Beam injection into electron (or positron) rings is the subject of this lecture. Through synchrotron radiation damping, top-up injection is realised: the beam current is kept essentially constant by injecting electrons/positrons atop of the stored beam to compensate for particle loss. Top-up operation mode maximises the output of the accelerator, namely the integrated luminosity in lepton colliders and the photon flux in light sources. The history of top-up injection is briefly reviewed, and Liouville's theorem and synchrotron radiation damping are expounded from the view point of top-up injection. Finally various top-up injection schemes are explained together with advantages and disadvantages.Downloads
