Nonlinear theory and simulation of traveling wave tube for phase and gain matched operation

Designing an octave bandwidth helical traveling wave tube (TWT) for phase and gain matched operation in the EHF region presents many obstacles, for example the dimensional controls. Recent advance in computer modeling offer the possibility to evaluate the effect of slow-wave structure parameter and operating parameter variations, such as manufacturing tolerances, which will enable manufacturers to determine the cost effectiveness of controlling the dimensions of the component parts of the TWT. In this paper, computer code PGMTWT is programmed, which includes helical slow-wave circuit code and 2-Dimensional large-signal including harmonics interaction helical TWT interaction code. The effect on curve of gain and phase dispersion for frequency, when helical show-wave circuit parameter and operating parameter variate, is analyzed. Using this code it is possible, for the first time, to design a complete TWT via computer simulation.
