| 摘 要： | 合肥光源二期工程改造的电子储存环调试过程中，发现多束团存储和运行时存在耦合束团不稳定性，严重地限制了注入的最高流强，并且影响了光源运行的质量。通过过正地增大正色品以及在储存环上插入八极磁铁，基本上抑制了横向的耦合束团不稳定性，保证了稳定注入束流300 mA的技术指标。

| Abstract: | During the commission of electron storage ring of HLS(phase Ⅱ reconstruction), it was found that there was coupled-bunch instability both in injection and operation. The coupled-bunch instability seriously limited the injection beam intensity, and affected the stabilization of operation of Hefei light source. By using over compensated chromaticity and insertion octupole magnet in storage ring, the transverse coupled-bunch instability was almost suppressed, and the design goal of storing 300 mA was achieved. |
