A linear two beam theory of ion trapping is applied to calculate the threshold current and growth time of the instability.
首先用离子俘获的线性两束流理论定量计算了离子引起的二极耦合束团不稳定性发生的阈值束流流强和不稳定性的增长时间 ,然后用基于束流 -离子强弱作用模型的模拟程序跟踪了在实验情况下束流与离子的相互作用过程 ,跟踪结果成功地再现了离子引起的二极耦合束团不稳定性边带 ,并给出了比较合理的不稳定性增长时
The conditions for ion trapping are studied in the case of uniformly distributed electron bunches and bunch trains in storage rings based on the linear theory.
从线性理论出发，研究了电子束团在储存环里均匀分布和束团串两种情况下离子俘获的条件；在离子系统里引入Twiss参量，推导出电子束团串俘获离子的阈值流强的公式；并以此讨论北京正负电子对撞机（BEPC）在同步辐射专用运行时观察到的电子束流现象，提出采用束团串运行来克服BEPC中的束流寿命下降。
