| 摘 要： | 针对兰州重离子加速器冷却储存环（HIRFL-CSR）的分离扇回旋加速器（SSC）的等时场优化问题，依托HIRFL-CSR的主数据库系统Oracle，设计了系统控制界面，该界面不仅能够读取和给定电源电流值，而且能够实时更新束流相位信息。根据束流相位的实时数据，利用Kb-Kr方法以及Lagrange插值算法建立的等时场，实现了对SSC束流等时场的在线优化。优化后的等时场可以有效控制束流相位的漂移，提高束流品质。

| Abstract: | This paper introduces the design and optimization of the isochronous field of separated-sector cyclotron (SSC) in the cooling storage ring of the Heavy Ion Accelerator in Lanzhou (HIRFL-CSR). Based on the HIRFL-CSR main Oracle database system, the main interface of the control system is designed. Through this interface, the values of power supply current can be given and read, and the beam phase information can be updated in real time. The isochronous magnetic field model is established by Kr-Kb and Lagrange methods, and the field is optimized on the basis of the actual phase measurement. The optimization of the isochronous field improves the beam quality by effective control of the drift of beam phase. |
