摘要：

Emission　properties　of　Scandia　Doped　Dispenser　(SDD)　cathodes　tested　in　Pierce　Gun　open　structures　have　been　reported　in　this　paper.　80-100　A/cm　2　Space　-　Charge　Limited　(　SCL)　current　densities　have　been　obtained　at　designed　anode　voltages　and　normal　operating　temperatures　for　cathodes　with　either　flat　surfaces　or　concave　surfaces.　The　influences　of　anode　effects　on　cathodes,　which　appear　in　close　-　spaced　diodes,　are　discussed　in　the　paper.　©　2010　IEEE.
