Abstract
An efficient non-stationary non-linear method, previously used to study the interaction in periodic coupled cavities traveling-wave tubes (TWT) in the one-dimensional case, is generalized to deal with periodic helix TWT and implemented in the 2.5-dimensional case via the development of a software. It is shown that the outputs of our program are in good agreement with the expected results and that the method employed allows to spare a lot of computational resources.
