%X An important characteristic of the beam-wave interaction in traveling-wave tube is that the velocity modulation and bunching of electron beam, also its energy exchange with the RF field, happen continuously and simultaneously along the whole slow-wave structure. This is why traveling wave tube can offer large output power in a very broad band. On the basis of cold cavity characteristic research, quantitative analysis of the large signal beam-wave interaction of coupled-cavity traveling-wave tube is performed using three-dimensional PIC simulation code. In addition, an X-band CW coupled-cavity traveling-wave tube is designed with the design parameters as follows:operating frequency from 7.1GHz to 8.5GHz,bandwidth 18%,the highest output power of 3kW.
