| 摘 要： | 通过解析的方法分析了储存环在部分填充情况下的纵向耦合不稳定性,给出了不稳定性增长率和同步振荡频移的表达式.得到了一个有趣的结果:虚部阻抗对不稳定性的增长率也有贡献.这一点和均匀填充情况是不一样的.

| Abstract: | Longitudinal coupled bunch instability in fractionally filled storage rings is studied in this paper with analytic method to derive the expression for the growth rate of the instability as well as the synchrotron oscillation frequency shift. An interesting phenomenon has been found that imaginary part of impedance makes contribution to the growth rate of coupled bunch instability. This phenomenon is contrary to that in symmetrical bunch filling cases. |
