Abstract
In this paper, the effects of these structure parameters variations on performances of TWT are investigated. Therein, the working voltage can be determined from the dispersion curve of the slow-wave structure, as shown in Fig. 2, and the amplitude-frequency characteristics can be predicted from the frequency spectrums of input and output power, as shown in Fig. 3 and Fig. 4, by particle-in-cell (PIC) simulations. These results will favor the design of the circularly polarized traveling-wave tube.
