标题： Theory and Suppression of Multibunch Beam Breakup in Linear Colliders

摘要： 我们最近发展了一种累积多束团横向分裂的解析理论，该理论包括沿束团序列的横向聚焦的线性变化。 聚焦的变化抑制了束团分裂的指数增长，并建立了横向束团位移与束团序号的代数衰减。 在本文中，我们说明了聚焦变化如何抑制多束团束团分裂，以及该机制如何随着加速器和束流参数进行变化。 显示英文摘要

摘要： We recently developed an analytic theory of cumulative multibunch beam breakup that includes a linear variation of transverse focusing across the bunch train. The focusing variation saturates the exponential growth of the beam breakup and establishes an algebraic decay of the transverse bunch displacement versus bunch number. In this paper we illustrate how the focusing variation works to suppress multibunch beam breakup, as well as how the mechanism scales with accelerator and beam parameters.
