The tank performance depends on a set of physical (beam characteristics) and geometrical parameters (radius and lengths of accelerating and coupling cavities, radius and thickness of the coupling holes among accelerating cells, the radius and the thickness of the coupling holes between off-axis coupling cells and accelerating ones). PSO (Particle Swarm Optimization) and ACO (Ant Colony Optimization) have been used as approaches for the electromagnetic optimization. The model used for the fitness calculation takes into account all the most important effects occurring in the tank coupled cavities loaded by the proton beam. The codes based on PSO and ACO have enabled the global and stochastic identification of about ten optimized parameters. The design goodness has been tested via Particle and Microwave CST Studio © simulation. The optimized tank accelerates the proton beam input energy from Ein=7 MeV to about Eout= 8.2 MeV. These values, well agree with other designs reported in literature.
