最近对各种粒子的高强度束流的需求重新引起了人们对线性射频和感应加速器以及束流传输通道中束流和束流质量限制研究的兴趣。回顾了以前的理论工作，并概述了光束匹配和稳定性方面的新工作。有一个真实的需要扩展的理论来处理束流发射度的时间演化，目前的一些工作朝着这个目标进行了描述。强调了物理约束在信道强度限制中的作用。关于优化通道性能的工作，特别是在低颗粒速度下的工作，已经取得了重大的技术进步。将这些通道组合成阵列的机会进行了讨论。
Recent demand for high-intensity beams of various particles has renewed interest in the investigation of beam current and beam quality limits in linear RF and induction accelerators and beam-transport channels. Previous theoretical work is reviewed, and new work on beam matching and stability is outlined. There is a real need for extending the theory to handle the time evolution of beam emittance; some present work toward this goal is described. The role of physical constraints in channel intensity limitation is emphasized. Work on optimizing channel performance, particularly at low particle velocities, has resulted in major technological advances. The opportunities for combining such channels into arrays are discussed.
