Abstract
One-dimensional large signal (nonlinear) models for coupled-cavity and helix travelling wave tubes (TWTs) were developed. These models are at least 5 to 6 times faster than the other known large-signal models with no loss in accuracy and present detailed description of the rf circuit field and modulated beam characteristics along a tube and at the output, in both tabulated and graphical forms. This paper describes the details of the generated output from the large signal models for helix and coupled-cavity TWTs and how such outputs can be interpreted for analysing the performances of different types of TWTs.
