摘要
兰州重离子加速器冷却储存环(HIRFL CSR)由一个主环(CSRm)和实验环(CSRe)构成.两个储存环的束流注入与引出都需要借助于切割磁铁的导向来完成.介绍了CSR的切割磁铁的物理设计和二维场计算.
In order to satisfy the requirement of beam injection and extraction of CSR, four magnetic septums will be used in the accelerator. In the design, the shape of the lamination is optimized by 2D magnetic field calculation. Also, in order to decrease the leakage field and obtain a satisfied field distribution, a special auxiliary coil and a shield iron plate are considered and as well as the construction of the septum leg is treated in a special way. As a result, the leakage field is almost zero and the inhomogeneity is less than 0.1% even in the area very near to the septum leg.
