摘要：

The　development　of　high　current　density　sheet　beam　electron　gun　for　Terahertz　devices　is　carried-out.　It　operates　at　beam　voltage　of　12　kV　and　perveance　0.0136　μP　to　meet　ours　requirement　of　high　beam　current　density　100　A/cm2　and　low　emittance　0.068　π-mm-mrad　at　the　beam-waist　position.　Currently,　mentioned　gun　is　being　fabricated.　Work　has　been　initiated　to　test　the　performance　of　Scandate　cathode　using　anode-aperture　mapping.　Current　density　of　50　A/cm2　has　been　ensured　across　the　beam　cross-section　of　100　×　600　μm2.　©　2008　IEEE.
