束团伸长效应的理论研究
-
摘要: 论述了束团伸长效应现有理论的不足和困难。在强流条件下，用统计力学理论解出粒子纵向分布函数，从而将目前关于束团伸长现象的平衡理论和微波不稳定性理论用统一的形式加以描述。并且在理论上证明了束团伸长效应在本质上是多束团效应，指出了窄带阻抗对束团伸长效应的重要贡献。Abstract: The distribution function of the particles is gained with the statistical mechanics method for intense beam. The theory unites the existing potential well distortion theory and the microwave instability to explain the bunch lengthening. It is more important that the theory proves the bunch lengthening is a multi-bunch effect in nature. So the importance of the narrow-band impedance to the bunch lengthening is pointed out.
