高能同步加速器中相干非线性现象的观测与理论模型

Coherent Nonlinear Phenomena in High Energy Synchrotrons: Observations and Theoretical Models

P. L. Colestock, L. K. Spentzouris, S. I. Tzenov

摘要:

非线性波在同步加速器中已被观察多年,但在文献中很少受到关注。虽然这些现象是病态的,但至少有两个原因值得研究。首先,孤立波的形成可能导致液滴的形成,从而导致显著的束晕的发展。其次,各种非线性过程可能涉及不稳定振荡的正常饱和,导致低水平的可能性,但潜在的宽带波动谱可能会发展。这两个特征间接地携带机器阻抗的特征。在这项工作中,我们回顾了一些非线性纵波在费米实验室加速器的观察,并首次尝试发展适当的理论模型来解释这些观察。

英文摘要:

Nonlinear waves have been observed in synchrotrons for years but have received little attention in the literature. While pathological, these phenomena are worth studying on at least two accounts. First, the formation of solitary waves may lead to droplet formation that causes significant beam halo to develop. Secondly, a variety of nonlinear processes are likely involved in the normal saturation of unstable oscillations, leading to the possibility that low-level, but potentially broadband fluctuation spectra may develop. Both features carry indirectly the signature of the machine impedance. In this work we review a number of observations of nonlinear longitudinal waves made in Fermilab accelerators, and make a first attempt to develop appropriate theoretical models to explain these observations.
