Abstract：

The　evaporated　substance　of　Scandia　doped　impregnated　dispenser　cathode　is　mainly　composed　of　Ba　and　BaO　and　Ba　evaporated　more　easily　than　BaO　from　the　surface　of　the　scandate　cathode,　which　is　consistent　with　the　result　of　impregnated　Ba-W　cathode.　However,　the　evaporation　rate　of　total　substance　and　the　evaporated　amount　of　Ba　and　BaO　from　the　scandate　dispenser　cathode　are　lower　than　those　from　impregnated　Ba-W　and　M　-type　cathodes.　©　2010　IEEE.
