| Abstract |
In an electron accelerator, ions generated from the residual gas by the circulating electrons act back to the trailing electrons. Under unfavorable conditions this feed-back can cause unstable motion of the electron bunches, the process known as the fast beam ion instability. Current eRHIC design has two FFAG rings transporting 21 electron beams at 11 different energies. In this study, we use numerical simulation to investigate the fast ion instability in this complicated system, compare the simulation results with theory and discuss possible measures to mitigate the instability.
