Abstract :
Extended Interaction Klystrons have been demonstrated at frequencies up to 218 GHz CW and 229 GHz pulsed. Modern design, fabrication, and measurement technologies show promise of extending their operation into the THz regime. This paper describes the challenges and some novel approaches to the development of EIKs operating at 670, 850 and 1030 GHz, while simultaneously meeting demanding requirements for output power, gain, bandwidth, and efficiency.
