3D Mathematical Model for the Optimization of the Cyclotron Central Electrode Structure

Abstract

In this paper the new optimization algorithm for the central region electrode structuredefinition for the cyclotron is considered. The 3D electrical field maps for various accelerating gaps are used for the central region electrode structure optimization. The accelerating gappositions and other parameters are defined by assuming maximal ion energy gain per turn.The best configuration for 4 basic acceleration regimes was constructed for VINCY cyclotron.The beam dynamics analysis for the new configuration was performed. It was shown that the new configuration has much less beam losses and better ion centering.
