eRHIC Electron-Ion Collider Advances and Opportunities*

The future electron-ion collider will open exciting new frontiers for research
in nuclear physics and QCD. The US nuclear physics community, with world-wide support, has compiled a comprehensive white paper that provides a detailed description of the potential of such a machine and the associated design requirements. Brookhaven National Laboratory is proposing eRHIC, an electron-ion collider based on the highly successful RHIC facility. An electron storage ring is planned to be installed in the existing RHIC tunnel to provide electron-ion collisions at
a center-of-mass energy of 29 to 140 GeV with luminosities up to 10^34 cm^-2 sec^-1. We will present latest design advances and opportunities of this proposed new facility.
