High-frequency structure design of the 310GHz folded-waveguide extended interaction klystron and cold test of input cavity
2016
The preliminary design and particle simulation of high-frequency structure for 310GHz extended interaction klystron (EIK) with folded waveguide (FWG) as the resonant cavity was presented in this paper The validity of FWG slow-wave structure (SWS) as EIK resonant cavity was demonstrated. The simulation indicated that FWG cavities have high characteristic impedance and can generate high gain amplification. FWG-EIK could provide a new technical solution for THz-EIK study. The designed FWG-EIK can be fabricated by matured processing. The prototype of input and output cavities have been cold tested and the resonant frequency and reflection coefficient accord with the design.
