摘要：
We explore the effect of the e-beam energy distribution on the wiggler-undulator brightness. We show that a powerful tool of analysis is the expansion of a given distribution in series of Gaussians. The convenience of the method both for analytical and numerical purposes is stressed. We discuss two specific examples one of which being the brightness of the recently proposed two frequency undulator. The relevance of the analysis is also discussed within the framework of free electron laser physics.
