| 摘 要： | 合肥光源二期工程中注入系统改造后，凸轨系统的所有元件放置在同一个长直线节，这样增加了两块色品校正六极铁，动力学孔径有明显的增大，若色品校正六极铁从原来的两组改为三组，则动力学孔径会进一步增大．计算也表明，当高频电压从原来的０ ．１ Ｍ Ｖ 提高到０ ．２ Ｍ Ｖ，储存环束流的托歇克寿命也将增加一倍 |
| 关 键 词： | 高亮度 动力学孔径 托歇克寿命 |

| Abstract: | Some HLS (Hefei Light Source) storage ring parameters have been changed after the injection system of HLS is upgraded in NSRL phase II project. Calculation shows that the dynamic aperture is obviously enlarged after two chromaticity correction sextupoles are added to the storage ring. Further investigation shows that the dynamic aperture is enlarged even more while three families of sextupoles are adopted. Touschek lifetime of beam current will increase 70% while RF cavity voltage is increased from 0.1 MV to 0.2 MV. |
| Keywords: | high brilliance dynamic aperture Touschek Lifetime |
