摘要：

The　experimental　study　on　electron　guns　with　high　current　density　beam　for　THz　devices　is　carried　out.　A　thermionic　electron　gun　is　designed　and　the　fabrication　is　underway.　The　current　density　requirement　at　the　circuit　is　＞50　A/cm2　for　0.1　THz　LIGA　fabricated　devices　[1].　A　rectangular　sheet　electron　beam　for　0.5THz　needs　to　meet　the　beam　current　density　requirement　of　＞150　A/cm2　[2].
