Abstract

The paper describes the design of an X-band coupled-cavity traveling-wave tube (CC-TWT) based on the ridge-loaded staggered single-slot rectangular coupled-cavity slow wave structure (SWS) using High Frequency Structure Simulator (HFSS) and particle-in-cell (PIC) code in Computer Simulation Technology (CST) Particle Studio. The working frequency range is from 8.6 to 9.5 GHz. The ridge can concentrate the longitudinal electric field in the structure so that the CC-TWT can produce 29.6 kW of saturated output power at 9 GHz with an electronic efficiency of 22.3 percent and a gain of 44.7 dB when the beam voltage is set to 26.9 kV and the beam current is set to 5 A.
