thermal insulation or other such purposes. The SEE yield measurement is very important for analyzing charge accumulation on satellite surfaces for a space environment because electron emission related to irradiated electrons influences the amount of surface charge. Therefore, we tried to...
Recently, some accidents in spacecraft due to charging up by irradiation of charged particles have been reported. Some of them are caused by a surface discharge, which normally takes place in a plasma environment in space. Some others seem to be caused by a discharge due to an accumulation of charge in the bulk of materials in a relatively high-altitude environment. To investigate the charge accumulation...
