Abstract :
In this paper, an optimization algorithm has been developed to provide robust designs for nonlinear beam-wave interaction of high-frequency traveling-wave tubes (TWTs). The algorithm utilizes the optimization method of hybrid genetic algorithm (Goldberg, 1990) in the TWT simulation code which is much like CHRISTINE-1D (Antonsen, 1998). By considering the effects of dimensional helix pitch variations during the optimization, the desired performance characteristics has been achieved.
