Methods for Full Global Optimization of Klystron Parameters

A single scheme of klystron parameter optimization is considered, which includes structure optimization and optimization of the maximum number of input parameters (all parameters of group B). This optimization had been called as the full global optimization (FGO). Discusses two methods FGO: stage-by-stage optimization for the standard configuration of the klystron and the embedding method for the klystron configuration with higher harmonics cavities. It is shown that both methods allow reaching the level of klystron efficiency up to 90%.
