AC-type Dipole with Imbedded Conductor

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.<span style="color: rgb(51, 51, 51); font-family: arial, helvetica, sans-serif; font-size: 13px; line-height: 22px; background-color: rgb(248, 248, 248);">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 &amp;. 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 and lower cost. It is proved that this is a good way to improve the quality of dipoles. The fabrication technic and measured results are also involved in this article</span
