为了防止耦合聚束不稳定性和/或增加聚束寿命，考虑了具有无源高次谐波腔的双RF腔系统。表达式的发病平衡相不稳定性，频率和阻尼率的罗宾逊不稳定性，同步加速器频率，同步加速器频率扩展，和束长度。本文提出了一种计算无源高次谐波谐振腔性能的算法，并将其应用于正在安装的SRRC电子储存环。
A double RF-cavity system with a passive higher-harmonic cavity is considered for the purpose of preventing coupled-bunch instabilities and/or increasing the bunch lifetime. Expressions are presented for the onset of the equilibrium phase instability, the frequency and damping rate of the Robinson instability, the synchrotron frequency, synchrotron frequency spread, and bunch length. An algorithm is presented for evaluating the performance of a passive higher-harmonic cavity, and applied to the SRRC electron storage ring, which is being installed.>
