Description
The intensity and quality of the extracted beam are critically influenced by the central region structure. Variations in the central region design can lead to difference in beam transmission efficiency, largely attributable to divergent acceleration dynamics during the initial few turns. In cyclotrons employing internal ion sources, the very low beam energy at the source outlet makes the beam highly sensitive to changes in the central region design. Therefore, optimizing the central region is necessary to ensure high transmission efficiency and better beam quality. This study presents a conceptual design simulation for the central region of a compact superconducting cyclotron designed for radioisotope production. Beam trajectory and centering are optimized through adjusments of the ion source position, the dircetion of the opening slit, and puller electrode geometry.
