ABSTRACT
As discussed in depth in this book, one of the central problems of classical electrodynamics is the radiation of electromagnetic waves by an accelerated charge distribution. In this chapter, we first consider the theoretical description of the radiation for a high-charge electron bunch, such as those produced by a radio-frequency (rf) photoinjector, propagating on fixed trajectories through a helically polarized wiggler. The second topic described here is the self-consistent perturbation theory for a relativistic charged fluid, which is developed within the context of the so-called Eulerian formalism.
