摘　　要：文章给出重离子（１００—２００ＭｅＶ）扫描磁铁物理设计的实用公式，指出这种磁铁系统工艺设计中应考虑的事项，并给出扫描磁铁系统的研制和实测结果。该磁铁最大可产生０５０Ｔ（Ｐ－Ｐ）的交流磁场，重复频率为５０Ｈｚ，通过３ｍ的漂移管道可将１６５ＭｅＶ７９Ｂｒ（１４＋）的离子扫宽０、４ｍ，满足了在ＨＩ－１３串列加速器上辐照ＰＥＴ一类膜材的要求，为生产核微孔膜高级滤材提供基本保证。The paper gives the practlcal formulae for designing the magnet system for heavy ions scanning. What should be considered in the technological design and the measurement results of the magnet system is also given. The magnet system, which produces maximum AC magnetic flux density of 0. 50T(p-p) with repeatation frequency of 50Hz, can scan the 165MeV 79Br14 + ions to a 0. 4m width after 3m drifting distance to meet the needs of irradiating PET film and to produce the high quality nuclear membrance filter.
