A 1-D multifrequency non-linear model of the beam-wave interaction in a helix TWT is described. The field, phase and motion equations which contains the space charge field and the equations of the cut area are represented. Taking into account the voltage depression effect, this model has been implemented in a code which contains the functions of scanning beam voltage and input power, which is convenient for the simulation of the interaction of beam and wave. A TWT interaction is simulated by the code and the results from the code. The effects of the harmonic waves and the intermodulations are analyzed. The simulation is precise and rapid and it is of importance for the first and fast designs of a helix TWT.
