Wake Fields and Impedance

L. Palumbo, V. G. Vaccaro, M. Zobov

摘要:

为了优化加速器在储存电流方面的性能,束流和周围真空室之间的电磁相互作用的知识是必要的。由于电子束所产生的场,并像反馈装置那样反作用于电子束本身,所以在机器中可能发生许多不稳定现象。基本上,这些场产生额外的电压和能量增益,影响纵向动力学,以及使束偏转的横向动量反冲。在本文中,我们描述了这种相互作用的主要特点与典型的机器部件。

英文摘要:

Knowledge of the electromagnetic interaction between a beam and the surrounding vacuum chamber is necessary in order to optimize the accelerator performance in terms of stored current. Many instability phenomena may occur in the machine because of the fields produced by the beam and acting back on itself as in a feedback device. Basically, these fields produce an extra voltage and energy gain, affecting the longitudinal dynamics, and a transverse momentum kick which deflects the beam. In this paper we describe the main features of this interaction with typical machine components.
