合肥同步辐射光源上的束腔不稳定性研究

STUDY OF BEAM CAVITY INSTABILITY ON HEFEI LIGHT SOURCE

束腔相互作用激发的束流不稳定性是目前高能电子加速器上最重要的不稳定性之一。本文从粒子纵向运动基本方程出发，详尽分析了单束团和多束团情况下束腔纵向偶极不稳定性，并给出了我国合肥同步辐射光源上的计算和实验结果。

Beam longitudinal instabilities excited by the beam cavity interaction are one of the most important instabilities in the high energy electron accelerators. Based on the longitudinal motion equation of the particle, the longitudinal instability of m =1 mode excited by the beam cavity interaction in the cases of single bunch and multi bunch operations was discussed in detail. The results for the Hefei Light Source were given
