Abstract :
Aiming at the beam-wave interaction in the helix TWTA, some of the main calculation results which were based on the loss transmission line model and kinetics equation with the particle-in-cell technic of the time-domain were shown in this paper. Comparison of the test results, it is apparent to see the two results were consistent. Secondly aiming at the nonlinear phase distortion, a result of phase length is shown in the later. The calculation result is 45 degrees which is close to the test of the institute (IECAS).
