| 摘 要： | 基于ANSYS软件的建模与磁场有限元分析功能,实现了回旋加速器主磁铁的优化设计.给出了由滑相角度估算磁极张角修正量的方法,根据滑相角度计算磁场沿圆周的平均值与等时性场的偏差;为消除此偏差,将磁场沿圆周的分布做硬边界近似,估算出磁极几何尺寸(磁极张角)的修正量.利用ANSYS软件创建和修正磁铁模型,计算磁场;通过束流动力学分析给出设计磁场与等时性磁场的偏差,据此对磁铁进行不断修正,实现磁铁的优化设计计算.为完成上述功能,开发了应用软件CMEF,把ANSYS自动建模计算程序和束流动力学计算程序集成在一起,形成一个完整的回旋加速器主磁铁优化设计软件.

| Abstract: | The optimization design of the main magnet for cyclotrons was carried out by ANSYS modeling and magnetic field finite element analysis.The difference between the designed magnetic field and the desired synchronous field was analyzed according to the phase shift.The magnet size(here the angle of the magnetic pole was used) modification to eliminate the phase shift was estimated by using a hard-edge approximation to the magnetic field distribution along a circle.ANSYS was used to create and modify the magnet model,and to calculate the magnetic field.The magnetic field difference was found through the beam dynamics analysis,and used to perfect the magnet design.CMEF software was developed to integrate ANSYS modeling program and the beam dynamics program for performing the above design process. |
