Injection: Electron beams [PDF]

open access: yes, 2018
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 ...
