Structure optimization of 142.8MHz sub-harmonic buncher
The structure optimization of 142.8MHz sub-harmonic buncher has been carried out with two-dimensional Finite Difference Method software Superfish and three-dimensional Finite Integration Method software MAFIA. The method of optimizing the cavity structure is presented in this paper, and the optimized structure of the cavity is also decided. The simulation results of Superfish and MAFIA are analyzed and compared, and they are consistent with the design data. In addition, the application of methods of Superfish and MAFIA in the cavity design are also investigated.
