标题： The RTA Betatron-Node Experiment: Limiting Cumulative BBU Growth In A Linear Periodic System

摘要： 基于扩展相对论速调管的双束加速器的成功运行取决于将累积的偶极子BBU增长从指数增长降低到更易管理的线性增长速率。 我们描述了实现这一目标的理论方案，以及一项新的实验来验证这一概念。 该实验使用1兆电子伏特、600安培、200纳秒的电子束和一个由周期性排列的射频偶极子模式圆柱腔和螺线管磁铁组成的短束流传输线。 介绍了束流传输线的描述，随后进行了束流传输和偶极子模式增长的理论研究。 显示英文摘要

摘要： The successful operation of a Two-Beam accelerator based on extended relativistic klystrons hinges upon decreasing the cumulative dipole BBU growth from an exponential to a more manageable linear growth rate. We describe the theoretical scheme to achieve this, and a new experiment to test this concept. The experiment utilizes a 1-MeV, 600-Amp, 200-ns electron beam and a short beamline of periodically-spaced rf dipole-mode pillbox cavities and solenoid magnets for transport. Descriptions of the beamline are presented, followed by theoretical studies of the beam transport and dipole-mode growth.
