中文摘要	Quantitative analysis of the large-signal beam-wave interaction of coupled-cavity traveling-wave tube (TWT) is performed using three-dimensional PIC code. With an integrated model, an S-band CW coupled-cavity TWT is designed. The design parameters of this tube are: operating frequency from 2.0 GHz to 2.3 GHz, output power 4.3 kW, gain fluctuation +/-0.7 dB. In order to reduce the computing error of interaction impedance, a method using perturbation dielectric rod with large dielectric constant is proposed. Cold cavity characteristic of coupled-cavity TWT is also studied and the simulation results of dispersion and interaction impedance are given.
