The system would operate in a full energy range of proton beams (100 - 270 GeV) and would provide 50-100 A electron beams, circulating in a cooler ring for 5 ms. Every 5 ms a new electron pulse would be injected into the cooler ring to provide continuous cooling at collisions. Operations with a 10-ms cycle is possible but it will reduce the cooling rates by ~30$\\%$. The system is capable of delivering the required performance in the entire EIC energy range with emitta","authors_text":"A. Burov, A. Saini, I. Gonin, I. Terechkine, N. Solyak, S. Nagaitsev, V.
