Surface breakdown property of SiO2 added MgO under electron bombardment in vacuum: a promising materials for spacecraft and space station

A surface breakdown (flashover) might occur on the surface of an insulator when it was bombarded by electron beam until exceeding a critical value. The strength of SiO2 added MgO to withstand flashover treeing appearance was evaluated by bombarding the samples by 25 keV electron beam generated by a...
