电子直线加速器中的束团整形

Bunch Shaping in Electron Linear Accelerators

G. Ha, K. -J. Kim, P. Piot, J. G. Power, Y. Sun

摘要:

现代电子直线加速器通常被设计成产生以其宏观系综平均矩为特征的平滑聚束分布。然而,越来越多的加速器应用要求对射束分布进行更精细的控制,例如,通过要求其沿着一个坐标的投影具有特定形状。最终,在单粒子水平上控制束流分布可以为加速器科学带来新的机遇。这篇综述讨论了最近的进展,控制电子束分布的“介观”尺度上的重点成形的光束或引入复杂的相关性所需的一些应用。本文重点介绍了基于有界外电磁场或通过与自生速度场和辐射场相互作用的电子束团成形方法的实验和理论发展。

英文摘要:

Modern electron linear accelerators are often designed to produce smooth bunch distributions characterized by their macroscopic ensemble-average moments. However, an increasing number of accelerator applications call for finer control over the beam distribution, e.g., by requiring specific shapes for its projection along one coordinate. Ultimately, the control of the beam distribution at the single-particle level could enable new opportunities in accelerator science. This review discusses the recent progress toward controlling electron beam distributions on the "mesoscopic" scale with an emphasis on shaping the beam or introducing complex correlations required for some applications. This review emphasizes experimental and theoretical developments of electron-bunch shaping methods based on bounded external electromagnetic fields or via interactions with the self-generated velocity and radiation fields.
