摘　　要：安装了ＥＣＲ离子源及其外注入系统后，增加了离子种类、提高了束流强度。扇聚焦等时性回旋加速器（ＳＦＣ）主要工作点分布于三次谐波加速区域，为了匹配外注入系统，仔细地研究了中心区，重新设计加工了Ｄ盒及假Ｄ。为了改进ＳＦＣ性能，提高运行效率，同时进行了其它改进工作．介绍了改进后的ＳＦＣ的调束工作。The ECR ion source,beam line from ECR to SFC and electrostatic inflector have been designed and installed to increase ion species and beam intensity.The working points are mainly located in the third harmonic accelerating region.The central region was studied carefully,and the Dee and dummy Dee were rebuilt to match the external injection system.Other improvements were adopted to improve the performance and operation efficiency of SFC.The commissioning of the upgraded SFC is also described.
