回旋加速器磁体的精细成形通常通过匹配所获得的和所需的预先计算的磁场的迭代过程来进行。然后通过所得离子旋转频率与其所需值的接近程度来评估所获得的磁场的质量。我们提出的方法是直接基于旋转频率的调整，因此，预先计算的磁场标准和经验的权重因子往往需要相应的形状估计被避免。该方法适用于在精细成形中使用的磁体元件的角宽度以及厚度。
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 pre-calculated magnetic field criterion and the empirical weight factors often needed for the corresponding shape estimate are avoided. The method is applicable to the angular width as well as the thickness of the magnet elements used in fine shaping.
