Gauss-Schell light sources are considered as models for synchrotron radiation. These sources can be viewed as random superpositions of coherent Gaussian beams. The relationships of the various widths that can be defined for the description of intensity and coherence, as related to the widths of the electron beam and the single-electron radiation (diffraction) pattern, are summarized. The description is also applied to the temporal coherence, which is of interest in the case of free-electron lasers.
高斯-谢尔光源被视为同步辐射的模型。这些光源可看作是相干高斯光束的随机叠加。总结了为描述强度和相干性而定义的各种宽度与电子束宽度及单电子辐射（衍射）图样宽度之间的关系。该描述也适用于时间相干性，这在自由电子激光器的情况下是令人感兴趣的。
