Brief history of the Electron Ion Collider....

EIC = eRHIC + EPIC

The EPIC Project:

Polarized electron and polarized proton/light-ion collider with 3-5 GeV polarized electrons and 30-50 GeV polarized protons or light ions. The physics motivation and potential for such a collider were studied at the following EPIC workshops:
• The EPIC Workshop at MIT, September 14-16, 2000
• The EPIC Workshop at IUCF, April 8-11, 1999

The eRHIC at BNL:

Possibility of a future Polarized e-p & e-A Collider at BNL using the existing RHIC ring and to that adding an electron beam facility of about 10 GeV beam energy and of high polarization. Polarized ep collisions with 10 GeV electrons and 250 GeV (RHIC) polarized protons are envisioned. The 10 GeV electrons could also collide with the 100 GeV/A RHIC heavy ion beam to explore the nuclear structure at high parton density. This option was studied in the following dedicated workshops:
• A Summer Theory Workshop at BNL, June 24-July 14, 2000
• The eRHIC Workshop at Yale University, April 6-8, 2000
• The eRHIC Workshop at BNL, December 3 & 4, 1999
