| Abstract: | Secondary electron emission(SEE) yield is one important factor for the flashover phenomena of solid materials under high electric field in vacuum.On the basis of the novel low melting temperature machinable glass ceramics for vacuum insulation system,which has excellent machinable performance and good electrical properties,different low SEE yield metal oxides including Cu2O and Cr2O3 are doped into the original glass ceramics while keeping its machinable performance,to investigate the effects of different p... |
