Abstract：

High　current　density　scandate　cathodes　have　aroused　great　interest　in　recent　years.　In　this　paper　the　emission　performances　of　scandate　cathodes　and　the　possible　chemical　and　physical　processes　occurred　during　cathode　manufacturing　and　operation　are　summarized.　Emission　mechanisms　are　further　discussed.　The　major　problems　of　this　kind　of　cathode　and　its　application　prospects　are　reviewed.　©　2012　IEEE.
