Miniature Electron Sources for Tomorrow's Vacuum THz Devices (MiPRI)

Abstract

The most significant experimental accomplishment was the demonstration that plasma-assisted miniature cathodes can generate high perveance electron beams at low voltages (>1000A/sq cm; 0.5-3kV), and that those beams could propagate without external guiding magnetic fields over distances compatible with the length of the RF structure of THz sources. Our theoretical studies showed that this will enable the design of future THz sources operating with relatively high efficiency at high power levels.
