我们绕开了这一卷的主题，在存储环而不是单程系统的背景下讨论相干同步辐射(CSR)。在几个光源设施进行的一系列测量重新唤起了人们对这一主题的兴趣。有强有力的证据表明，观测到的相干信号伴随着光束不稳定，可能是由CSR本身驱动的。在这篇文章中，我们回顾了一个纵梁动力学的“自洽”模型，其中CSR是集合力的唯一作用力。该模型产生的数值解似乎再现了观测的主要特征。
We take a detour from the main theme of this volume and present a discussion of coherent synchrotron radiation (CSR) in the context of storage rings rather than single-pass systems. Interest in this topic has been revived by a series of measurements carried out at several light source facilities. There is strong evidence that the observed coherent signal is accompanied by a beam instability, possibly driven by CSR itself. In this paper we review a “self-consistent” model of longitudinal beam dynamics in which CSR is the only agent of collective forces. The model yields numerical solutions that appear to reproduce the main features of the observations.
