摘要
在理论分析的基础上,开发了直线感应加速器束流崩溃不稳定性数值模拟程序。描述了利用该程序开展的研究工作,这些研究揭示了束流崩溃不稳定性的一般规律,分析了相关参数对束流崩溃不稳定性的影响,最后提出了直线感应加速器束流崩溃不稳定性抑制方法。
A code is written to simulate BBU in induction linac according to theoretic analysis. The general form of evolution of BBU in induction linac is investigated at first, then the effect of related parameters on BBU is analyzed, for example, the alignment error, oscillation frequency of beam centroid, beam pulse shape and acceleration gradient. At last measures are put forward to damp beam breakup unstability.
