| 摘 要： | 对传统双曲线极尖的四极透镜进行了磁性能分析。在此基础上，提出了极尖断面为折线的四极透镜结构。磁场的数值分析以及测量结果表明：该结构产生的场梯度均匀，且具有磁场集中、磁场梯度高、便于加工和安装的对称性控制等优点。该结构的四极透镜已用于ＣＹＣＩＡＥ－３０回旋加速器和ＨＩ－１３串列加速器束流输运线之中

| Abstract: | Most of quadrupole used for beam focusing possess hyperbola profile tip.To simplify machining processes and ensure the assembling accuracy,a broken line profile pole tip is adapted instead of hyperbola.The results of the magnetic field simulation codes and the tests show the good quality field generated by such configuration:not only more uniform field gradient,but also field more concentrated at useful area.These types of quadrupole are used at CYCIAE 30 cyclotron and HI 13 tandem transportation lines. |
