The fine shaping of a cyclotron magnet is usually conducted through an iterative procedure by matching the obtained and the required pre-calculated magnetic field. The quality of the obtained magnetic field is then evaluated by the closeness of the resulting ion gyration frequency to its required value. The method we propose is based directly on the gyration frequency adjustment; therefore, the pr... View full abstract»
