摘要
介绍了非均匀绕线技术和匀场环技术在螺线管线圈设计中的应用。分析表明这两种技术的采用可以减小线圈间隙的磁场波动、屏蔽线圈磁场的横向分量,从而设计出宽平顶低横向场分量的螺线管线圈。针对中国工程物理研究院12 MeV直线感应加速器螺旋管线圈的设计结果表明,非均匀绕线技术可以使线圈间隙处的轴向磁场波动减小约70%,匀场环的采用则能使线圈磁场的横向分量减小96.5%。
A wide flat-topped low transverse error field solenoid magnet design for linear induction accelerator is presented. The design features non-uniform winding to reduce field fluctuation due to the magnets' gap, and homogenizer rings within the solenoid to greatly reduce the effects of winding errors. Numerical modeling of several designs for 12 MeV linear induction accelera tor(LIA) in China Academy of Engineering Physics has demonstrated that by using these two techniques the magnetic field fluctuations in the accelerator gap can be reduced by 7.0% and the transverse error field can be reduced by 96.5%.
