Abstract :
The lepton ring of eRHIC is being designed to provide intense, highly polarized electron and positron beams at 5-10 GeV energy range for the high luminosity lepton-hadron collisions. In this paper the estimates of major beam instabilities in the lepton storage ring are presented. Besides conventional impedance-driven instablities the fast beam-ion instability and electron cloud effects are major concerns. The studies suggest that those instbilities would not limit the performance of the lepton ring of eRHIC.
