“…In the previous studies, the value of the beam voltage or the cathode voltage was equal to 3150 V [6,10,15]. In other studies, this value was considered as 2750 v in [11], 4350 v in [5], 4880 v in [13] and 4920 v in [14]. Therefore, in this study, the effects of voltage changes on the improvement in TWT output power is studied using numerical solution of the governing equations.…”

In the present research, the effect of variations of the electron beam voltage on the output power is studied. In order to develop the study, this problem was investigated at different frequencies, which are the products of nonlinear behavior of the traveling wave tube (TWT) in response to the input frequency. Moreover, for a more realistic understanding, the tubes were considered with two linear and nonlinear responses to the input frequency. The TWT output power was calculated in linear and nonlinear modes, at different frequencies using the numerical solution of the mathematical equations of the Lagrangian model. Then, the output power in terms of distance and beam voltage in different frequencies was plotted and compared. The results revealed that the effects of variations of voltage on the output power were more proper in a singlemode TWT in comparison with a multimode one.
