Abstract :
High current density cathodes are being developed for high frequency RF sources into the Terahertz regime. These cathodes allow significant reduction in cathode size, significantly improving performance and facilitating assembly of the RF device. High current density operation reduces, or eliminates, beam compression between the cathode and RF circuit. This is facilitating the development of a new generation of RF sources.
