TUIDCC002	eRHIC Multi-Pass ERL
	V. Ptitsyn BNL, Upton, Long Island, New York, USA
	The talk concentrates on accelerator physics and accelerator technology issues related with the multi-pass ERL of ERL-Ring design option of future high luminosity electron-hadron collider eRHIC. 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.
