内置垫补线圈的C型二极磁铁

对HIRFL CSR的原形磁铁进行了试制和研究.尝试了一种新的改善磁场分布的方法:在不增大极头的条件下使用两根内置导线,实践证明是可行的.用OPERA 2D和TOSCA 3D软件分析了垫补电流对中、低场的影响,同时也介绍了这块C型二极磁铁的制作工艺及磁场测量结果. The C-type dipole prototypes in the injection beam line from a Separate Sector Cyclotron (SSC) to Cooling Storage Ring (CSR) are selected as R & D for CSR magnets fabrication, because they have large bending angle and small radius, and are very difficult to stack and fabricate. A method to obtain good field homogeneity has been attempted in the C-type dipole prototype. This method is not the enlarged dipole pole but two imbedded conductors and two small power supplies. This is easy operating....

A C-type Dipole with Imbedded Conductors

The C-type dipole prototypes in the injection beam line from a Separate Sector Cyclotron (SSC) to Cooling Storage Ring (CSR) are selected as R & D for CSR magnets fabrication, because they have large bending angle and small radius, and are very difficult to stack and fabricate.
