The large-signal code TESLA (Telegraphist's Equations Solution for Linear-beam Amplifiers) was originally developed for the analysis and design of klystrons. It has now been applied to the simulations of an extended interaction klystron (EIK) for the first time. Results for the power transfer curve and bandwidth curves computed for a G-band EIK compare well to their measured values. TESLA obtains...
Summary form only given.The development of terahertz power amplifiers presents significant new challenges as it brings into focus design, fabrication, and measurement issues that are not important factors at lower frequencies. We will describe our design approach to meet these challenges with particular emphasis on a 0.67 THz Extended-Interaction Klystron (EIK).One of the key design challenges is...
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...
