摘要：

Vacuum　electron　apparatus　has　a　wide　application　in　civil　and　military　field,　such　as　communication,　broadcastings　and　aviation　industry　[1-3].　An　increase　of　current　density　cathode　at　a　given　working　temperature　is　a　main　trend　in　the　development　of　thermionic　cathode　for　different　in　vacuum　devices.　Among　all　the　electron　emitters,　Scandate　cathodes　have　aroused　great　attention　among　all　the　thermionic　cathodes　due　to　their　high　current　density[4-6].　©　2010　IEEE.
