| Popis: | A superconducting magnet system for a 28 GHz ECR ion source DECRIS-SC2 was studied in order to select its parameters and optimize performance. Parametric magnetic models were performed for two design configurations, conventional ("sextupole-in-solenoid") and reversed ("solenoid-in-sextupole"). In the "sextupole-in-solenoid" design the racetrack coils of the sextupole magnet used for radial plasma confinement are located inside the solenoids producing the axial field. In the "solenoid-in-sextupole" design the coils arrangement is reversed. For both configurations, electromagnetic effect the booster and the steel poles on the magnet performance was investigated from the point of view critical parameters of the system ’ currents, fields, and forces. Results of the parametric computations were used to optimize the geometry and sizes of the magnet as well as the magnetic shield, the booster, and the poles. For better reliability and validation of the result, computations were performed with two magnetostatic codes, KOMPOT and KLONDIKE, utilizing the differential and integral formulations, respectively. A comparison of the obtained parameters was used to select the candidate magnet configuration for further design and manufacture.
