Possible solutions for recirculating passes are described which include individual loops as well as FFAG-type re-circulations. Major beam dynamics effects dominating the ERL performance are described, which include electron beam disruption, multi-pass beam-break-up, preservation of transverse emittance and energy spread during acceleration and deceleration process. The recent design modifications of ERL-Ring eRHIC aim to balance technological risks and the project cost. PB - JACoW Publishing CP - Geneva, Switzerland ER -
